Computer turns on then turns off?

[Sarian121]

Last night after I was done using my computer I shut it down and went to bed. I wake up this morning to find that when i push the button, the everything turns on for half a second and then turns off. Ive checked all the connections and everything seems fine. I tried turning off the power supply and turning it back on again but it still does the same thing.

Any suggestions?

reset bios, then flash it

PSU has always been my problem in cases like that. What is the PSU and your computers specs? It could possibly be the power button also. Post your specs and we will go from there.
