Hi all :)

My Computer will not post when I installed EVGA 9400GT 1GB in the PCI-E slot

the problem start when I change GPU thermal. So when I run computer "windows welcome screen" freezing with blue color, then System failed. I was tried to fix it but I give up. There is no physical damage.

Anyone can diagnosis this problem ? is that capacitor problem ?
I can upload photo for the card



There is no physical damage : have look at photo

Thanks in Adv :respect:

To assist with others, this is the motherboard http://www.findlaptopdriver.com/pegatron-2a94h-motherboard-specs-3272011h24/

I see the motherboard has an onboard vga. Try to boot with the gfx uninstalled using the onboard video. That will at least rule out any other possible issues (unless it is related to the power supply).

EDIT: I see in your system specs you have an ATI card. I assume you are removing that when you plug in the Nvidia 9400 card?

Perhaps this is the problem, I mean you said it yourself that this happened after applying some fresh thermal compound on the GPU. For the time-being, check the thermal compound whether it's applied too thickly on the GPU, and check whether the VGA cooler's heatsink is really touching the GPU core; the heatsink needs to make proper contact with GPU core, otherwise you will get into problem due to overheat etc.. Furthermore, also check whether the VGA cooler's fan is actually spinning, otherwise replace the VGA cooler + fan if the fan is dead.

Sounds like bad memory on the 9400.

Yes, this problem happen when I put some thermal ***** Fake Thermal :shadedshu *****
So I replace it again to Arctic Silver 5 but I can't make it work.

Make sure that the heatsink is making contact with the memory using thermal pads. You don't want to use conductive thermal pastes (such as Arctic Silver 5) on memory chips as you run the risk of bridging the chips and shorting them out. Generally you need thermal pads though to make up the space difference between the heatsink and memory chips.

did you remove the drivers first before you removed the 4670 physically?

Run Mem test on the ram, check the caps on the motherboard. Even Clear CMOS might help. Even reseating the card too

http://answers.microsoft.com/en-us/...db?msgId=e363c992-3a64-4367-8220-0ce9b12f99a8
There is no driver was when I installed 9400GT,

I can't make PC work when I install this card. Even PSU didn't give any power :confused:

I think maybe capacitor. I will upload a photo as soon as possible

Use an eraser to clean the contacts on both sides of the GPU, Make sure to "Seat" the card good!
I remember doing this with Game Carts lmao

try to boot using onboard graphic card first then reboot and set it into your current card
then turn off and plug in your card

from the card it looks OK but you need to make sure that the card working perfectly, you may test it on other pc first

Yes, the GPU is dead, and it is not worth trying to repair it either.
