yesterday i was normaly on my PC then...if turns off and i hear a small bang from my 400W PSU.
it didnt turn on... i waited abour 20 minutes it turn on...and then when i was loggin in windows it turned off again.
i had to wait until today for it to work again.
replaced the power suply to a 350W backup one and it was alive again!!!
tested a few times by turning on and off.
it entered windows again and went down....and now i cant turn it on again...

i dont know what to do next...is it the board? please help me!

A bang... sounds like you either lost a fan blade or poped a cap.

Try a different powerboard if your using one..and then a different power outlet if it still occurs.

If that doesnt highlight the problem check the motherboard for burn marks..perhaps it was a capacitor that blew??

Sounds like maybe the PSU blew and took your mobo with it.

Like Nonchalant said, look around on the board for burn marks or blown or leaking capacitors.
