Question Old CPU & New CPU both giving black screens HELP

[Tylr]

I just bought a Ryzen 7 5800x to replace my Ryzen 5 2600. I originally thought I had to download a new bios and install it after I installed my new cpu, but of course I was wrong because you're supposed to update your bios before putting in the new cpu. When I had the new cpu in, my screen was black so I tried to do a bios flashback which ended up doing nothing. I then tired to put my old cpu back in which led to the screen being black once again. I'm lost and frustrated and would appreciate any solutions anyone has! Thank you! (I have a MSI B450M Gaming Plus)

Looks like you got a corrupted BIOS, did you follow instructions exactly ?

Might first just try a clear cmos and then test with the old cpu in.
