computer won't start
I was playing a game when the screen got full of artifacs and the computer locked up. I restarted the computer, but only got artifacts and then a crash.
I reinserted the graficcard (manual sayd I should) and it worked for 10min, then it crashed again. I got a nvida geforce 6800 graficcard. I can´t give much more specs since I can't turn on the computer. And since I get the screen full of artifacts as soon as I turn it on, I can't reinstal drivers or anything.
