I have a AsRock B550M Pro4 motherboard and I switched on Bitlocker (yeah I know big mistake). I think I may have fast boot switched on too in BIOS.

Bitlocker prompts me for a password but my USB keyboards don't work. I've tried give different keyboards. I also cannot get into the BIOS so I'm locked out. I need to get back in or lose valuable data.

Any ideas?

So I tried to clear the CMOS by shorting the CMOS jumper. I don't know where the jumper cap is so I just used a screwdriver to short it for 3 seconds. When I power on the PC now nothing is displayed on the screen.

I changed from my GPU display port to the onboard display port, but still nothing. The PC powers up and all the fans spin but nothing on the display now.

To troubleshoot further I attached a speaker and I get five short beeps.
