You say that you are not overclocking CPU or GPU, however you state your Ram is running @ 3600MHz.
To stay within spec bring that down to 3200MHz.
Also CBP and PBO are basically overclocking mechanisms. For now make sure both are disabled.
Run with this. Performance will take a hit. However one must walk before one can run.
If you have HWINFO64, post a snap. Also snaps of CPU-z (CPU, Memory, and SPD tabs)
Take a look at event viewer... are you showing any WHEA errors? if so post the most common
