Sounds like a graphics card problem. Either overheating, connection issue, or end of life issues.
If a pc, time to do a 'de-fluff' of the interior and vents, fans. Check lead from case to monitor and if you have a graphics card fitted (rather than onboard graphics) check and reseat the card in the slot.
Also, make sure your graphics card drivers are up to date.

I give the inside of my computer and laptop a blow around with this every few months:

Clear the dust off all the cooling surfaces and vents to allow it to cool properly.
