Are these correct Voltage readings?

I got these results from CPUID HWMonitor
I have a feeling that my PSU is failing, which is what I need to confirm.

Possibly. Could be a bad hdd, could be malware or a virus attacking your data and/or registry, could be software you recently installed or updated creating issues, could even be driver errors being saved at shutdown creating issues. There's no definitive way to tell for sure, you'll just have to go through your pc bit by bit and start eliminating potential areas. Malware and virus is easy to work, as is restoring system files, there's also programs to check the health of your hdd, WD Tools or Seagate etc.

I've even seen where it was a bad switch not providing good enough contact to allow the psu to turn on, seen where a short in the usb cable from a keyboard was tripping psu protections and preventing it from turning on, requiring a...
Can't trust software in the slightest. According to Hwmonitor, Asus mobo software, SpeedFan my 12v rail reads as 8.12v. There's no way the pc would even work at that voltage The cpu voltages you list are what the cpu is using, not what the psu is outputting.

As rexper says, only a physical test with a multimeter is an accurate way of measuring. As far as a failing psu goes, there's other ways to determine that, but generally psus do not die a slow death, being made up of capacitors, if a cap fails, the psu is toast. Internal power/voltage/current protections will prevent the unit from turning on. (unless you have a real piece of junk with junk protections, in which case you are doing damage to other components)
 
Well my PC won't turn on sometimes. The GPU fan, Cooling fans, LEDs all turn on for a second or two and then the PC shuts off keeping only the Motherboard LED on.
This happens about 50% of the time that I try to switch on. Once it switches on properly, everything is fine except for a 0xc00000e error which happens very few times (while working, playing a game, even watching a video).
At first I was using a UPS, thought maybe the power supplied was not enough, so plugged into the wall, but still the same thing happens.

My PC
MB : Aorus Ultra Gaming X470
Processor : Ryzen 2600x
RAM : Vengeance 8GB DDR4 3000
3 HDDs 7400 rpm
GPU : AMD R9 270x
PSU : Corsair VS550
2 Cooler Mastee Fans
UPS : APC BX600C-IN 600VA (although I'm not using this now)
 
That error is a boot error where bios is trying to activate a corrupted registry. Usually due to some software change. If/when you get pc running good, I'd do a full malwarebytes, hitman pro and spybot: search and destroy runs, as well as any Antivirus you have. I'd also do a CMD as admin, /sfc scannow to fix any possible corrupted system files. From the looks of things, I'd be more worried about a hard drive failure than power failure.

Your sometimes boot, with sometimes errors is about as bad as it gets for diagnosis, since there's half a hundred different possibilities, so only trial and error and patience and 'out of the box' thinking is sometimes required. You'll need to find the root cause, most will simply wipe out everything and do a full, complete reinstall of windows, but a bad cable or bad hdd or bad psu won't be fixed by that.

So crazy thing, tried everything, changing PSU, GPU, HDDs, RAM, all of it, still was just not happening, then I remembered how you said might be a bad switch, yup, A Bad Switch on the Cabinet!!
 
Yeah, it's crazy how sometimes it's the smallest thing that's the issue. Switches seem to last forever, one of those small things everyone takes for granted. I saw it personally when the switch on my old Dell 8400 tower went bad, drove me nuts. I spent hours on the phone with Dell over the same issues and more that you saw.

Now the road to recovery lol, kudos on finding that. Cheers!
 
Can someone please provide a link to a document that shows what each voltage does?
I just changed out my 400W PSU for a 750 -- I had thought that my PSU was failing since Open Hardware Monitor showed rather large variation in Voltage #7.

The variation still exists in Voltage #7
Here are the values from the past 24 hours:
Min 0.792
Max 1.088
Avg 0.857

I would like to know:

  • ■what this voltage is -- ie, what systems use this voltage
    ■what is the expected value
    ■what is the acceptable range

I'm a bit worried that I may have a motherboard with a failed/failing voltage regulator.

Thanks,
 
VIN stands for "Voltage Input" and it's a generic naming for sensors which meaning is unknown. Such sensors are most probably not used (not connected to a real source) on mainboard and thus can provide erratic values. I wouldn't worry about it.
