Windows 10 stalls at boot, power plug pull fixes it.

I think I have a PS problem but I'm not certain. Recently I've had problems with Windows 10 stalling upon startup at the Asus "enter BIOS" key screen. I then switch the PS off at the PS, pull the plug, wait about 30 secs and then reconnect PS and then press the computer start button and so far, it boots right up as normal. I've done some searching around and seen several postings that say that's an indication of a failing PS. I've purchased a replacement that's due to arrive on Wednesday but before swapping the power supplies out I thought I'd ask the community here about the problem to see what they say.

The equipment involved is,
Corsair RM750 that is close to 5 yrs old.
MB is ASUS Z170-A
The boot drive is Samsung SSD 850 EVO 250GB
Graphics card is Nvidia GTX 960
There are also 2 HDDs, both of them being WD 3TBs
Windows 10 Pro(x64) v2004 (build 19041.685)
It's been running on the Asus fan control mode of "Silent".

The machine is not used for gaming, mostly just web browsing and general multi-media such as audio/video playback.

While the current PS is about 5 yrs old, and everything fails eventually, it just seems a bit premature to me.

Looking for some input, thanks!

The problem is not Win 10 related.It is either or both motherboard/psu,if your description is correct.
Win 10 only becomes involved after the bios has completed it's POST.
If you are able to,disconnect all power and peripherals i.e. camera,printer etc.
Then remove the small circular battery from the motherboard,noting the positive/negative orientation.
Press the power switch for about 20 seconds,which,theoretically,should drain the capacitors.
Wait for around two minutes then reconnect the circular battery,correctly orientated.
Restart the computer,ONLY with the operating system drive connected and see if that works.Forgot to mention,keyboard and mouse can remain connected.
If it does,then shutdown and only connect one piece of hardware at a time,to see if it is the cause.

Will removing and then re-inserting the battery reset the MB's BIOS? In other words, will I have issues with the additional drives and possibly Windows itself when re-inserting?

And yes, I don't believe it has anything to do with Win10 either, I added that just in case. When this happens I never hear the single beep upon POST, when it does work I hear the beep and the computer starts up correctly.

I'll disconnect the peripherals and the non-OS drives tomorrow, it's about midnight right now where I'm at.

Thanks

Yes,it will reset the bios to the default setting.
If the bios operation is normal,then all peripherals should be recognized when re-attached.
If the bios is faulty,,then it can be "flashed".You must visit the maker's site to find their preferred method,because it can have risks.
With respect to bios beeps,check your motherboard does have them and their meaning.
Good luck.
