EVGA 8800GTX Installation Trouble

by jmopc7226 / September 29, 2015 8:09 AM PDT


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:

Windows 7
Gigabyte GA-P35-DS3L LGA 775 Intel P35 ATX Intel
Thermaltake W0131RU 850 W ATX12V
3.16 GHz Intel Core 2 Duo E8500
2x1GB A-Tech DDR2 (800 MHz)
2x1 GB Patriot Extreme Performance (800 MHz)
160 GB Western Digital Caviar SE WD1600AAJS

Thanks in advance for any help!

Thanks, Proffitt for responding! I used the PCIE connectors that come out of the PSU w/ the ATX cables. Should I try to disconnect them (although they're internally connected) and plug them into the 1st and 3rd rail? Or are those two already providing ample power?

Thanks again!

I can't decode what you asked. But looking at the PSU's spec I see the 2nd rail is 18 Amperes which fails the card's 30 Ampere requirement. So if you can change rails, that's what to try next.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
