Sometimes users' screen going blank, it work only after reboot

I am a system admin at a school and where I manage about 130 workstations in which all of them are Windows 10.

The problem I am getting reports of is users’ screen going blank and the screens going onto standby and the pc not being useable anymore until its re-booted. The screens act is if the pc has been shut down and says no signal detected. Occasionally I am near a pc and will press Ctrl + Shift + Windows Key + B and this sometimes works and brings the screens back.

Looking at the system logs after the pc has been restarted I can see the logs show Windows Successfully diagnosed a low memory condition and lists savservice.exe and svhost.exe. But I don’t think that this can be the cause of the problem.

The issue doesn’t seem to be triggered by a certain program or application being run, it can be mid-excel or web browsing then bam screens have gone onto standby. I have installed the latest graphics drivers to no avail.

I hope someone can help me try and resolve a problem that seems truly random in its nature.

Edit: I have attached similar screenshot
