A couple of weeks ago the monitor (HP 2509m) on my computer (HP p6367c) died on me.  The monitor had a flickering problem for a year or so (the flickering would last anywhere from a few minutes to over an hour before it stopped), then it would only display (accompanied by a hissing/static type of noise) for a few seconds before going black (the monitor did not turn off though).

 

Afterwards, I used the monitor (same model as the one mentioned above) from my Mom's computer.  Less then 24 hours later it too had died (it suddenly turned off without warning and won't turn back on).

 

I tried plugging the monitors into different outlets with no success.  Both had been plugged into a IBM Office Professional OP 500 backup power supply.

 

I'm currently using an old CRT monitor on the computer (no problems as of yet).

 

Is it just a coincidence that both monitors died within a short period of time or is it possible that something else (like a faulty video card or electrical issue) caused the monitors to die?

If these two monitors were of roughly the same age you may have just been unlucky. Have a look at this topic from the HP support forums. This model of monitor appears to have a history of build quality problems leading to relatively early failure even though its image presentation seems to have been good. If nothing else, it may divert your Mum's wrath !

The fact that your computer is working with this other monitor suggests that your video card is OK. Electrical issues are a possibility with thunderstorms as the most likely candidate but you feed it through an auxiliary supply so that should counter any normal surge. And a thunderstorm close enough to overcome the surge protection you would not have missed !

Thanks for replying.

 

I got a new monitor (LG Ultrawide 25UM65).  It worked fine for a couple of days, but the sound stopped working today.  I tested the monitor on my Mom's computer, but still no sound (using a different cord didn't work).  Other than the sound not working, everything else is fine.  Is there any possibility a virus (or something on the computer) has been causing these problems?

I'd suspect possible power issues.  Have you been having issues with your power?

No known problems (at least not around the time the monitors quit working) and nothing else that's plugged into the same outlet as the monitor has experienced problems.  The old CRT monitor is still working.
