So last night I was in bed with my girlfriend and my pc randomly turned on. Then it turned off then on then off again. It kept doing that until I went and turned it off at the PSU. Got home from work today and its still doing it. Sounds like a faulty PSU? I can't think of anything else being the problem since the PC was not turned on when this first started. I have reseated every connection taken out and put back in the CMOS battery. Unplugged my GPU and WiFi card ram and HDD made sure my reset button was properly plugged in. If I switch it on at the PSU now it just turns on for a few seconds then turns off and repeats over and over and over again. Any ideas guys?

Have you tried starting with only 1 ram stick in? Typically restart cycling is from RAM, the next guess would be PSU. Everytime I've wanted to point to the PSU though it's ended up being RAM.

Yup just took each stick out made no difference. Don't see how ram can cause the PSU to deliever full wattage though. I am trying to figure out if Somthing is tripping my PSU. Any other thoughts?
