I have an ANTEC PP-303XP power supply. From day one (roughly 3 years ago) my computer randomly freezes. It doesnt matter if it is idle, or if i am gaming, this thing will randomly freeze, and the time is never the same, sometimes I can be idle for 3 minutes, other times it will be three hours. I first experienced this on a FIC AZ11EA motherboard with a 1.4ghz athlon t-bird. I have tried different motherboards and processor combinations. But the random locking up still occurs. Could the lock-ups be caused by the power supply? It is a 300w by the way. Any help is appreciated.
