So I just built a new computer (my first) about 4 months ago. It ran really well for the first 2 weeks or so, and then started shutting off. No warning or anything. Thinking that maybe the CPU was overheating or something, I looked around and read that the heat sink could be dusty and that could effect it and cause it to overheat. So I tried cleaning it, which seemed to work just fine.

Now it's starting to overheat again, and I have no idea why. I tried removing the fan and cleaning it again, and it didn't work. It doesn't matter what I'm doing on the computer, I could be gaming and it'll be fine one day, and then the next it'll turn off. Today it won't stay on for more than 5 minutes just on the login screen. I have no idea what to do and I'm getting a bit frustrated. I pulled up CPUID and everything seems to be ok with the power supply and the temperatures.

Any ideas on why it could be turning off like that?

If it helps, this is my build:
AMD FX-8359 processor
ASUS M5A97 LE R2.0 Motherboard
Corsair AX860 power supply
ZOTAC AMP! ZT-70402-10P GeForce GTX 760 Video Card
and a Corsair hydro series H60 water cooler for the processor

When it shuts off it stays off, but I can turn it back on after about a minute, but it doesn't always stay on. According to CUPID the highest the CPU gets to is 76 degrees celsius before it shuts off. The idling temperature of the CPU is around 33 degrees. 3.3V is at 3.118 5V is at 4.996 12V is at 11.952
Could it maybe be an overheating issue?
