could you describe the problem in more detail? including complete system specs, how old it is, power supply rating
what have u already tried?
could be a problem as simple as damaged extension cable or as bad as damaged hardware(psu, mobo)
so i would go thru these steps:
change power socket in which computer is plugged in
change extension
change power cables
check power supply
last-motherboard/other hardware

If you're getting constant power, then it shouldn't have anything to do with the extension. But as undead has said, you need to give us proper details as this isn't enough. Your PC shuts down just as the Bios screen appears or windows loads, or something like that?
