I'm trying to install Windows 11, and I've made some changes in the BIOS. I disabled CSM and turned on TPM 2.0 without any issues. After rebooting, I tried to enable secure boot which resulted in some PK key errors, but I managed to fix that. However, after saving and exiting the BIOS, my PC now beeps five times (which indicates a CPU issue) and I get no signal on my monitor. I've already tried switching between DP and HDMI outputs and even plugged the HDMI into the motherboard instead of the GPU, but nothing seems to work. What should I do?

It sounds like you've run into a common issue with enabling secure boot. Sometimes changing BIOS settings can lead to losing access to your display signal. Have you tried resetting your CMOS? You can do this by removing the battery on the motherboard for a few seconds and then putting it back in. This often helps clear out any glitches from BIOS changes.
Make sure your drives are compatible with secure boot. Secure boot generally works fine with SSDs and M.2 drives. If you're using an older SATA drive, it might be the cause of your issues. You mentioned your OS is on an SSD, so that should be fine, but double-check that it's set up correctly in the BIOS.
Right, as long as your SSD is functioning well, it should support secure boot. Just ensure all connections are tight and try updating your drivers if you get access back to the BIOS.
Definitely! Just make sure the PC is off and unplugged before you take the battery out. It usually takes just a moment, and it can really help reset any weird issues you're having.
