PC turns off after few seconds after on button

This started about a month ago. Turned on PC and after 4 seconds or so, it turns off, then after about 8 seconds turns on again with no probs. I had an Asus suite and unistalled it. Same prob. CPU is running at 47deg Celcius so its not overheating. Could be a software issue? Im thinking of doing a clean W7 install.

Anything 4 seconds into the boot cycle is not even hitting windows yet, so ignore anything on the software side. It turns ON after 8 seconds by itself?

If it shuts off and you have to turn it on again after 8 seconds to get it running then it sounds like a power supply issue, it isn't providing enough power on the cold boot.

If the motherboard is shutting down after 4 seconds then powering itself back on 8 seconds later, the motherboard needs replacement.
