Monitor Problem???

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

My main computer runs  Debian Buster and is displaying some unusual 
behavior.

The monitor is blanking, without warning, at random times, and restoring 
the screen  while I working. There is no warning, nor does the computer 
seem to be overheating (I continuously monitor the temperature).

I rather suspect that it may be a hardware problem. I keep the software 
up to date.

I am querying this group because I can't think of a more knowledgeable 
source. Any thoughts and suggestions of things that I might be able to 
test will be very welcome.

Thanks in advance.
