Boot require power supply reset

[ppopops]

Hi,

To boot my computer, I must turn off my power supply for a few seconds and then turn it back on. After that, my computer works without any problems. If i don't reset my PS, the computer won't even post.

Specs:

AMD 64 3000+ Venice
Chaintech VNF4 ultra (nforce4)
1gb DDR Corsair Value
Evga 6600gt pci-e
Antec Sonata II W/ 450W smartpower
Seagate 80Gb 7200.7
SB live
no OC done

The problem suddenly happened. One day I just couldn't boot the computer and had to reset the PS for it to work.

Anybody knows how can I fix this?

Try clearing the CMOS per the MB manual instructions.
