[SOLVED] Can boot into Windows but not into BIOS

[ChickenFromOuterSpace]

I noticed a strange issue with my custom-built PC that only really recently paid attention to since I need to turn on virtualization for Bluestacks. I'm able to get into Windows 11 just fine, but I'm not actually able to see the BIOS.

This isn't only limited to BIOS. I can't see POST or advanced startup either. I'm using a Ryzen 5 3600 CPU, GPU is a Geforce GTX 970, and my motherboard is a MSI b550a. I'm not sure what to make of this issue.

Pasted the report CPU-Z gave me here: CPUZ - Pastebin.com

It is just your fast boot is set to on, which goes too quick to be displayed... You could follow this guide to get into UEFI settings you need.

Ok, I turned my fast boot off from the Power Options > Choose what the power buttons do setting but something even weirder happens. When I try going into BIOS by spamming the DEL button, I get stuck on a black screen instead of loading into Windows.

I also got stuck on a black screen when I tried that guide. As in as soon as I picked the advanced startup option, the video feed turned off from the restart and then never turned back on again.

Hard restarting did bring me back to Windows every time at least.

It looks like your GPU is too old for this motherboard, check page 43 of the manual.

That makes sense, GTX 970 could have issues with GOP since it was released about 8 years ago. I'll try to get my hands on a newer GPU and then give an update after I get it in there.

Finally managed to get it working. I was looking around for similar issues and troubleshooting steps and found the connecting to a TV option. Somehow that got me into BIOS even though connecting to multiple different monitors didn't.

So, I switched my BIOS to from UEFI to CSM and now my Geforce GTX 970 can see POST and get into BIOS now. I'll still mark the answer as best since the fact I need to switch to CSM at all means it's too old.
