weird 9800m gt issues

so i had to reformat just recently, and now im having weird problems with 9800m gt drivers from laptopvideo2go on my m860tu...everytime a driver finishes the install process i get a bsod....and when i benchmark im looking at scored 1000 pts lower on 3dmark with the same driver pre-reformat...any ideas?

 

make sure you fully remove the driver and its remnants... try doing uninstalling in Safe Mode

Then reinstall the drivers (latest and stable is recommend) with UAC disabled and driver signing disabled.

 

If you didn't have any troubles before reformatting, try what Gophn stated. I had some huge problems once trying to update drivers (could only use thoes delivered with the laptop, before getting a BIOS update), which resulted in BSOD, freezing and low scores, also at one point reinstalling orginal, normally working, drivers. A full removal of all GPU-driver related software had to be done from safe mode also had to do CCleaner reg cleanup to get it to work.

So boot in Safe Mode - Uninstall drivers - Reboot to Safe Mode - Run CCleaner reg clean up - Reboot to Safe Mode and install drivers (try latest from Sager or Clevo, thoes should be working probably and if thoes work you could try with others afterwards). That did the trick for me.

 

yeah tried it in safe mode a bunch of times but maybe i need to do the reg cleanup. It would install ok in safe mode but still result in low scores (1000+ lower)

 

do we have a bios update for the m860tu?

 

Try using the CCleaner to do the uninstall and the cleaning, works very good. Also, what operating system are we talking about? Vista 64 needs to be booted so that it doesn't enforce the driver signature thing, maybe your blue screen is coming when vista wants to tell you that you can't install the drivers because they are not signed?

 

actually that would come up and i could just continue it.... what i did was disable driver signing via cmd window....uninstalled in safe mode and ran CC after reboot in safe mode....then booted into windows and installed the drivers from xoticpc/sager's driver disc (176.02 i think?) then i noticed nero had a service using 50% of my cpu for no reason so i uninstalled nero.... end result - i ran 3Dmark06 to get a 10017 - right where it should be with my 600/1450/800 clocks not sure what did the trick but sweet! not feeling like messing with laptopvideo2go drivers now even though the 178.15 probably perform a bit better..

 

Latest bios is 1.00.07 and kbc/ec firmware is 1.00.06

 

tested the lptpv2go drivers and neither the 177.98 that worked really well before or the 178.15 performed better than the stock drivers...kinda odd imo.. oh well nothing wrong with the 176.02

 

I'm sticking with the stock drivers as well, haven't read a compelling argument for using the ones supplied by LV2Go in my 8660. I do use the 177.98 drivers in my Acer 5920 and they work ok, much better than the ones I had before that, which were just horrible.

 

The stock drivers were significantly laggier for me in games; latest run fine, as did 178.xx

 

im still wondering why i have to go through the whole safe-mode and registry cleaning hassle to install updated drivers when i didn't need to pre-format...and now the same drivers perform ~500 worse in 3dmark06 and more laggy than the stock drivers...what could cause this? any ideas?

 

The safe mode thingy and registry cleaning is just a precaution, to make sure there are no trace of the earlier driver, so it shouldn't make any troubles... You can do as you did before, but it may, in some cases lead to problems (driver versions using diffrent filenames for same job ect. leading to a conflict)... About the "lost" 500 points in 3dmark, is that the only program having a performance loss? Any other programs running in the background compared to before the reformat ??

 

well the thing is i'm doing nothing different than before and if i DON'T do the safe mode routine, it WILL bluescreen every time. No addition background programs no. Actually less, and i have all the vista extra garbage turned off (restore, shadow copy, firewall, indexing, etc.) Its weird how it won't accept a driver any other way and the drivers that ran so much smoother before no longer will..

 

Have you tried doing either a repair installation of _Vista or a second format/reinstallation?

 

Now testing crysis out i've found that things will be running ultra smooth and then randomly come to a slideshow for a few seconds.. Just a pain reinstalling all the programs and whatnot =/

 

No doubt, so I wasn't just suggesting it to be facetious. Before going all that way, have you checked to see if anything's showing up in your event logs, such as a warning or an information log regarding your GPU drivers, or any other driver (stuttering like this is almost certainly caused by a malfunctioning driver)?

Another utility you might try out is called DPC Latency Checker - it's a great little bit of freeware that can be used to try and pinpoint which processes on the system are suffering from significant delays in processing their deferred procedure calls ("DPCs").

 

when i try to update drivers it bluescreens when it gets to "restart now?" yadda yadda

yeah my log files are empty though, checked em everywhere

 

Ok, so my memory's not what it used to be - that's what happens when you hit geezerdom!

But, even so, it could be something not directly related to the drivers you're trying to install - it could be something that the drivers have to interface with that is itself not functioning correctly, and when the drivers try to establish that interface, the corrupted whatever-it-is causes them to lock, effectively freezing the system.

 

yes, my suspicion is that something didn't go quite right with the OS reinstall...

 

And that something might be throwing off other symptoms that just aren't bad enough to cause a freeze. Since it only happens when you try to install a driver, see if you can find the inf file or some sort of configuration file that is used to do the installation (I don't know if such a thing exists, I'm just thinking off the top of my head right now), and then see what the installation process monkeys around with as it's installing the driver - that might narrow down the possibilities of what's corrupted.

 

yeah did a complete partition format and clean reinstall...same bluescreening **** again when the screen comes back from being black displaying errors concerning the nvdsys or whatever the driver is....i don't understand how it's not working anymore..

 

what, precisely, was the name of the driver the error was triggering on? nvdsys.dll, nvd.sys, or something else?

 

nvdsys.dll - i solved the problem. Apparently the drivers didn't like my flashed vbios for OCing and some UVing...flashed to stock to upgrade drivers and it worked. Then i just flashed back after - seems fine now...how odd...
