NMI: Parity Check/ Memory Parity Error -- System crash

hey guys, i just seen this thread and was wondering if one of u could help me with my problem: http://forum.notebookreview.com/showthread.php?t=298466

getting hold of parts aint an issue except for the motherboard, so any suggestions welcome

 

Greetings

I've just spent the last four hours reading this thread. (Shinji, your input was particularly helpful.) After going through it it looks like there is neither a definite cause or fix to this. Most of the people who have seemed to fix the problem have done one or more of the following. Replace wireless/video drivers, replace the wireless card, or replace the video card.

I just started getting this error yesterday. I've had my laptop for three years with the same hardware and software drivers. (I haven't had any upgrades recently either.) So, I don't think it was caused by any change. I'm also getting the error as soon as I start. Literally, within seconds of hitting the on button. Which means the computer isn't even warm yet. So, I don't think this is directly heat related.

Since this is happening on startup, I can't even replace the drivers. My warranty ran out, so I may try replacing the video card myself. What sucks is I spent six hours working on a project, which is not trapped on that laptop.

My system:
Inspiron 6000
1,6GHZ PROCESSEUR PENTIUM M 2MB 533MHZ
DIMM,512MB,400,64X64,8K,200
INTEL2200,WRLES

 

Cyle - if this happens before Windows loads (or before you can enter the BIOS), then you have a hardware issue. I recommend you remove and reinstall your memory and any internal wifi cards you may have (if that's possible). Get a can of compressed air and give all vents a very good cleaning. Check all connections on the motherboard.

 

Dell replaced my motherboard and RAM, the error went away.

 

I have had that problem for way too long. Go to http://peter-shih.com/freeware.html and scroll down to "18KfanGUI". click the link and download the program. It lets you control the fans that cool your overheating chips. I haven't had a problem since.

This will fix the problem. It is an overheating problem. I havent had the problem since.

 

Thanks to all who have contributed to this thread. It's clear that this error is generic, with different root causes for different computers. It's still early for me, but I think GPU overheating is at fault on my machine. Here is a brief:

I have an E1705 with 7900gs video card. The BSOD happens only when I'm playing Civilization IV, typically within 10 minutes of game load. This game is the most taxing operation on my video card. I don't run any other graphic extensive application, though I play a lot of Football Manager 2008, which taxes the CPU, not the video card.

WHAT I'VE TRIED WITHOUT SUCCESS:
Updating to the latest video driver from nVidia
Disabling my wireless Network card
Updating the BIOS to A09
Changing/reseating RAM

WHY I THINK MY ERROR IS HEAT RELATED:
After reading much of this thread, I installed I8kfanGUI ( http://www.diefer.de/i8kfan/index.html) to monitor temperatures. I found out that my GPU temp was at 74-76C when idle. From what I've read, this is very hot indeed. I didn't even bother to check GPU temp while runing the game (I suspect it would rise in excess of 95C). I think temperature is to blame because when I used the fix below, the BSOD would disappear. Without the fix, the error would come up EVERY SINGLE TIME I played Civ IV, within 10 minutes.

MY TEMPORARY FIX:
I used I8kfanGUI to keep my fans on high. This lowered GPU temperature when idle from 75C to 66C roughly. In addition, I rested the laptop on icewater packs and this further lowered idle GPU temp to 50C. Maybe a laptop cooler would've worked, but I don't have one. I then loaded the game (Civilization IV). This time, with GPU temperature hovering at 70-75C during gameplay, the error didn't show up. Eventually, as the ice water pack became more water than ice, and then got warmer, the GPU temperature rose, and when it got hot enough the BSOD came back.

MY SUGGESTION:
Heat may not be the cause of your crash, but take the time to at least checkout that possibility by monitoring GPU temperature to see whether there is a correlation between high heat and system crash. If heat may be to blame, force your fans to spin at "high" setting -- I did this with I8kfanGUI ( http://www.diefer.de/i8kfan/index.html), use compressed air to clean out your vents, and consider getting a laptop cooler or making your own icepacks (more on that below). Maybe replacing the graphics card would provide a permanent fix, I don't know.

I haven't tried the following, but someone else suggested one way to check whether the problem may be caused by your video card. To read his instructions, go to http://forums.worldofwarcraft.com/thread.html?topicId=69639514&postId=57489076117&sid=1#74 , scroll down and find a posting by a user named "Parr"

HOW I MADE MY ICEPACKS:
For each pack, I used two 1-gallon ziplock bags. I bought the expensive kind with a dual layer film, and two sliding zippers to reduce leaking (about $4 for 13 bags I think). I filled one bag two-thirds of the way with water and I added about a third of a cup of table salt. I then securely sealed the bag, removing as much air as possible in the process. Next, I inserted the water filled bag inside the 2nd empty bag, to further prevent leaking. Finally, I layed the bag as flatly as possible in my freezer and waited 12hrs. Voila!

The salt will help prevent the water from freezing, so that the bag will remain flexible and will better hug the bottom of my laptop. I didn't completely fill the bag with water because if the water does freeze, it will expand and I don't want it to break the bag. An icepack can keep my GPU temp reasonably cool for 2 to 3hrs of gameplay when used in conjunction with the laptop's own fans.

FINAL THOUGHTS:
This is neither a permanent, nor an elegant fix, but it can be helpful for anyone who sees this error as a result of high heat. I make 3 or 4 ice packs at once because they take about 10-12hrs to get to freezing temperature. If you have a better way to address high heat, please post! Thanks for reading

I to have experience NMI parity error with Nvidia and Dell. - Will never buy another Dell computer. Dell is robbing consumers of money with inferior products and overcharging for useless support. More people need to be made aware. If there is a class action lawsuit, I'm onboard. - thanks for info.

 

SWITCHING VIDEO CARDS FIXED THIS

My Memory Parity Error seems resolved. I called Dell and explained what I told you guys two posts up. We ran an extended diagnostics (by holding down the Fn key as you power up the computer). After a quick 10 minutes diagnostics, I was given the option to run an extended diagnostics, and I chose to do so. It took a loooong time, but eventually, a video memory error popped up. I've reprinted the error message below:
===============================================
Error 5300:0119
Msg: Detected a failure while writing & reading video memory. Video Mode: 100h(640x400x256).

Address AO1O4h, expected to read FFFFFFFFh, but read FFFFF7FFh instead.
================================================

This error came up about 15 times, with different addresses and data. The Dell rep put me on hold to look into it. He came back 5 minutes later to simply tell me that I needed another video card. Didn't explain what was wrong with this one, or what may have caused this memory error.

My video card was replaced the next day by another of the same model (nVidia GeForce Go 7900gs), and since then, playing Civ IV - which caused the Memory Parity error 100% of the time on my machine - has given me no grief. Problem fixed, I think

Thank you again for all who contributed to this thread. You saved me lots of time because I refused to go through a motherboard swap (first thing Dell tech suggested), and I told them that I had already tried using different ram memory sticks (in fact, I hadn't).

Hi all!

For me the same problem that seems the plague everyone in this forum. Because there seems to be no single solution to this problem, I will just describe what I did to solve it. For me it became clear that either the ATIX1400 or the Intel ABG wireless card had something to do with it. Disabling the wireless card certainly helped but this is not a long term solution of course. As of now however I am running for about 2 months since the last parity error without any crashes at all. To accomplish this I tried various combinations of drivers for both the video card and the wireless card until I thought I had a stable and fast system. To be more specific.....

notebook: inspiron 6400.
video card: ATI X1400, driver version 8.411.0.0, 21-aug-07
wireless: intel 3945ABG, driver version 11.5.0.32, 26-sept-07
To install the ATI driver I used catalyst: 7-9-mobile_xp32_dd_ccc_enu_52445
The wireless driver is from package: R171132-network.exe

After installing the ATI driver, I completely disabled the ATI control center
(CLI, CCC, MOM) using msconfig, a tool for managing XP startup options.
As a replacement I am using ATI tray tools 1.36.1042 which works better anyway.

After doing all these steps I got a stable machine.

 

I had the parity error and was pulling out my hair trying to figure out the cause. I suspected my Atheros based SparkLAN WPEA-124N card. That ended up being the culprit, or more specifically the drivers were the cause. I found some modded Atheros drivers that fixed the problem - no more BSODs. So, in case anyone else has an Atheros wifi card, check out this link:

http://www.laptopvideo2go.com/forum/index.php?showtopic=15297

 

So I have this error. Started last January. First Dell replaced the motherboard, then the video card, then they told me it was a software issue. I reformatted... still got the message... then I was told it was my ram... replaced that.... now it's apparently my harddrive... seriously now. This is just frustrating. I dont think i will ever buy a dell ever again.

 

This error is among the most difficult to diagnose because just about anything can cause it. Virtually anything that uses any kind of memory in your system can cause this including your hard drive (it has a memory cache). Device drivers can cause this as they access device memory. If you are getting frustrated then going through unresolved issues with an open case may be your best choice. Try for a replacement unit but their job is to make sure your issue is fully resolved and you are satisfied. I did that after dealing with the issue for a couple of months and I have not seen the issue on the new laptop at all.

Dell Unresolved Issues:
https://support.dell.com/support/to...outstanding_issues?c=us&l=en&s=gen&redirect=1

Make sure to provide a brief but informative description of what has happened up until now.

 

They are saying that I am not eligible for a replacement. even with the 3 year complete care warranty. Unbelievable really. So I have to wait and see if the new hard drive will fix it. Too bad I will need to install everything AGAIN. Sounds like fun. Then we will see.
Anyone know what qualifies as a case for replacement?

 

Well in my case they had me send it in and it actually came back with the issue unresolved and unable to charge. It was able to charge before sending it in and they offered to replace it. Looks like their policy may of changed though since I had that happen.

 

I am having this NMI: Parity Check/ Memory Parity Error as well. It only happens when I am putting some high demands on my computer (playing left 4 dead). Annoying the hell out of me. I am trying the fan solution right now, but am thinking it won't fix the problem.

Oh, and my machine is a Dell Inspiron E1705
Processor
1.67 gigahertz Intel Core Duo
64 kilobyte primary memory cache
2048 kilobyte secondary memory cache
2 GB RAM
NVIDIA GeForce Go 7900 GS

 

I have had this problem for a while over the summer and, after trying possibly hundreds of things while hoping it is not a bad GPU, I finally concluded it was. The reason I reached this conclusion was that I would only get the NMI Parity error when playing graphics intense games, amongst some other things. I used Dell's diagnostics from the hard drive partition and it always showed an error with the GPU's VRAM. So, I went and bought another GPU from eBay and installed it. Now everything is running well and I am keeping the temperature below 65 degrees with I8kfangui even when gaming.

One good indicator of it being a GPU problem is to play a song in WMP. When the song starts playing you would normally see the background artistic visualizations but, in my case, it was always an almost instantaneous BSOD. I guess this put a lot of stress on the GPU. This is just a little FYI as it was a lot quicker of an indicator than having to game for half an hour before the BSOD happens. Trust me guys, if this NMI Parity error happens to you when gaming and in WMP, it is a GPU problem. Get a new one (part number DG008 for Nvidia Go 7900 GS) or a new laptop. I hoped for a long time it would be a cheaper component, such as RAM, but it is not.

HTH.

 

I have had my E1705 since December '08. I have been getting the NMI memory parity check error more often only when running graphics intnsive games. Last night after the BSOD, I got a black screen after rebooting. It finally came back presumably after the video card (Nvidia GeForce Go 7900 GS) cooled off. I will most likely call Dell and have them replace it since it is still under warranty.

 

I had the same thing on my 1705 when I got it a couple of years ago. The video card was bad. Dell sent me a new one and it has been running without an error since. Have you used the Dell diagnostics to test the card? It showed an error on mine so we knew that was the problem.

 

I saw this happen today on a Dell Latitude D620. BSOD immediately after the Dell splash, before getting to the Windows load screen.

I searched around the net for clues and saw that some of you had had success with simply updating the video drivers. I did this and it worked fine.

I gave the computer back to the owner, so we'll see if he gets the BSOD again.

 

I removed the diagnistics partition. Bloatware as far as I am concerned. Funny thing , I don't do anything differently and somtimes it doesnt happen for a few days. I havent called Dell support yet. It is so painful to call Dell. Always. Their incompetence level is off the charts.

 

Have anyone of you tried disabling your wireless card? I know I'm out of left field, but, had this same errror on a customer's system and I've been reading over all the pages in this forum trying to find a solution. Finally I just figured it must be the video card since changing memory and running memory diagnostics didn't seem to work.

I finally decided to put in a new HDD and install fresh copy of windows. everything worked fine, even after installing video drivers. Then, I installed the wireless drivers and BINGO! Memory Parity BSOD. I replaced original HDD and disable the wireless and no more error. I should've suspected when I noticed that it would blue screen if I booted into Safe Mode w/net but not normal Safe Mode. Anyway, might be worth a shot for those of you that still haven't been able to figure it out.

 

I just recently got this error message, too. It happened right after I opened up my Laptop to clean the fan, so clearly I did something, but I can't figure out what.

I have a Lenovo T60. The cooling fan had been making noise for a while. The other day I got an error message saying "Fan Error" and my computer wouldn't boot. I waited a few minutes and tried again and it booted up this time, but after a little while the fan started to make a lot of noise so I shut it down. I decided before I buy a new fan I would try cleaning this one and hopefully that would fix the problem.

I followed the directions I found online and in the Hardware Manual. I opened up my T60, took out the fan and sprayed it with compressed air to clean it. (I've read you shouldn't do this. Could it be bad for the fan?) I also sprayed and blew with my mouth in few other places where there was a lot of dust. I put everything back together and turned on my computer.

Immediately I saw trouble. The screen had a green line going down the right side and there were dotted lines behind the windows logo and any words. after continuing with the start up, the screen eventually goes black. I'm pretty sure the computer's fine it's just the image on the screen is black. That's when I got the "NMI: Parity Check / Memory Parity Error" message. I've turned my computer on a few times since and I haven't seen that message since, but I also haven't been able to get past the start up without the screen going blank.

I tried starting in Safe Mode and that worked fine. I then tried booting up in VGA Mode and that works too. When in VGA Mode the screen looks fine. No lines or dot's where they shouldn't be at all. As soon as I try to increase the resolution, though, the screen goes black again.

Does anyone have any ideas what I could have done to cause this problem? And any ideas how to fix it. I've tried taking out the RAM and putting it back in and there was no change in behavior.

Thanks,

Steve

EDIT: Actually since this isn't a dell problem, I've re-posted this in the Lenovo forums. If a moderator wants to delete this, I'll understand.

 

I too have been having the blue screen issue on my xps m1730. Only for the past 3 months though. Its during games that it really gets me. City of Heroes kos it in 30-40 minutes most times. I also notice that sometimes the fans seem to be running right.. and sometimes not. guess I will check on the price of a gpu.. but wow.. thats a long way from the result I want

 

Have the Problem with an --> IBM <--- Think centre, so don't kill Dell for that Error.

Are there anysolution so far?

*sorry for beeing to tired to read trough 68 sites ^-^

Peace

 

I second that motion.

 

Just thought I would add to the diversity of laptops affected by this.

My laptop below gets this problem as well. Unfortunately I haven't see any Gateways in this thread. Parity Error non-the-less however.

I will try disabling my wireless card and get back with the results sometime. My drivers are up to date, including current modded ATI drivers.

 

Okay, so I disabled the wireless drivers and tested my laptop using Warhammer Online, a game that most frequently gave me issues.

So far the results have been good. I played over two hours (where before I'd be lucky to get a half hour) and my temps lowered about 10-12 degrees (not sure why...but I'll take it).

EDIT: The temperature drop was a little exaggerated. To be honest, I'm not sure why it seems to sometimes run cooler (doesn't happen all the time). Perhaps it has to do with my room temp? Although I seem to still be having the odd graphic hick-up, I haven't seen a parity error.

Chack out that article, if you haven't already.

Basically, as is noted quite a few times, check the RAM.

Failing that, look at add-in cards. Remove any that are not necessary to boot into Windows. If that workd, replace them 1x1 and see if the error comes back.

Always try and update the BIOS, if it's available.

If those don't work, then chances are it's a problem on the motherboard, hard drive, or video controller.

And, just a note, no issue like this is limited to any brand of computer. If it has hardware, it can fail. HP, Gateway, Dell, Apple, you name it.

 

Just wanted to add my two cents to this thread since it seems like I might have finally gotten rid of this parity error thing for good (I hope!).

I have an Inspiron 9400 and for the past year and a half I had been getting the parity error at least two or three times a week and it was driving me NUTS! I was on the verge of ditching my laptop and getting another one because it was annoying the crap out of me having to reboot so often.

I tried everything I could think of and I was still getting the error. But recently I reinstalled my Win XP because it felt like it was running abit slow and I reinstalled all the programs I had on my previous installation EXCEPT the Notebook Hardware Control application which I didn't install just to see if it made any difference. And so far for the past three weeks I've been parity error/blue screen free!

So if you're still having this error and you have NHC installed, perhaps uninstall and see what happens. In my case, that seems to have been the problem. If I get the error again I'll update, but so far so good - Finally! I just wish I found this out much sooner so that I could have had a stable laptop for the past year+. Oh well.

Goodluck to everyone else in solving this problem.

 

For some reason I wasn't surprised to find this thread, my GFs xps m1330 just got hit by a series of the same bluescreen errors. (NMI: Parity check \ Memory parity error).

Something else that wasn't surprising is that Dell doesn't have a clue as to what is causing the fault.:confused2:

 

Hi all,

This BSOD error started happening to me after I had my screen replaced at home by a technician (started crashing in Google Earth). It was BSODing with the NMI error and the GPU temperature was only 55 C at the time.

So I re-assembled the laptop and it doesn't happen anymore. I'm guessing in my case it was down to a poor connection somewhere...

Cheap Dell junk... hehe

 

I started getting the same message a few weeks after I got my new Dell laptop (Vostro 1710).

Followed a number of suggestions on this board ... but in the end it turned out to be a problem with my internet connection -nothing to do with Dell.

I reported a problem to my ISP (cable company). First I got a new modem but that didn't fix the problem. Then they investigated some settings at their end - no idea what they did, but I haven't had a BSOD in over a week, and before I was getting it everytime I was connected to the internet.

I had assumed the parity check error meant there was a problem with my computer. In my case, it turned out not to be true.

 

I got the same error msg on my HP Compaq dc7900.
I`ve windows vista business installed on it.
Well, It worked fine untill I got a msg where I was suggested to install/update my multimedia audio controller device. The audio works anyway, but there is no driver installed for multimedia audio controller in "Device Manager".
Just for fun, I found the driver in google, and tried to install it. The driver is called something like C-Media driver. After a reboot, I started to get this error called "NMI: Parity Check/ Memory Parity Error -- System crash".

Solution!!!:
Get in to windows by safe mode and click start, programs, accessories, system tools and click system restore. Restore your computer to an earlier time before you installed the driver, and reboot your pc. This worked for me!!!

Thanx!

 

So just an update. Still been getting the blue screen of death. Harddrive did nothing. So they replaced the mother board again. Still nothing. I'm sending it in one last time and if it's not fixed, they are replacing my computer. 2 years and they haven't fixed my computer.

I can't pin point the cause as I could be doing something as simple as word processing, or browsing the internet, or I could be playing games like HL2 and such. It's just annoying.

Any Idea what Dell does for replacements? Do they maintain the similar specs? I'm worried they give me some POS replacement. I still need to have a dedicated vid card and such.

 

Just to add one more complaint to this pile.

I had a Insprion 9400 that exhibited this error from time to time. It seemed worst when I was experimenting with different video card drivers for the 7900 GS. Ram checked out OK as well.

 

Hi,

I have a Dell XPS M1710, 2.0 Ghz dual corse, 2 x 1 Gb Ram, 160gb HD, and I think GeForce Go 7950 GTX (or possibly GeForce Go 7900 GS). I am outside of warranty. It’s almost 2 years old.

It was fine, then suddenly I got the BSOD Memory Parity Error about 3 times (after maybe 10 mins of using the laptop). For a time after that, the screen was completely black after powering up. Using an external screen sometimes helped. Now the screen works most of the time, but it has 30 or so interference vertical lines across it whilst booting.

I have it set up as dual boot (XP and Vista).

I get BSOD when booting to Vista (including using “last know config”) unless I boot in safe mode, where it works fine. I’ve run memory and start up tests – no issues showing. I’ve installed the Nvida drivers. No change. However, the fact that the screen and graphics card outputs at all (albeit it in safe mode) makes me think maybe this is recoverable / fixable?

When booting to XP, the screen often doesn’t work at all. Last time, it was flickering on an off every second or so. That aside, it seemed to be functioning ok. Again, something odd with graphics, but possibly a driver issue? Or is this a hardware problem/

I need to fix this asap (this laptop is vital to both my jobs, and as a musician with gigs next week which I need the computer at, trying to restore all my software etc before then would night on impossible).

It seems this is a common problem. Is this fixable? There are numerous people who’ve got through several graphics cards, hard drives, complete reinstalls and/or motherboards to no avail. I don’t want to throw good money after bad, so what are my options?
1) Replace the graphics card, assuming I can find a Go 7900 GS or Go 7950 GTX (which so far, I haven’t).
a. Is this likely to fix the problem?
b. What other graphics cards would work with my XPS M1710.
2) Buy a s/h Dell M1710 and just transfer my harddrive to that (£500-600). Though I guess there’s a fair chance I’m likely to have the same problem again. This could work as a temporary solution whilst I get my M1710 fixed. I could then sell the s/h M1710,
3) Buy a new laptop (£800-1500, which I don’t have)… unlikely to be a Dell! (Any recommendations? At least 17” high res screen essential, along with firewire).
4) Something else…

Really grateful for any suggestions…

Cheers,

Dan

 

Sucks that you got that issue.

1a) This is your best bet here. The card is very likely going bad. You may be able to try the oven trick (search around a bit) but no guarantees. Never done it before. If it works then your card may be fixed. If it doesn't then you might of just ruined the card to the electronic graveyard. The other possibility is that the lcd cable is coming loose. You could try to reseat it but the Memory Parity Error more points at the video card itself.

1b) No other high-end cards work other than the ones you mentioned. I think the ATI X1400 would work but that will be an obvious downgrade.

3) I personally got a Gateway to replace my Dell but then I had no bad things to really complain about Dell for. I would always get an extended warranty for failures like what you may have going here as Dell has always been good about replacing parts. (Trust me they were very easy). Even then on your new laptop I would suggest considering it. If not at purchase time then do it later within your grace period. You will be glad later if you need to get it fixed past that magic 1 year mark.

 

I have experienced the same error during first months of use of this machine.

After some googling, I came to a decision not to use Dell stock drivers for GPU and motherboard. Haven't had this issue since. When my system requires a fresh reinstall, I just download the latest drivers from nVidia and Intel websites.

P.S.: After 2 and a half years of usage, I'm still very satisfied with this machine. It has issues, I admit, but, overall, 9400 is excellent.

 

Iv have just recently began dealing with this issue. After my 1330 made it's first trip to Dell minus my hard drive, i'm fairly certain that it is not hard ware. I believe I have narrowed it down to either the Hard Disk Failing or the Nvida Driver. My crash problems began after I last update my driver from the dell version to the the nvidia web site version. I'm not sure if my registry is screwed up somehow but I'm certain it's either the hard drive or stupid driver. Hope this helps to confirm for some what the problem may be.

 

Also I will be saving for my Mac PRO while I try to figure this out!!! They may be over priced but their stuff works well

 

I have through most of this thread (not all of it).

I have a E1505.
I was getting the same error message as everyone else. But I was getting mine at boot up. Everytime..... It would boot up to safe mode with no problems. Which lead me to suspect a software issue.
During my troubleshooting, I tried booting to Safe Mode w\networking to be able to download some Video drivers to try out. Low and behold I got the error again! Now the only other thing that is running at this point was my wireless. So I rebooted, this time into the bios and disabled the Wireless card. Now I can boot the computer normaly. I tried enabling and disabling the wireless card in th Bios multiple time, just to make sure it wasn't a fluke. The results were the same everytime!
When enabled, I got the error. When disabled, I was able to boot fine.

Luckily for me, I know someone with the same laptop (e1505). I swapped out the wireless card (DW1390) just to test it. Sure enough, the other laptop got the error, while mine did not.

I ended up buying one on ebay for $15. Have not had a problem since.

I hope this helps someone out.

A couple months ago I suddenly was getting an ATI Graphics Screen coming up at start up saying that I did not have permission to change Catalyst Control Setting and referred me to Administrator. This week I suddenly got a blue screen parity error. I contacted Dell Support and they ran diagnostics and everything was okay. They next attempted to install an earlier version of the driver for the ATI X1400 256MB Mobility Radeon HyperMemory. I got a clear screen one or two times out of twenty startups but the resolution was small, the colors deep, and no way to adjust. The remaining startup give me a low resolution screen that is grainy with lines as if started up in safe mode. Dell Support told me to reload OS Windows XP Media Edition but they had not provided me disc in purchase. I suggested Norton Ghost has restoral points in the past or restore to original factory condition. I want to avoid doing those because I have some software installed that I no longer have the programming disc like Photoshop CS3 that I would lose with reloading OS System. I cannot use laptop in its current condition and it is four days outside of my extended warranty. Suggestions?

 

I am now receiving NMI: Parity Check / Memory Parity Error ATI Graphics X1400 on Dell E1505 90% of regular start ups.

 

Ok I just started having this issue about 6 months ago. I have an E1705, GeForce Go 7900 GS, upgraded to 4GB aftermarket RAM, aftermarket Western Digital Black Edition 320GB 7200RPM hard drive, and upgraded to Windows 7 Enterprise RTM x86. System bluescreens randomly many times per week, graphics corruption present on BIOS, Dell diagnostics, Windows, and usually once it happens the system will not properly boot and graphics corruption remain for about 20 minutes. Is there a definite fix for this, or cause?

*** The system has halted ***

I've talked to Dell so many times and they haven't been willing to do anything until just today. I have a dedicated agent from the escilation/unresolved issue department working with me and I think he's willing to do pretty much anything to solve it. Is this issue specific to older Dell laptops like the E1705? I wonder if they just might give me something newer than in exchange. This problem is really irritating because it screws up Windows settings, Windows deletes all my cookies and personal information when the system shuts down properly, and I lose whatever I was doing when it happens. Windows just seems to glitch all over the place and I get unexplained errors as well.

 

Sounds like a bad video card to me. Can't really be certain but if they do replace your laptop there may be a good chance that it will be a newer model. Make sure you pay attention to the specs though. In my case I managed to get a proper replacement 3 months after the original purchase but my E1705 started showing the symptoms alot sooner than yours did.

 

VERY INTERESTING

 

Hi all. I have been getting this error message as well. I have a Dell E1705.

I've read through this thread some and have seen that the problem can be either RAM, the video card, wireless card, or maybe something else.

In the case of my computer, it has almost completely stopped booting. About one out of every ten times I will get the error message. When starting up, the computer can do a number of different things:
a) the screen may not come on, and the computer may not be warm to touch
b) the screen may come on, but it will have horizontal, moving white flickers with a black background
c) the screen may come on and start to boot but be a little garbled, and if it gets to the main desktop, usually has wavy horizontal lines, and will be very slow to operate if it does at all.

Does this help isolate which component of the computer is causing the error? Thanks for your help.
