I'm having the same issue.
I just bought my computer less than a month ago and it's crashed 8 times.
Once during the first week, once during the 2nd - then saturday it crashed 3 times and today, 4.
I reapplied thermal paste (the company I bought it from said to do so) I also DL'd speccy and CPUZ
Right now... speccy lists this: fyi I have a game running in the background, chrome, skype and that's about it.

Your reply about this
"If by chance the OCCT software shows the vcore (VID) voltage dropping to .875v and the CPU frequency dropping to 1400 MHz. at the same time when the PC is under load, then there is a high probability that the mobo VRM circuit is overheating and throttling the CPU to allow the VRM circuit to cool. The only solution is more fan cooling of the VRM heatsink or a better mobo."
Interested me... I'm about to send this thing back for repairs and I'm wondering if I should bring this up.
Whenever I'm running a game - my CPU temp in speccy spikes to 75 C.
I use - Asetek 550LC Liquid CPU Cooling System
