3.3v rail is undervolting to 2.8v.
VDDA2.5v is overvolting to 2.8 on occasion.

New build, been using it for over 3 weeks withoit problems. In those 3 weeks my cpu was oc'd to 3.9ghz and was working fine.

Pc randomly shuts down, after which it tries to reboot and fails but keeps on doing.

I tried doing a cmos reset. It was successful but did not help. I also noticed a quite but worrying crackling sound coming from the cpu.

Any ideas? Thanks in advance.

Are these readings from Bios?

Your PSU isn't the best quality - CX600 - http://www.corsair.com/zh-tw/cx-series-cx600m-modular-atx-power-supply-600-watt-80-plus-bronze-certified-modular-psu

You shouldn't OC the CPU unless you have a good non-stock CPU cooler eg CM Hyper 212 evo. Could be the CPU is getting too hot and shutting down.

Use your Mobo - http://www.asus.com/au/Motherboards/M5A97_EVO_R20/ - "UEFI BIOS

I turned off the oc after I experienced the first crash. But it still kept happening. I also tried a cmos reset with the jumper. It was successful but it did not stop the over/undervolting and crashing.
