I configured a platform key (PK) and turned on Secure Boot, but now my PC won’t start.

Hello everyone, I'm trying to see if my PC can use secure boot for Windows 11. I opened the BIOS (MSI UEFI Click 5) and attempted to enable it. It asked me to be in a specific user mode and provided a platform key. I set that up automatically, then turned on secure boot. After saving the changes and restarting, my PC didn't boot into the BIOS at all—it just started up normally, fans spinning, but no image appeared or the monitor registered anything. My system details are: MSI B550-A Pro with UEFI Click 5 (not the latest version Rysen 3600 GSKill 16 GB 3200 Hz MSI GTX 970 1 TB Corsair SSD 2 TB HDD). I tried resetting the CMOS by removing the BIOS battery for 15 minutes, but it didn’t work. I also unplugged my SSD and HDD to check if they showed up in the BIOS—still no luck. The EZ Debugg SSD on the motherboard connects from CPU through DRAM to VGA and then exits at boot, with the boot process still active. I’m really unsure what to do next since I can’t access the BIOS. Help would be greatly appreciated, or maybe I should take it to a repair shop?

Turn off the power supply unit. Disconnect the CMOS battery for five minutes. Unplug any SATA devices, including two hard drives. Restart the system.

I can't add my bios to turn it off. Please forgive me if I messed up the post—I assumed it wasn’t meant to show the BIOS entry option.

I face the same problem as him. I'll test your solution after work.

There was another issue... The CMOS battery (marked Bat1 near the JBAT1 jumper) was taken out for about 15 minutes, and no storage device was linked via SATA, USB, or M2.

It seems you're troubleshooting a battery issue. Make sure all connections are secure, reinsert the RAM and GPU. Adjust the settings by pressing Del during posting—your screen might be on even if the PC is active. Is it HDMI or DP?

Verify the monitor input. (Display cable and selected monitor are being checked.)

Yes, I turned off the power cord during the process.

While working on my case, I unplugged the PSU and kept the power button pressed for a while. Since I didn’t have a grounding cable, I touched my radiator before starting and every few minutes. After reinserting the GPU and RAM, most connectors were gone—just fans and USB ports. Still, nothing happened. How can I confirm if my PC is running but not showing anything? I can’t access the monitor settings because it won’t turn on at all (it’s an old Acer with a DVI cable).
