I got a new cpu (Ryzen 7 3800x) and a new pc case, transferred everything from the old case (gtx 2070 32 gigs of ram asus prime b450M-A) to the new one and when I went to turn it on everything booted but nothing showed up on my monitors. I’ve tried every fix I could find so this was my next option hope you can help.
Have you updated your BIOS before installing the new CPU? If not, have you ensured the current BIOS support Ryzen 3000 CPU's?
You need BIOS 1201 or newer.
Not that I would recommend a Ryzen 7 on this board though..
