CSM support randomly keeps getting reenabled

[SpaceOperator]

I'm on AM4 and I have a gigabyte x570 elite wifi board bios version F11, running windows 11 home. just recently its started to say no boot device found and I went in to the bios and CSM support was enabled and I disabled it and re-enabled Trusted platform module ftpm 2.0 and it loads back into windows. I had a hangup once recently that reset the bios to default, and windows boot loader couldn't detect and any of the drives that showed up in the bios, but after a few restarts it finally fixed itself. Now I just have CSM turning on again any suggestions on how to keep this from re-enabling itself?

 

I have a new ssd coming to replace my boot drive currently is a 128 gb and I ordered a  1 Tb ssd because I only have 20gb free and I hope that a fresh windows install will fix any boot loader problems. I'm going to replace the cmos battery too to see if that helps.

Like you mentioned, it is a good idea to replace the CMOS. Update the BIOS to newest version whilst you're at it, too. If you already are on the latest version, a reinstall won't hurt.

Swap the CMOS battery. Its a ordinary type CR2032 battery.

Hopefully replacing the cmos battery will fix it, it doesn't do it every time I boot but occasionally it will just reset, I'm going to get a battery when i get off of work today and hopefully that will solve my problem 

 

Question Should I update my bios version I have heard conflicting reports on this some say to do it other say not to unless its for new hardware because it could brick your system? never done this before running bios version F11 from 2019 or 2020 there are several updated bios version from the one I'm on

Even if you have a problem with a new BIOS, you can always flash a previous BIOS. Your motherboard even supports the flash of BIOS without CPU nor RAM.

Updating a BIOS is nowadays way safer than it was.
