CPU temp rising very fast

My computer has basically been running flawlessly since I built it earlier this spring. While surfing the net last night, my computer suddenly shuts off. I pressed the power button and when it gets to the windows loading screen, it shuts off again. I pressed the power button yet again and it shuts off before the windows loading screen pops up. By now I knew that something wasn't right, so I went into the BIOS and noticed that my cpu was at least 80 C and rising by the second.

I turned it off for a several minutes to let it cool off and I went back to the BIOS and it was at 50 C and rising by the second again. I exited BIOS and this time I was able to get to my desktop; I opened up speedfan and core temp and my cpu was definitely running hot. Core temp was getting a reading of about 70-80 C and speedfan was somewhere around 50-60 C. I got chickened so I shut it down for the night, hoping that all it needed is a good cleaning.

Today, I took it outside to clean (I didn't want all the disgusting dust flying all in my room) where it was barely 10 F (I live in the midwest). After cleaning, I powered up my pc again and went to the BIOS and right away, my CPU was at 30+ C and rising extremely fast. I couldn't even get to the desktop before it shuts off. Right now, I'm thinking that it's either my CPU, or PSU or maybe even a virus. My CPU is a intel e6750 with a stock heatsink & fan. My power supply is a HEC-650DR 650 watts. When I turn on my pc, all the lights, fans, etc comes on.

Obviously I'm sure the problem is due to my cpu getting so hot. I'm usually idling close to 30 C and after a gaming session, my cpu quickly drops back to idle temps.

So, I need some help figuring out why my cpu is getting so hot so quickly or what's causing it to do that? Is it that my cpu just got fried? Any help would be appreciated. Thanks.

Make sure the Heatsink is secured properly and re-apply thermal grease.
The "pushpin" stock intel heatsinks are notorious for coming undone.

sounds like the heatsink has come loose, take it off, clean the old paste and apply some new, plug it back. make sure the pushpins are all the way through and 'locked'.
