Oddity in custom built pc

My pc has been acting strange lately.

Oddities:

1. When I start the computer, the screen backlight turns on, but it takes 1-2 min for the mobo screen to show up.

2. When I go to File->Shut down pc, nothing happens.

3. When I go ctrl alt delete, shut down pc, it takes a long time for the pc to actually shut down.

This happened suddenly after I unplugged my keyboard doing a normal boot up .. I have no idea if this cause the issue, but I noticed these oddities started happening after that point.

Any idea what’s going on?

I run windows 11
