Probably the system is out of memory.  Usual cause of that is having too
many progs running in the background, or even just one prog which might be
a resource hog. Close everything you're not currently working on. Most
people have too much running automatically at startup, then wonder why
performance slows or stops.

It's not likely to be a monitor problem.

When asking for help, always state what OS you have, and basic computer
details.  Without that info, we can only generalise or guess.
