computer wont start after shutdown

[account_disabled]

Hi,

Ive got a weird problem where my computer wont start after i shutdown.

if i turn off the power at the power supply and then turn it on again before the motherboard light has gone out it still wont start. if i wait until the light has gone out and then turn on the power supply, then everything starts fine.

once it actually starts everything works perfectly. also all voltages and fans are fine.

if i shutdown and then turn on computer with case button within a few seconds then it will startup fine. however if i leave it off for a few minutes then it wont start unless i do turning off power supply as above.

ive checked it isnt the case by shorting the power pins on the motherboard to start the computer.

ive now unplugged optional stuff like extra hard drives and fans etc but that hasnt helped. i cant disconnect everything since otherwise i cant start windows to then shut it down to get the problem.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
