My son's computer is dying.
It locked up suddenly yesterday while he was browsing the PBS Kids website, which he has done countless number of times. Nothing would revive the computer from its frozen state, so my wife had to do a cold boot.
It took a long time before booting, but it never booted up to even the BIOS screen. The power would come on, with the fans whirling and the lights coming on in the case, but only for 3-5 seconds. Then it would power off on its own, and a few seconds later, the power would cycle on again on its own.
It would keep cycling like this forever until I kept the power button on the case depressed to manually power down the computer.
I thought for sure it's a problem with a dying PSU, so I got a new PSU. I built this system in 2008, so it's been many years after all. I replaced the PSU this evening, and the problem persisted.
Does it mean that I have a dying motherboard?
