That's a clue. Not much of one but as I read posts about this board such as http://www.tomshardware.com/answers/id-1669935/motherboard-bios-recognize-evga-gtx-660-card.html I begin to wonder if it's just not a very good board.
Try another if the BIOS settings they noted do not help.

I came out of sleep mode a few days ago and there was no signal to my monitor. Monitor and HDMI cable are fine so i used a DVI cable straight from the motherboard, which worked. At this point I assumed that there was something wrong with my video card but when i got into windows, windows said it wasnt a genuine copy. At this point i thought maybe it was a virus even though i have Kaspersky so i did a fresh install of windows 7 and then attempted to reinstall my video drivers but that was difficult because windows kept crashing. Finally get the video drivers up and windows does not recognize that the card is there. The fan on the video card was running so i knew it was getting power. At this point i moved the video card to the other slot and it worked, However, now i cant be in windows for more than a few minutes, if that, before it crashes, or more accurately, completely freezes. I have tested the ram with memtest and also tested the hard drive and the video card seems to work fine in the other slot, so I am wondering if this is definitely the motherboard failing. I took the whole computer apart and cleaned it and put it back together thinking there could be a piece of metal somewhere shorting it or too much dust buildup but when i put it all back together and booted up, once again the video card didnt work in the first slot and windows crashed almost immediately. All my components are 2 years old and have never had any problems.So i am wondering if it is definitely the motherboard. It is an ASUS p8b75-v. Please let me know if any of you can help or this sounds familiar. I dont want to buy a new motherboard unless i know for sure.
