But given the age of the card it's not expected to be working today. It's that old.
Hello!
I just second-hand purchased an EVGA 8800GTX 768MB, upgrading from an EVGA 8600GT 512MB. I installed, plugged both of the PCI-E connectors into the card, and tried to turn on the computer but it didn't work. At first, I got a fuzzy start-up screen and then it went all black. I restarted and now no signal is being sent to the monitor.The BIOS doesn't beep at all. I tried using only one of the DVI slots and plugged it into the VGA end of a TV monitor and the image worked but it was terrible quality. I tried reinstalling and no signal was sent again when using both DVI slots to my monitor.
I put my 8600GT back in and it worked fine, with no problems. The seller has been very responsive and assured me the card worked, so I trust him. He's also willing to give me a refund.
I believe this card should work with my machine, but is there a problem with this specific card?
Some pictures from the start-up when only using one DVI-to-VGA TV monitor pictures:
