When I play games (or any other video/graphics apps) about every 10-15 seconds my fps drop to zero for a second or two. I have tried adjustments of video quality and everything. I have all the current drivers and directx 9.0 installed, there are no other apps running when it happens or loads on my system. My friend has the same Nvidia card and has no probs with his, running same games etc. Is there something I need to do to fix this? I'd hate to have to go buy another video card though I'd love another one. Specs are down below. HELP
