Question PC randomly crashes without any alerts ?

For the past 7 month my pc keep crashing randomly without giving a notice first (there is no BSOD) I checked the event log showing kernel-power 41 (63). Earlier this month I try to set the offset voltage to -0.05V this seems work but only for a while the random crash rarely happen. But when it happens sometimes the BIOS setting reset to default. Does anyone know what happen to this PC is it the MOBO fault, PSU, or something?

Also I already install new window on new storage and this problem still happening

PC Spec:
CPU: Ryzen 1700
VGA: GTX1050Ti
MOBO: Asrock x370 Taichi
PSU: ANTEC Neo Eco II 650W 80+ Bronze
RAM: Team Elite Red plus 16GB

If there are no suspicious temperatures, PSU would be the next likely culprit here. While it's kind of a cheap PSU -- though better than the horror tier -- it's not the worst match in the world for a 1050 Ti build, but even high-quality PSUs can fail sometimes.

The kernel power 41 error just indicates the system shut off or rebooted unexpectedly rather than pointing to a specific problem. But you're definitely aware that your system is doing that!

I already monitor the PSU voltage through HWmonitor seems there is no dipping happening here. Also I already hire someone to troubleshoot this case and the funny thing is the pc did not crash at all when they run multiple test to the pc.

Is it possible if the CMOS battery from the motherboard cause all of this? Looking that the BIOS reset itself that could giving false temp failure, voltage drop, or failed to communicate with the driver?

You cannot diagnose a PSU problem with HW Monitor other than the basic, broadest voltage. Otherwise, you'd have as much luck doing a red blood cell count with a flashlight.

Ahh I see than, so it's not the CMOS battery like I mention before right? Any suggestion how to check the PSU if it is working normally?

It's unlikely to be a battery issue.

Unfortunately, the proper way to see if a PSU is working normally involves a load tester and an oscilloscope, which would cost you the price of multiple new PCs. And even then, it's kind of a pain; I have access to these and have tested my own PSUs before, but generally, if I have a reason to even suspect one of my PSUs is becoming an issue, I just swap it out. It's safety equipment, after all.

In the end, swapping out to a known working PSU or a new one is the best practical test.

Ah I see buying new PSU also will cost me a lot HAHAHAH. Do you know why my BIOS setting reset to default?

There *could* be an unrelated CMOS issue, but it's extremely unlikely to be the *cause* of your main problems.

If you're hiring people to monitor your PC, a PSU replacement would be less expensive. Unless, that is, you're paying the technician next to nothing, in which case that's about what their advice is worth (unless they're a friend donating their time).

Alright so most likely this error kernel-power 41 (63) happen because temperature and PSU.
