Hi guys ive been trying to figure this out for days and its driving me nuts ok so the other day my video card stops working randomly after reboot its a 8600gts i plugged the VGA cable into the onboard port and got display, i thought it might have been fried so i pulled out the card and stuck it in another computer and it worked just fine, so i tried to take a video card out of another computer and tryed it in mine and it worked no problem i changed the video adapter settings in BIOS tryed drivers and clean reinstalled windows and still nothing its like my motherboard is ignoring the video card because other video cards work in my computer and the 8600gts works in other computers any ideas?

my computer is a HP m8000n MY PC

Hi mustang18
This may be a PSU issue, did the replacement card that you tried in your computer that worked need a separate power supply from the PSU, have you tried another power supply from the PSU to the present card?
What is the make and model of your PSU.

I agree with phillpower2.
If your card works perfectly in other computer and another card works fine in yours,
check the power requirements for each card.
The cards you swtch are both 8600GTS?

You can check the PS with a Power Supply Tester.
