new monitor problem

[chuckywang]

Hey. I recently purchased a 17'' Smart Modular Pyxscape LCD monitor from buy.com. When it came, it was everything I expected it to be. However, recently, when I start playing graphics intensive games (or anything graphics intensive), the monitor just goes out. The computer is still running, I can still hear the sounds from the game, but the monitor just doesn't display what it should display (instead, it displays some sort of fading out effect, i can't really describe it). I have to unplug the monitor and plug it back in to fix this problem. I also noticed that during startup, the montor flinches when I BIOS or Windows XP starts up. Why does the monitor to this? Has anyone ever received this problem and know how to fix it? Any help would be greatly appreciated. Thanks!
