PC with Intel DP55WG fails to start

[dezed]

Hello Experts,

I'm having problem with my PC.
The spec is:
MOBO: Intel DP55WG
Proc: Intel Core i5 760
VGA: Gigabyte GTX 560
Memory: Corsair 8GB

It was working fine the night before, and I shut it down normally.
Sadly when I tried to power it on this morning, it doesn't start. It only flash for about 0.01 second, and nothing happen.

Any idea what might be the problem.

Thanks.

Hello,

Sorry to bother you all. Apparently the problem is with the PSU, the other components are fine. Now I'm waiting for the replacement of my PSU.

Thanks.
