Hi guys. Well I'm running my sig rig with 2 GTX 680s (Palit and EVGA) with no issues till a while ago. Basically I was playing AC3 when suddenly my computer crashed. I rebooted and found that everything seemed okay so I then proceeded to start AC3 again but then my computer crashed again so another reset had to be made. After the reset, my computer hanged on desktop so I though then maybe I just reinstall my graphics drivers which I did through safe mode. After reinstalling the drivers and booting my computer normally, low and behold only my EVGA card was being detected. Rebooted the computer and still the same result. Checked BIOS and found that the board wasn't detecting anything on the 2nd PCI-E slot (Slot where Palit is installed). Next I opened up the computer and took out the EVGA and placed the Palit on the top slot to try it single card, board did not detect the card still and runs on integrated. I know it's running integrated because when I plugged the DVI to integrated the display showed up. I also took an eraser and cleaned the copper on the Palit but still the same result. The card does light up and all the fans are running so I know there is power going to the card. My card's BIOS isn't modded so I only run my overclock at the stock 1.175v allowed and it's also been running on the same overclock for more than a year now (1228/6900).

Does anyone have any idea on what could cause this? Currently I'm lending it to a friend to try on his rig to see if he can get it to work but it looks like it suddenly died for some reason. Could my overclock have caused this? My PSU is a Seasonic M12II 850W so I would hope that it isn't responsible for damaging my card in any way..
