So this doesn't happen all the time, but every now and then my PC will suddenly lose power. It doesn't go through the shut down process, it just dies. Then after about 5 seconds it starts to restart. It either restarts successfully and loads back into windows, or it does this thing where it starts up for one second, then powers off, waits a second, then starts up and powers off again. It never powers on after that.

I've found out that opening up the case, pulling out the power cable connected to the motherboard and plugging it back in fixes it. Once I do that it starts up next time I try to turn it on.

Here are my specs:

Corsair 16G (4x4GB) Vengeance CMZ16GX3M4A1600C9 DDR3
Intel Core i7 2600K Processor LGA1155 3.4GHz CPU
Asus P8Z68-V PRO Socket 1155 Intel Z68 Chipset
Crucial RealSSD C400 128G SATA3 M4 Series
Western Digital Blue 500G SATA3 HDD Caviar Blue
Antec 620W High Current Gamer Modular PSU
Fractal Design Define R3 Case Arctic White edition
Noctua NH-C12P SE14 CPU Cooler
MSI 980 gtx 4gb gaming

Hey, guys. I ended up replacing the motherboard and CPU a month or so ago. Got an ASUS Sabertooth and an i7 4790k. Been running smooth ever since, so I'm pretty sure it was my old motherboard that caused the problem.

Yeah, I'm super happy with it so far. Haven't had a single issue. Doesn't seem to be anything quirky about it. Boots the PC up way faster too. like 5 or so seconds.
