Video Cards Keep Dying

[Vyx]

Cross posting from [H]. Please help!

Original Post Short version: I went through 4 EVGA 8800 GTX RMAs. Video Cards kept dying. Most thought it was either a PSU or Mobo issue.

Current:
I got a new 750w XFX power supply as well as a working motherboard from a friend. I swaped everything over and proceeded to instally my 5th EVGA RMA 8800 GTX. Also did a clean install of Windows 7.

Everything seemed to be going alright for a few days. Then, I started getting the white screen in BF:BC2. This happened a few times and then the video card just died. It stoped showing any video. I swaped in another temp card to make sure the motherboard was fine and it booted up just fine. I put the 8800 back in and no dice. It was dead.

I talked to EVGA and got them to send me a different card (GT260 I think). Anyhow, anyone know WTF might be going on? I don't want to kill this card too. I don't even know what could possibly be killing a video card besides the PSU and Mobo.

Thanks for any advise,
Vyx

Not having read through your other thread, have you thought about investing in a battery backup (UPS)? That should eliminate any chance that it's your incoming power that's the culprit.

Also, try using a different VGA or DVI cable. Maybe there's a short in it somewhere.

Monitor feedback? Cooling issues? I'd lean toward the latter, but the former would (oddly) be an issue.

As far as a UPS, would this be sufficient? My PSU is 750w and I know that it's not always pulling that much but...

8800GTXs dying is not uncommon is it? Searching on google brought up a bunch of threads, and people trying to fix it with the baking method.

AFAIK, you don't need a huge UPS if all you want to do is clean up your incoming power. Even a small UPS will have enough capacity to bring a momentary power dip back up. All a larger capacity UPS will give you is increased running time during a power outage, which isn't the reason you're contemplating purchasing one.

Alright, thanks. I'll grab a UPS and a new DVI cable.

Cooling shouldn't be an issue because I'm running this in an Antec P182 and all the cabling is run behind the motherboard.
