I put my PC playing a video around 4 days (without any operation),
The screen content freezes,
the syslog says
“Unable to determine the device handle for gpu 0000:01:00.0: GPU is lost. Reboot the system to recover this GPU”

Could somebody help?

Might be overheating, failure of power supply or defective hardware.
