Hello all,

Just recently my video card (Gigabyte HD 7750) has started to cut out while playing the Witcher 2, but I've not had issues playing any other games. I see similar symptoms while running Uningine's Valley benchmark to test the card, but have no problems running the Furmark benchmark.

The computer is hooked up to my plasma TV via HDMI and when the lock up happens, the display goes black and it tells me the signal has been lost. The entire computer is definitely locking up and not just the video card cutting out. Similarly, the case, CPU, and graphics card fans all continue to blow after it locks up.

I just put in a new 600W Corsair PSU, have tested multiple sticks of new RAM, and tried multiple different versions of drivers.

Is there anything else I can test before I try to RMA this with Gigabyte?

Thanks in advance for any help offered!
