Hi,

A 5:3 error code indicates a System board problem: The embedded controller times out waiting for the BIOS.

Have you checked that the latest drivers, especially the Nvidia graphics drivers are installed?

@ex calibur

Can you force the laptop to use the Intel graphics and not the Nvidia and see if the problem occurs?

if it doesn't then there may be a problem with the Nvidia GPU.

Also try running the hardware diagnostics to check what it shows, especially the video checks
