A computer "Controller" that controls several screens has separate GPU Cards attached. after weeks of running smooth screens attached to "a card" will fail showing no signal and black screen, few days after, other screens that are connected to another card will fail.

Restarting the computer fixes the issue immediately.

How can i troubleshoot the issues to see temperature, ram, errors etc?

System is using windows.
