hello there, I just recently bought a 5870 for the brand new computer I built. First day everything was running fine then second day I noticed that the screen would randomly go blank and then reappear normal as if nothing happened. I got no messages from windows nor any hiccups on the system itself. The power didn't cut off or anything. It just blanked out and came back. Then today it started to happen practically all the time, but thing is it only happened when Firefox and utorrent windows up. If I minimized everything to the desktop then it would not happen. If I played Windows Media Player it would work fine. I figured it was the video card but I"m curious as to what you guys think.
