Question 1.866.581V GPU spike?

[RetroRebel]

In the image you can see how the hardware monitor registered a voltage spike of almost 2 million volts.
This sounds crazy, I'd find it really hard to believe. Even with my limited knowledge on the matter I'd think that that much voltage would blow my PC to pieces.. Stil.. I've been having BSOD because of hardware malfunction for a good while now. And been testing and trying everything I could to get it fix, even sent the PC to service, but still happens.
For instance last night I was playing a game that's not that heavy (PoE: Deadfire) and my PC restarted on its own. When I went to check on the errors log to see what happened, it showed it as a hardware malfunction (Code 124)
I'm going nuts trying to figure out what's wrong, thought it'd be a temperature problem, but apparently the temperature is fine. Also tried changing to a newer HDD, but still happens. Installed Win 10, but no change.. and I could go on with the things I've tried.

Please, help me.. Could this be the reason why I'm getting all these shut downs because of a hardware malfunction?

I suspect a defective sensor. That level of voltage is simply not possible.

Have you tried measuring with an alternate application, like the Radeon software installed with the current drivers?

Nope I haven't, yet. Thanks for the tip I'll give it a try.
Could I bother you with giving me any recommendation that'd come to your mind with finding out what's causing these hardware malfunctions? Any way to stress test each hardware to see which one failing?

Edit: By the way I'm checking the Radeon software to see where can I check my gpu's voltage, but can't find it anywhere.
