Solved Computer Turning Itself Back On Almost Immediately After Shutdown

[BeKure]

This doesn't happen all the time but it does happen more than I would like it to. Sometimes after I shutdown my PC via the start button. It will turn itself back on after about 2-3 seconds. This is very annoying and I was wondering it anyone else had this issue or if anyone has even heard of this issue. Any help would be appreciated.
Thanks.

Well I have never had this problem but it would help if you filled in your System Spec's. It will help others help you.

I've seen this when PSU is on its way out. If you can't solve it any other way, then try swapping PSU with a known good one, to rule it out.
