My other computer is starting then shutting down within two to three seconds after starting and shows no signs of even having time to try and boot.

Any ideas what's going on?

I've just fixed the same problem on 2 (!!!) boxes

1. Reset BIOS by take out/put back a battery
2. Replaced case start button (not power supply). You can check it by doing the following:

a. Open computer and find a wire that goes from a case start button to motherboard.
b. Power on the computer and pull out the wire that you found in step 'a'
c. The computer starts up
thank you for helping me reset bios.
Sometime componenet failures also cause the problem. In my case I had CD-ROM issue, it was not working properly, I removed power and data cable. It starts working normally.
