i recently bought a new computer at a small pc shop. They build it for me. The processor is intel core duo e6600 the mtb is Asus p5b s775 memory 1 gig ddr2 667 Kingston with win xp and the box is Antec slk 1650 350w. The problem is that the computer has been crashing up since a few days. I'm running a program and then it stops without any warnings. I then wait a little then restart it and when i restart there's a message saying new CPU installed press f1 to configure or f2 to restart with default settings. What do you thing can cause this problem?
