I recently got a HD6850 and a Phenom II x4 from newegg.com. I installed them and it was all fine until yesterday. I was playing COD Black Ops and my computer did a weird graphic thing like a billion little frames out of place and then I got a blue screen and my computer did an automatic restart. It was working fine until today when I started playing COD again 15 minutes into the game the same weird graphical effect happen. But instead of a blue screen the computer just did a restart again but when the motherboard image pop up instead of been its normal color green it was a weird color like white and yellow. This is the reason why I think the graphics card is not working right.
Also I'm also worried it might be the new CPU but it only happens during games and always a graphics glitch. So what do you guys thing it is and what should I do about it.
