I did upgrade my laptop'c CPU and...

Hi, i have an XPS M1530 and which cam with an Intel Core 2 Duo T7250; 35W TDP, 1.075V-1.175V.

Then a few days ago i bought an Intel Core 2 Extreme x7900; 44W TDP, 1.125V-1.325V.

The first thing i noticed is that the temperatures were to HIGH! 95°C peak (playing)... so i did get a "temporary" cooling pad, which keeps temperatures under 80°C (not bad).

But the main problem is that modern games like Batman: Arkham Asylum, or Need for speed Shift, runs worst now, i mean i am suffering horrible fps drops each let said 10 seconds i get a fps drop.

Then i did the Stability test from NVIDIA's control panel, first i tested only gpu, and no problem, gpu+PCIe bus, and no problem, GPU+PCIe bus+ HDD and no problem, GPU+PCIe bus+HHD+ CPU and i did get some frame drops... then i tested GPU+PCIe bus+HHD+ memory and i did get some frame drops...
finally i testes all components and was horrible... i only get like 1fps each iteration of monsters frame (if you know how the stability test is)...

While the test was running the temperatures were fine always under 80°C both CPU and GPU, watching Everest.

So what the problem could be?

I hope you can help me guys....

regards to everybody

 

It sounds like a standard case of too high temps. This causes downclocking of GPU and hence the stuttering.

 

You think everes is reading the temperatures wrong? becauses GPU's temperature during the test was always under 70°C and CPU always under 80°C... what could make everest read the temperatures wrong?

 

try hw monitor it is more accurate.what is the temperture of your hdd usually?
it is possible that everest can read temps wrong,in my opinion hw monitor is better.

it is really a confusing problem.does your lappy run in expected(normal) performance while in windows?.maybe your hdd is really full.try to clean it.use ccleaner and do hdd defragment.

when you did the gpu upgrade did you increased the graphics?try the default or lower ones.

 

Well HW monitor is near to Everest the time i did check it.. the HDD temperature was around 30ºC... and the i have like 3GB free in HDD...

But thats not new, before with the old cpu i always worked with that amount of free HDD and no problem..
and it seems to be something with the 3d app becauses windows runs well..


LAST NEWS: something terrible has just happen!!! i decided to change the thermal paste again (both GPU and CPU) and now the laptop's monitor doesn't show anything, no bios start, no first screen, just a big black screen !!!!! i decided to go back to my old CPU and the problem is still there!! but i can listen how windows start.... only ear

What have i done WRONG?!!! i just cleaned the GPU and CPU with isopropilic alcohol and put again the new thermal past... and nothing... the monitor doesn't show anything!!!!!!

 

It could be a bad GPU. Try plugging into an external monitor and see if anything shows up.

 

You can hear windows starting but you don't have video? Plug your laptop into an external monitor and make sure you can get video out that way... you might have just unplugged your video cable accidentally... it happens. If you don't get video out to a monitor you might have done a bit of damage.

 

Or... all that extra heat could have sent your 8600M GT to the land of all the other heat prone defective 8600s. Just a guess though.

 

Ok, i will try that tomorrow, but i dont get it...!! i just cleaned the GPU i didn't punish it or something wrong... and i cant see any video cable from the side i change the CPU... i dont know what happened...

 

It may be happened... but is just too much coincidence that the monitor went black just after changing the thermal paste

 

I don't understand one bit, can you hear the HDD work as if it's booting windows?

If not, try this:
1. Put the original CPU back in.
2. with battery and power cord unplugged, hold the power button for 30 secs.

then try to start it again.

For some reason when I put my CPU in a bad motherboad, and then put it back in my good motherboard it did pretty much what you just explained (black screen).

Then I did the power button thing and it worked the next time I tried it.

Something was probably wrong with the new CPU.
Check all of it's pins.
Maybe you want to get your money back on that CPU and buy another one?

 

The only other thing that comes to mind, and it might not even be applicable to your GPU, is that on mine (a lowly x3100) there are some transistors (or something, I don't know) that surround the silicon wafer on the GPU. If your GPU has a similar setup, are you sure that there is no material that could be in there shorting them out?

 

The impression that I got was that he could hear it booting into Windows (i.e. he could here the chimes as Windows started). If this is the case I would say that the CPU is probably fine and the problem lies somewhere between the PCB and the LCD.

 

Are you sure you got the GPU seated correctly after changing the thermal paste? It would make sense that you aren't receiving any image if the GPU isn't properly connected, and that would be compatible the hard drive and CPU still working and Windows at least beginning to start up.

It isn't clear to us whether your Windows is starting up all the way or not. The hard drive obviously is working, but is Windows booting up all the way, with sound playing et. al.?

 

since there is sound and windows is booting and makes sound,you have only a problem about graphics.forget other things and only focus on graphics to investigate what is wrong.some thermal paste dont conduct electricity so if you applied it in pins or stuff like metals etc. your gpu wont work in my opinion.you should have applied the thermal paste only to the top of your gpu(black or silver area) if you didnt

 

Hi, thanks for the reply. In fact i can hear how windows start, i can hear when the windows logo seems to apear and in fact i can start sesion becauses the fingerprint.

Hi, thanks for the reply. In my computer the GPU in not removable so, i am sure it is well connected. and YES windows is starting, in fact i did plug an external monitor and i can see everything.... i can see what i supose to see.. i mean i can see exactly as windows actually acts.

thanks for reply...Well.... yes.... it is a graphic problem but, the GPU seems to work through an external monitor i can see everything, my personal theory is that i unpluggeg the internal monitor cable... but i dont know how!!!!!! and i dont know how to connecting back

 

Hi thanks for your advice... i did in fact connected the laptop to an external monitor and i could see the GPU working... so as you said i did probably disconnected the LCD cable... but i dont know where the cable is or how connect it back....

Check out steps 10 and 11. They show the place where the display connects to the motherboard on the M1530.

 

Thanks for reply. Yes i did disassembly the keyboard and noticed the display cable was well connected.. so i dont know. I do have two theorys

one) the monitor did burn out

two) the motherboard did failed.

Boths theorys requires i try to contact dell and pay them for repair my laptop.. becauses my guaranty expired already besides i put my hands inside the laptop that make the guaranty void too.

 

oh,what a bad thing that happened.I am sorry for you.but you had a eye opening experience

you could have gave the laptop to a person that has a good experience.

please post when you find the problem.

 

So if you hold a flashlight to the screen, do you see anything? With no external monitor attached.

 

Well. i thought that changing thermal past was such an easy thing to do. Aparently i was wrong...

Talking to dell people they say they can't help me.... aparently there is not a dell's technical service here in Chile where you can pay them to fix your computer... they only work with guaranted hardware. so i need to find an external technical service.

I can't see a damn thing....the monitor is totally off... but something weird happened today, while i was using an external monitor i noticed that when i close then open the monitor display then windows acts if it recognizes my monitor (but in name only) still no image in the display but in NVIDIA CP it says i have two monitors... something like internal laptop's display and generic display.... so thats even weird becauses only happens when i close the laptops's display

 

If you're working on an external monitor, it's not the GPU. Take the system apart. Double and triple check all connections to the monitor (where the cable connects the the board, where it connects on the back of the LCD) and check for breaks in the cable.
Does the backlight on the screen come on?
Your temps are high (too high) but I'm not convinced that this is related.

 

Yup its quite weird if your montior dies even if your CPU overheats.. must be a loose connector cable..

 

Hi, thanks for reply. I did check the monitor connection yesterday again. And i can't see where the cable could be disconnected... i am afraid that the motherboard in the exactly point where the LCD connects to the GPU could be damage, thats one of my biggest theorys.

And to me the temps of the CPU/GPU aren't too high, always under 80°C which is a good temperature for a laptop.

that's an option but it is as you said too weird becauses i didn't make anything to the side of the motherboard connects the display to the GPU.

 

Does the LCD's backlight turn on? You didn't answer that.

 

Hi, i am sorry i did confuse your question. And NO the answer is no.. the backlight is off too..... is something like if the power suply of the laptop display were off.. is actually pretty weird i don't know what the hell it is.. so yesterday i sent my computer to "the guy".. so i think the will tell me i must change the motherboard which is really expensive.. and i will have to pay him to tell me something i already know and i will finally get an external VGA screen and use my laptop as a desktop computer =/

 

You might have blown an inverter in your LCD screen.. doubt that its a motherboard problem.. after all everything else like your CPU and GPU in your motherboard is working and you can log on and use your laptop with an external monitor..

 

Not the inverter, that was the point of the flashlight. The LCD would still be displaying things, it just wouldn't be lighted up.
It's likely the LCD cable/connection.

 

Well. i am not saying that the motherboard is completly ruined. I am thinking is ruined just in the point where the GPU connects to the LCD maybe one little line of the circuit is cut and thats enough to make the LCD not working (if that little line is the power source specially)...... but it is kind of weird... i am not sure is that is totally probable giving the circunstances...

Otherwise we know that something weird is happeningto the connection between the LCD and the motherborad becauses when i close the laptop's display in the NVIDIA control panel appears a seconds screen called "laptop's screen".. but i still got no image in the LCD but in that moment the computer recognizes the LCD... thats even weird otherwise the computer does not detect the LCD and only detect the external display...

 

Did you put fresh thermal compound on both the CPU and GPU?

 

Yes i did....

 

well.. talking to "the guy" he said i need to replace both the LCD and the LCD inverter..... but i am not really sure if thats the solution... i mean how is possible that changing the CPU i damaged the LCD and the inverter.... so i am afraid that i will expend money buying the lcd and the inverter and getting no solution, i think the problem is the motherboard... thats my thought....

Finally i did get an external monitor.. so i am using my laptop as a desktop computer.
