try borrowing a PSU from a friend and using that for a while, could also be overheating CPU(please tell me you put thermal compound in between the cpu & cooler)

a friend of mine had a similar issue, turned out to be his PSU, we found out after about 2 weeks, in which time his HDD died and motherboard aswell :/.(he did receive replacements tho)

anyways, i can recommend getting a program called HWinfo64, it should show you pretty much all voltages, temperatures, etc.

you can get this software here(portable is best, as you ca remove the folder when ur done):

i5-6600K[delid]@4.824GHz Core/4.623GHz cache@1.456v | 2x4GB Crucial-DDR4-2400MHzCL17@3015MHzCL12@1.45v | Sapphire Nitro+ SE RX 590 8GB@1645Mhz core@1.15v/2236MHz@1500MHz timings BiosModded

✔ Best Answer
Get temps and voltages and post results. I use HWMonitor.
Even new it cannot hurt to clean the contacts on the memory with a soft clean pencil eraser, remove dust, and put them into the sockets and remove them 4-5 times to burnish the contacts as well.
Make sure that the motherboard posts all have a screw in them and are tight (and no posts where there is no hole in the motherboard. Some of the screws on the motherboard also ground the chassis so good and snug is better (just don't force them too tight as to break the motherboard).

You have to be a little bit crazy to keep you from going insane.

Can you get in to BIOS and check voltages and temps.
Stay monitoring for a while and see if temps rise quickly or voltages become unstable (CPU voltage may fluctuate depending on CPU power settings)

Disable the auto-restart feature, that will allow an error message to be displayed.
