My Toshiba Satellite running XP started crashing (black screen) recently after an average of about 10 minutes from boot. No problems if running in safe mode. I reformatted my hard drive and reloaded XP thinking that I had a corrupt Windows file causing the problem......BUT, the problem still exists. Right now, I have not loaded anything else except Windows on the machine and it's going to black screen after running a few minutes. Any suggestions on what might be causing this?
