In the event of a shutdown, check the logs after a reboot and see if it correlates with a increase in CPU or GPU temp.

Hmm GPU is possible, I do have alot of graphics cards issues. Things like suddenly crashing drivers.

Have a link to that program?

Sure.

It's freely available from a number of download sites, if you prefer download.com or something else instead.

Says the GPU got up to 45c before it crashed. Whats considered acceptable range?

That's not even close, damage doesn't usually begin until you're well into the upper 80s or 90s Celsius. I think we can rule out the GPU overheating. It's unlikely that it's the CPU overheating too as it doesn't happen consistently during times of high load. This is sounding more and more like a power supply issue.

From Tom's Hardware:

Download and run OCCT ( http://www.ocbase.com/ ) select the power supply test on your system, this will push your HDD, ram, CPU and GPU at the same time (stressing the power supply.)

There are frequency, memory, and temperature monitors to show you whats happening with your system. Run the test for 30 minutes and watch your system the whole time. If your video starts giving you artifacts/garbage, then its probably running too hot or been damaged, if you get a BSOD, then your CPU/motherboard may be damaged. If your system locks up or restarts then its probably your power supply.

Before hopping on the thermal bandwagon eliminate other avenues. Test your power supply first if you have a PSU tester. If you don't then take it to a shop that can. Pretty much any place will do this for free.

Check for any shorts or bulging capacitors on the mobo.

Replace the thermal compound on the CPU. If you know how and are capable of doing so, do the same for the GPU. Generally good to do so every once in a while anyway so it can't hurt.

Make sure all connections and components are firmly seated.

Try not to run the computer unless absolutely necessary, continuous hard shutoffs will only exacerbate the problem and potentially harm other components.

I'm betting on the PSU, as randomly timed shutoffs are generally indicative of this component failing. But, again, test before jumping to conclusions.

what if nothing happens? I ran that thing for a little over half an hour and while my framerate went to single digits at times and a few sensors were running hot it didn't crash or lock up

some more information. THis is an issue I used to get, but haven't since I wiped my boot drive. However it started up again after I got java and started playing modded minecraft again
