I've had this problem for probably 2 years now (got the prebuilt PC in late 2017) and can't seem to solve it. I can go for sometimes a few weeks of leaving my PC on sleep or shutting it down and it works fine. Then, without any pattern it will not turn on. The refusing to turn on can last from an hour to days. Usually, I will just leave it on 24/7 because once it is on it functions completely normal. Here are some things I have tried:

  • Replacing the PSU: I tried this a while ago while the computer was refusing to turn on, and after installing a new PSU it still refused to turn on so I just put the old PSU back in.
  • Replacing the GPU: I think I tried this because I was getting random shutdowns/restarts.
  • Replacing CMOS battery
  • Updating BIOS (seemed to help with random shutdowns/restarts
  • Reinstalling windows
  • Checked mobo for capacitor issues
I have seen other similar forums on here and other website, but none of them have helped. I took the PC to a repair shop and they couldn't find any issues, probably because the issue isn't reproducible. If anyone has suggestions I'd love to hear them.

Some setup info:
ASRock Ab350 Pro4
Cooler Master MWE 450 Bronze
Ryzen 1300x
EVGA 1050ti

try turning fast startup off - https://www.tenforums.com/tutorials/4189-turn-off-fast-startup-windows-10-a.html

update chipset drivers - https://www.google.com/search?channel=crow5&client=firefox-b-d&q=AB350+chipset

sleep problems can be drivers

Can you download and run Driverview - http://www.nirsoft.net/utils/driverview.html

All it does is looks at drivers installed; it won't install any (this is intentional as 3rd party driver updaters often get it wrong)

When you run it, go into view tab and set it to hide all Microsoft drivers, will make list shorter.

Now its up to you, you can look through the drivers and try to find old drivers,

  1. or you can take a screenshot from (and including)Driver name to (and including)Creation date.
  2. upload it to an image sharing website and show link here
All I would do is look at driver versions (or dates if you lucky to have any) to see what might have newer versions.
