    If you haven't made any changes recently, then yeah, definately a psu prob.... if you have made changes recently however, make sure to recheck what you've done. Double check power connections on your motherboard, make sure the LED on your motherboard turns on, make sure the various cards mounted on your motherboard are affixed properly, etc etc.... but yeah, like 600 says, its most probably just yer psu that died or at least is on its way to the grave....
