It's usuallly going to be the PSU, motherboard or both. But check my # 2 here for some things to check that I've run across previously:

That person's problem wasn't exactly the same as yours but the testing procedure is the same.

If you have disconnected the molex connectors from the motherboard and your power supply fans stay on, then it sounds like you power supply has failed.

You shouldn't be yanking power connections from the motherboard when it's running.

You say it shuts off during boot up. By 'boot up' do you mean it shows the emachine logo or posting screen and maybe starts booting into windows or do you mean you hear the fans and drives spinning up but nothing shows on the screen and then it shuts off?

Did anything happen to it or did you make any changes between the last time it worked OK and the first time it didn't?

It wont even turn on for two seconds ,I press the button and you hear the fans turn on then it shuts off. I disconnected the molex cable while the machine was powered off . Then i started it up and the fans stayed on. Nothing happen to the machine like power surge. It dosent stay on long enough to see post screen
