I've recently completed my first PC build, and everything was going smoothly until I attempted to update my security settings to TPM 2.0. Now, I'm facing a black screen with no cursor. My setup includes an A520m-hdv motherboard, two 8GB DDR4 RAM sticks from Xpower, a Ryzen 5 5500 CPU, an MSI Mech RX 6600 XT GPU, and a Samsung ultra-wide monitor. Before the update, everything worked just fine. I've tried various troubleshooting steps like unplugging the PC and removing the battery for four days, reseating the RAM, initiating a reset with Shift + Control + Windows + B, and testing with two other monitors using different cables. I even replaced the GPU with a 5060 Ti since the original fan wasn't spinning, but I'm still stuck on a black screen. The RGB lights are on and the fans are working, but it seems like I can't access the BIOS or get the keyboard to respond. Is my PC completely bricked? Any advice on what I can do next?

Just to clarify, did you check to see if this motherboard requires a special procedure for BIOS resetting? Sometimes it needs more than just removing the battery, like a jumper or shorting out specific pins.
I found a link that might help! It discusses some troubleshooting steps to follow for situations like yours. You might want to check it out: https://www.reddit.com/r/techsupport/s/jGIkVlNcpv
How exactly did you perform the TPM update? Did you change any BIOS settings or just go for it? This could help diagnose the issue better!
I changed the security setting in the BIOS and then restarted, but it all went downhill from there.
Have you considered reflashing the BIOS? If your motherboard has a feature for BIOS updates without power, that might be your best shot!
You mentioned you've tried removing the CMOS battery for a few days, but have you checked if your motherboard has a jumper? That could sometimes help reset everything back to safe parameters.
I haven't seen that yet. I guess pulling the hard drive for a fresh startup could be worth a shot.
