OC gpu ruin mobo : /

[jiffy]

Hi all, I OC my 8800 GT card and then it froze and BSOD during boot ups. I reinstalled Win and got rid of the BSOD, but now it's not recognizing the gpu at all. I even tried a 560 card and it did the same thing. I tried everything I could think of and it seems to me there is something wrong with the mobo. What else could it be? Thanks

Stupid question, but after you reinstalled Windows, did you reinstall the video drivers?

Yeah thanks I tried, but I got errors and that is when I realized the gpu's weren't being recognized during the boot up. Usually WinXP will give it a default driver and then I can update the driver, but now it doesn't recognize it to update it.

I'm putting a new pc together soon and will have a new cpu/mobo and figure I'd take this one around the block one last time, but I wasn't thinking literally.
