Hello! I've been experiencing that my PC blacks out, while I'm playing games, for some years now. So after countlessly lots of troubleshooting, I'll ask for help: I'm using Windows XP Professional, vision 2002 with service pack 3. My computer contains: AMD Athlon 64 X2 Dual Core Processor 5600+ Radeon (Sapphire) X1950 Pro Graphic Card MSI K9A Platinum Mainboard 2.81 GHz 2GB RAM My problem looks like this: Whenever I play a game, that requires me to play in full-screen mode, there's a chance that my computer suddenly blacks out. Unlike Blue Screen of Death, I'm not informed about what caused it, nor what I should do. Usually the sound either continues, or begins to lag like an old CD-player, and my screen says "No signal input. Check video cable", but there's nothing wrong with the cables. I've noticed that old games(Diablo II, Warcraft III and the like) doesn't cause my personally Black Screen of Death, while newer games(Counter-Strike, Heroes of Might and Magic V, Prototype and the like) usually causes it. Oddly enough, Demigod haven't caused it yet, while games powered by Steam had a bad habit of causing it, which doesn't occur as often anymore. Prototype seem very fond of causing Black Screen of Death, for some reason. I've tried to update my graphic driver, but that didn't effect it at all. I'm aware that some of my drivers are out of date, but I've been unable to update them. Every time I attempt to update drivers, I'm nearly E-bombed with those crap-programs that scan your computer for out-of-date drivers, and then want you to pay for the program to update them. But driver or not: Any help?
