I went from a 2600x to a 5600 (yes, MoBo is compatible after BIOS update) and now for some reasons I get 1FPS in games and monitor is not really detected (resolution is fine, but I can’t change refresh rate and in “color” settings it’s shown as “None-1 Monitor”).

I tried:

  • monitor factory reset;
  • updating GPU drivers (was already running latest);
  • removing and purging GPU drivers (sudo apt remove ~nnvidia and sudo apt-get purge nvidia*) and reinstalling (sudo apt install pop-desktop system76-driver-nvidia);
  • resetting RAM speed to factory (2400Mhz).

Still nothing.

As you can guess from the commands, I’m running PoP!_OS and a nVidia GPU.

What else can I try?

Thanks in advance!

Issue found: I disabled secure boot from BIOS and now I can change resolution and refresh rate. Since I updated BIOS just before installing the new CPU it went under the radar

      FWIW, your UEFI is generally likely to reset with significant hardware changes (system memory, CPU). It’s generally fine with video card, disk and power supply swaps so long as it doesn’t boot into a stop code as a result.
