A few months ago my computer began freezing and crashing. I don't get a bluescreen, just suddenly turns off when it crashes. Sometimes it turns off when it freezes, and other times I have to reset it. It usually freezes during videos or videogames, especially cut scenes... though videos from certain sites like Youtube work fine. And I can play certain video games as well and they don't bother it.
I've already tried replacing the power supply and applying new thermal paste to the CPU, but this hasn't helped. I tried switching a different Hard disk with Windows on it but I got a blue screen when it tried to start up... though that hard disk has been sitting around for a long time; I can't verify that it would work anyway.
As you can see below, TMPIN2 on the motherboard heats up when I run the diagnostic or play a video game. From what I've found, TMPIN2 is CPU. I'd suspected the graphics card but this seems to indicate that its the CPU. I want to get more opinions before I go and buy another CPU. Here is data from CPUID Hardware Monitor.
Edit: I've tried updating graphics card driver and I've scanned thoroughly for viruses as well. The replacing the hard drive was my final attempt to make sure it wasn't a software issue.
Edit2: Even if I using an overclocking tool to turn down my CPU, it doesn't help... this makes me question whether it is the CPU.
