    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

    photo 1
    photo 2
    photo 3
    photo 4
    photo 5




    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?

    Yeah at this time I installed HD4670 every thing works fine even onboard video card works great. but when I installed 9400GT Computer will not post. I was try it with Antec EA-750 Green.

    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.

    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.

    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

    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.
