My very good friend has been having consistent problems with his computer since his last upgrade (about a year ago). His computer runs fine 90% of the time but sometimes it just freezes on him for no apparent reason. I THINK it has something to do with his power supply. From what he told me it was a 250W generic. He has an AMD 1200, 2 hard drives, a G4 Ti420 and some other random stuff I cant specify. I told him to get a new PS but he thinks im full of crap. Is it possible that Im wrong?
