    Is this a desktop over 3 years old?
    Is it running Windows XP? Vista? Any error messages?

    Most likely hardware issue is a fan has stopped working. The will stop a PC is less that a couple of minuets.

        i removed the processor fan and found the processor very hot , is it normal or there's a problem with the cooling ?

        Also if it's a power supply , it wont power on in the first place right ?

        Power supplies don't always just die - they often start to go bad with different symptoms - including the one you're describing.

          Just make sure you get it from a retailer who will take it back if you don't need it.

            Two more things to check.

            1. A failing floppy drive or a failing CD-drive could also cause the symptoms.

            2. Judging by your comments, the CPU may have lost intimacy with the heat sink. Check and see if the heat compound has dried up or  caked. In six years it  could happen.

              That's what I mean. Make sure is is seated right. Heat transfer is very important with modern CPUs.
