Hello tom's hardware forums. I have a very irritating problem with my GPU. Every time I run 3D applications such as games, usually 10-20 minutes later I get a lockup of about 6 seconds and it'll work fine again. I currently have a HD 6870 and I used to have a HD 5770. The 5770 also had this problem too. I checked my RAM and CPU and they are working fine. Oddly, this problem doesn't occur on Battlefield 3, but occurs on every other game. I don't know what's going on.
