Ok so I have been randomly having FPS issues when I play World of Warcraft. It's fine one minute and then I come back and its choppy as hell. I thought that it was WoW related so I did everything I could possibly do which included deleting a lot of stuff and updating my drivers. Still.....the problem continued. The only way to fix it is to restart my computer then everything is fine...at least for awhile. Today it started to do it when I was watching movies on my PC. So now I know it has nothing to do with WoW and everything to do with the video card. But like I said I have uploaded new drivers countless times and it's only 3 months old. I don't know what else to do and I need some help here. System info is below........
AMD Phenom II x4 965 Black Edition
16GM RAM DDR3
NVIDIA GeForce GTX 550ti
