BSOD?

[galdoes16]

My brother in law just got an dell XPS 420, with a q6600, 8800GTX, 4gb ram, and a 500gb hdd. He is getting BSOD's almost every day.

I did notice that it came with an 420w PSU, could this be the culprit?

Without knowing what the stop errors are there is no way anyone is going to be able to offer much help. Have him write the error numbers down and post them here and we can probably point you in the right direction....
