I am fairly new to building my own pc and have had it for about 6 months. I recently upgraded from a Ryzen 5 to a Risen 9 5950x. I did not update bios before upgrading which was a mistake on my part. I couldn't get past a bios screen no matter what I tried with the new cpu so I tried installing the old cpu and then updating bios then reintstalling the new cpu and continuing but even with my old cpu, which worked perfectly fine before, I still couldn't get past a bios screen. I checked my boot configuration and set it to UEFI and that still wouldn't work. I gave up in worries of complicating it more and took it to a computer store for them to check it out. Im still curious as to if anyone has had this problem and was able to get it fixed, and if so how? Please let me know.
