OS - Win 8.1 64bit

As you can probably tell by the components I built this computer ~ 2 years ago. Initially the board had problems with a bad batch of silicon so I got a replacement a few months later (rev 3.0) I believe. Everything has worked fine, I ran some overclocks and ran the CPU at 4.8 ghz for months until I got a blue screen, I backed it down to 4.5 ghz 103 clock x 44 multiplier for the remainder of the time. No blue screens no problems.
FAST FORWARD (No idea if this is relevant but seems like it could be) moved to a new apt, shitty wiring in the unit has my rig tripping a circuit 7-8 times before I run an extension cord from the other room.
PROBLEM - A few days in and I'm figuring I have it all fixed when the computer turns off again. No blue screen, just instantly power off, no lock up, no residual image or sound, just off. Won't power back on, so I figure my PSU is dead or I have a thermal problem. I give it some time to cool off, and unplugg.replug the psu and reboot and run CPUID - monitoring thermals, CPU is peaking at 60c and graphics at 85C - to be safe I take the side cover off and blow a fan on high into the case, I also reduce the cpu overlock to 40 mult. x 100 clock. Temps drop to 53C for the CPU and mid-high 70's for the GPU. IT happens again. black screen won't power on, so now I figure it's the PSU. I don't have testing tools at home so I bring the rig into Fry's. They run a test and the PSU is fine, all the voltage measurements are within their range. I bring the whole computer in and initially it looks like maybe the A1 DIMM slot is bad, but we re-seat the RAM and everything seems to be fine. I take it home and it works, flawlessly for 2 weeks. Last night it starts happening again. I try running with only one stick of RAM but it still turns off.
I've come to the conclusion that it's the mobo, but I was hoping someone here might have some insight before I RMA?
Also - I've updated the mobo Bios to the newest download on the ASUS website.
I'll be running memtest86 tonight to make sure it's not the RAM.
any help is appreciated! thanks.
