PC Standby problem

[Nerevarine]

My friend's PC automatically goes to Standby mode, when running for a while (even when it is not inactive).. I have checkd the power management settings etc but the problem still persists..
The complete specs :-
Core2Duo
2GB RAM
El-cheapo Zebronics PSU (This might be the cause but i still doubt it)

Thanx in advance

Could be an overheating isuue or it may even be a case of bad keyboard.
Worst case(chances are very less): Problem with motherboard.

does the pc wake up successfully from the hibernate or do you have to force a reboot?
When it enters the sleep does the front panel light blink(S1 state) or every gone goes to sleep(S3 state)?
