Dimension 4600 keeps powering itself up

My new Dimension 4600 keeps powering itself up having been plugged into the mains for about 5-10 seconds. First the fan comes on fr about 2 seconds, then 5 seconds later, the PC boots up. The 'AC power recovery' BIOS setting is off, and there are no network/modem cables plugged in. After its been powered down (either by shutting down from Windows or by using the power switch) it stays off for about 5-10 seconds, then powers up again. Any ideas?

    Probably a motherboard problem but could be the power supply.  Contact Dell for warranty work.

    Recommend the e-mail tech support instead of calling if you can.
