Computer repowers after shutdown

[xyber98]

I've seen a few threads out there regarding a computer repowering on its own. My computer repowers after shut down, SOMETIMES. I had one power supply go bad on me, and just replaced it with a brand new 480 watt antec. Since the new power supply in two weeks it has repowered 2 times, better, but I suppose it wasn't the power supply. The "Wake-on" features in my BIOS have been disabled. Im at a loss here guys, changed the power supply and checked my bios settings and still have the issue lingering. My system specs are MSI-neo4 Platinum, Asus Geforce 6800GT, WD Raptor HDD, 2 gigs OCZ Platinum ram, Athlon x2-4200 dual core. The computer is plugged into a power strip surge protector, NOT A UPS. I was thinking, could it possibly be bad power? Anyone have any idea?? Please help!
