I have a problem with my computer shutting down on it's own. It acts like a restart, but i can hear the harddrive slow down til the power kicks back in. I just replaced the power supply with a Antec 350w. I thought i had it fixed, but it is still doing it. Does anyone know what the problem could be? I have an Abit m/b, AMD Athlon 2000xp processor, Maxtor 40gb, Sony cd-rom and burner, ATI Radeon 8500 128mb video card, PCI512 Sound Blaster, Antec 350w power supply(brand new), Windows XP Pro. Any ideas on what else it could be?
