They are both basically stress tests. Run MEMTEST first. Disconnect any non essentials from the computer. Don't let it run for just 15 minutes, make sure it is ran for AT LEAST 1hr, preferably longer. This will tell whether or not it's the memory causing problems. Run OCCT to test multiple things, such as GPU and CPU reliability and stability.
Ok, I downloaded both Memtest and OCCT, both of which detected no errors. I ran the Memtest for over an hour and ran all the tests in OCCT for an hour each. So I guess that counts out the RAM, CPU, Power supply, and graphics being the cause of the issue? Funny thing is, my computer didn't shut down once during the diagnostics. It's been running smoothly all night. Very frustrating! I'm now inclined to think the Motherboard is the issue.
