Hey guys!
I have trouble with my PC and it freezes every few hours with a screeching sound:

don't have sound too loud as that screeching sound is really annoying!

Servis guy said something about GPU and formatted the system, so needed to buy new GPU raden RX 570 , but the problem is still there.
PSU is Corsair CX750

Motherboard Asus Z170

I have run memtest and there is not errors with RAM, I ran diagnostic for one SSD disk 860 PRO, but not for one other m.2 SSD and I have a WD HDD inside as well.

I have run some Intel CPU diagnostic and no problems there. Is this usually some power problems? That is why I had recording on voltages and temperatures of CPU running on my phone, so can I safely dismiss the PSU as the problem?

I am considering just buying a new motherboard as that seems most likely.

Does anyone have any clue or experience with that?

Thank you so much!

I was mostly looking at the rails +5, +3,3, +12, I thought that would indicate that PSU is not working good. Along with temperatures. But everything seemed fine. It is hard to recreate the crash, it just happens after few hours. Was trying stress tests, but it did it without problems (well didnt do it for long time, just tried to maybe see where the fault lies if I could make it crash)

I wasnt recording othervalues as needed to use the phone, but nothing seemed to really go out of the norm I think, temperatures also ok.

Can it still be PSU even if voltages seem fine?
