Details? Version of the bios? CSM required if Windows isn't set up correctly. Windows must support Secure Boot and lack any compatibility support module.

My motherboard is an Asus Prime B-360 m-A, running BIOS version 3202. It seems unlikely the Windows setup was the cause since it worked before. The problem began after switching GPUs and changing DDU settings from nvdia to AMD. I plan to reinstall Windows to check if that resolves the issue. Thanks!

I can't directly check the voltage of the CMOS CR2032 battery for you. You'll need to use a multimeter or a suitable testing tool to measure it.

The Windows setup likely relies on a legacy MBR partition table, which is why CSM must accommodate it. Changing the installation format to GPT or completely removing CSM should resolve this issue. It’s puzzling why CSM continues to disable itself despite uncertainty.
