[SOLVED] Odd intermittent boot issue

[gollum6519]

Hi everyone. I have a question about my computer's behavior and this seemed like a good place to ask. I've been building my own PCs for over 20 years, so I'm fairly well versed in how it's done, though this particular PC was not built by me. It is custom-built, but someone else built it.

Anyway, here's my issue. I've had this PC about 2 years now. Sometimes, from a cold boot, the PC will do the following....
Black screen....
POST splash screen...
Black screen....
(Monitor gives a "no signal" error)....
Black screen....
POST splash screen...
Boot into Windows 10 Pro

After the boot into Windows the PC works perfectly and never gives me any issues. But this happens about every 2nd or 3rd boot up from a powered off state. It does not happen if I tell W10 to restart.

Here are my specs:

AMD Ryzen 5 2600 (not overclocked)
MSI B350M Bazooka
32 GB DDR4
Zotac 2060 Super
C drive is a Silicon Power 500 GB SSD
D drive is a Samsung 970 Evo m.2 500 GB SSD
E drive is a Toshiba 500GB HDD

I should mention that on very rare occasions....maybe 3 or 4 times in 2 years, the PC wouldn't POST. I ended up having to leave it off for a while and come back, and then it booted. If I remember correctly I chalked this up to heat. I am an avid Flight Sim enthusiast, and our simulators tend to be very tough on hardware.

This doesn't seem to be a huge deal because once it boots it seems to work fine. But it is slightly annoying so I thought I'd ask here if anyone had any ideas on what would cause this?

Thanks in advance.

Since it doesn't ever happen on restart, try disabling fast boot in the bios.

Thanks for the reply and that's a good thought. I just went through the bios and couldn't find that option. I remember it from older bios versions but unless I'm missing it they seem to have taken it out. It's the November 2019 bios from MSI.

Unfortunately MSI does not update the bios section of the online manual for anyone without your exact board to help.

Yeah, thanks. Not really a big deal I don't think. Just an annoyance. Curiously, the notes for that latest bios update says "Improved boot performance". Ummmmm....ok

Well I thnk I may have stumbled onto the issue. I was looking in the Windows Event Viewer and noticed some "Windows Fast Boot Failure" errors. So I turned off windows fast boot and it hasn't happened since!
