i'm experiencing some ocasional random freezes in my system and i'm struggling to find the reason.
the problem: PC completelly frozes the screen and i have to reset.
when:in the last 7 days, it happened 4 times. first time just after loading into a map in csgo, 2nd when i was casually browsing the internet, the 3rd after more than 2 hours playing project cars and the last one just after booting the pc, opening the task manager and a random folder
PC Build: it is overclocked but it is stable (pass in prime95 and IBT AVX) and stable at gaming (deus ex mankind divided, forza horizon 3, Doom, csgo, etc)
cpu: amd fx8370e overclocked to 4.3 (210bclk x 20.5 multi) max temp reached 62º, voltage set at 1.306~ in bios, llc medium, max vcore 1.332, min 1.306.
RAM: corsair vengeance 2x8gb 1600 ddr3 (XMP, running at 1679 because of bclk 210)
mobo: gigabyte 970a ud3p v2 (max temps registered 65 and 60. cpu socket and nb i believe)
psu: coolermaster gx650
gpu: galax 970x 4gb oc edition, overclocked (max boost 1420MHz core, 3600MHz memory) (max temp reached 82)

WHAT I THINK IS CAUSING IT: HDD (sorry, i don't even remember the model, its an old-old 1,5tb drive.
why: windows memtest did not accused errors. it is running with 210 bclk but with higher timming in the XMP and nb vcore is adjusted with a 0.05+ offset
gpu overclock is ok (one time it reached 112% power usage and stayed pretty fine.
cpu overclock, as i said is ok.

-Everytime that it crashes, the drive led stays on until i reset the system.
-the only time that i've got a Bsod was when i started the disk defrag win10 tool. in the middle of the process it bsod.
-the only event in the event viewer when the freeze happens is the kernelpower 41, with little variations in the numbers.
-there's a considerably time after the last fresh format.

what i've already did:
-chkdsk /r
-sfc /scannow
-verified the drivers
-updated windows
-the energy supply in my house is a little crappy, but if the pc can handle at full load and stress testing, i doubt that it would do that even at idle...
-the overclocking with BCLK give more a bit more performance and i was suspecting that, but, like the energy thing, there's no reason to freeze at idle and survive gaming and stressing... bus speed stays constant (tiny variation -209, +211) and the cpu clocks dropped max to 4.200 registered at HWMonitor and didn't even registered drops with hwinfo64

what do you guys think that it could be?

PS: i just finished the chkdsk today. since i didn't got any crashes, but they are so sporadic that is hard to tell..
