PC boots randomly and restarts on shutdown

Recently I have been having a few problems with my system rebooting on shutdown, and the only way to turn it off was to flick the switch on the back of the psu. This has then got worse, when I come to boot the pc up next time, it doesnt respond to the power button at all, but then randomly a few minutes later it boots up :O.

Ive been using this computer for nearly 2 years now with no problems, and no hardware changes so have no idea whats wrong. Have tried using a different power switch to see if that was broken, and its made no difference.

If its any help I'm using an Abit AN8 motherboard, and the little POST code display on it shows "0.0" when the pc is first turned on, and changes to "F. " when you press the switch (Fail I guess?).

Thanks for any ideas in advance

I dont think it will be the PSU, as when it does boot up it runs fine, can browse the web/game/play music no problem. And nope, I dont have another PSU to test it with

Hmm ok thanks for the replies, I'll try and get another PSU to test it with :O

Hmm ok, have tried a different PSU, but same problem still

Have left a few things unconnected so there less load on it but no effect, any other idea's?
