I'm going to need more information to tell for sure, but I do have a few
possibilities. First, you have a faulty power supply. Personally I think
that the power supply is the most overlooked component in the computer
system. Second you could have a fault with your mainboard. Third is a
possible virus on your system. Since you are saying that it shuts off after
20 seconds I am thinking that the system may be trying to boot off the hard
drive. A boot sector virus could in theory at least give the ACPI command
to shut down the system. There are a few others.

Okay, the questions to help you further, additional info is in parenthesis
and brackets when needed:
-Is there any display on the monitor? (To see how far POST makes it and to
see if video chipset is operational.
-Is there anything odd being displayed on the monitor when your system
starts booting from the hard disk (if it reaches that far)?
-Did you add any new hardware or software lately? (Standard Computer
troubleshooting Question)
-Is there a floppy in the floppy drive? (If present)
-Are there any USB storage devices connected? (floppies, flash drives, card
readers with cards inserted [including internal units], hard drives, etc)
-Was their any other unusual happenings? (Standard Electronics
Troubleshooting question, helps with computers as well)
