Computer problem- shuts down erratically minutes within booting up
So the other day my PC started acting up. Everything runs very slowly, and usually it will power down suddenly within a few minutes of booting it up, then after being off for a few seconds it will try to boot itself again, but then fail a few seconds later and just continue the cycle. I have to actually push the power switch in the back and leave it off for about 15 seconds to get it to stop. My first suspicion was that my power supply is dying, as the first one I had died within a couple months of building my PC and I sent it in for a new one.
I actually had this same problem a couple weeks ago, but managed to do a system restore and it actually seemed to resolve it, until now. Basically, does this sound like a dying PSU? I'm tempted to reformat Windows to see if that does anything but it would be a real pain in the *** to lose the contents of my hard drive only to discover it actually was a hardware issue rather than just some nasty virus. Anyone have any ideas?
In case it matters, my specs are:
Intel i-5 2400K
ATI Radeon HD 6850
8GB Corsair RAM
Corsair CX600 PSU
