I've made 2 threads regarding the issues I've been having, and I think I've figured it out, but want conformation from someone who knows better than me.

I've been having issues with my PC crashing during games, which I originally thought was my GPU. Through various stress tests, the GPU ran fine, but crashes during games. Then I went on to the RAM. I ran MemTest86 for a solid 3 hours, 0 errors. I then ran Prime95 for the 3rd time. (The other 2 were earlier that day, but I don't have results for those 2, but remember some.) The first time I ran it, I let it run last night, and woke up to the program has stopped working. I then ran it again a few hours ago, and worker 2, 5, and 7 stopped working 20 minutes in. I then ran it again 10 minutes ago. I ran the test as a custom blend, using 14.5GB of my 16GB of RAM. Here's the results.

As you can see, worker 5 and 7 stopped working, which seem to correlate to cores 4 and 6. The CPU was originally pinned at 100% use, and once the 2 workers stopped, it dropped to a constant 75%. The Ram usage also went down from the 15GB range down to 11.6GB. Clearly something isn't right here. My CPU is an FX-8350 running at stock speeds, so anything relating to a possibly unstable overclock is out of the question.

I'm drawing the conclusion out of this that the CPU is taking its dying breath, but I'd like some form of conformation from someone who's more experienced with this before I start digging a grave for my chip.

The EVO is tall enough that the air doesn't move over the VRMs. Like I said, test the theory with the side panel off and a desk fan.

I would look at the voltage regulators on your motherboard overheating. What motherboard and what CPU cooler?

To test this theory, you could take the side panel off the PC and point a desk fan at the CPU cooler. It will also cool the voltage regulators around the CPU.

That could be possible. I have a Gigabyte 970A-DS3P Mobo which is a cheap piece of junk with a Hyper 212 EVO. If the VRM's were overheating, how would I go about fixing it?
