Now I believe this might be a video card problem. Which I am hoping because I just bought it. Anyway for some reason. I'll just be browsing the internet or something, and my screen will just go out. The green LED on my monitor will switch from green to red. Which means there's no video going to it. I then always have to reboot. Does anyone know what I can do for this to stop? I'm running a Pentium 4 with 3ghz, 1.5 GB of RAM. And my video card is a Nvidia 6800 XT. Any help would be appricated.
