Well last night I got all my newegg parts (first time builder) built it up and installed Starcraft II. Was playing SC II ifor a few hours while surfing the web and other stuff at the same time with no problems at all. So the next morning I put on the side panels of the computer and start it up, and after 10 mins the comp just shuts off randomly. I tried starting it up again then it turned off after 5 mins, and I tried again and each time it stayed on for a shorter amount of time, so I concluded it was a temperature problem.

So anyways, I downloaded Speedfan and having no other programs up it says my main core was around 90C and I waited until the comp shut off and when it did it was around 110C..

The thing I don't understand is how I was able to play Starcraft II while multitasking the night before then all of a sudden it's bugging out.

Thanks in advance
