I was given this computer as a gift. When testing it everything operated normally until I tried to shut it down. It would shutdown for 5 seconds and then immediately boot back up. I thought the culprit was a dead cmos battery, but when I replace it the machine does not boot at all. The light behind the PSU is lit green as well. So when I remove the cmos battery, the machine boots up, but I can’t shut it down as it starts back up. Could it possibly be a bad motherboard?

I don’t see any burn marks on the board. I’ve unplugged all the connectors except for the 24 pin and cpu 4 pin and it still happens. I’ve noticed that when I plug it into an outlet it makes a little spark. Once I take out the battery it doesn’t do that and it starts to boot. But then the issue becomes “why won’t the pc shutdown” I guess I will just have to unplug it every time I shutdown. So I’m thinking the motherboard is shorted?
