Hello, I built my computer a few months ago (AMD 3000+ 1.8ghz, 80gb IDE HDD, 34gb SATA Raptor HDD, Geforce 6800 128mb AGP, 1gb (4, 256 sticks of same ram) and a 550W PSU). Recently when I start up a gaming application like Half-life 2 the computer restarts after a few minutes of playing. I read the error report and it said it was a Nvidia corporation driver problem. The forums their said to DL the 71.89 (April 14, 2005) drivers. So I did and it screwed up my computer where i could not get to the desktop or login screen. So I reformated and a few minutes into the desktop, I was installing motherboard drivers IT RESTARTED AGAIN. Please help, what is going on?!
