Computer Causes Monitor to Intermittently Black-Out in One-Second Intervals

HP Recommended
Hewlett-Packard Pavilion HPE
Microsoft Windows 10 (64-bit)

Since installing Windows 10 (approximately eight months ago), my Hewlett-Packard Pavilion HPE causes the  display monitor to "black-out" in one second intervals; when the monitor "blacks-out," the condition is accompanied by an eerie "beeping-and-bonging" sound. At times, the Hewlett-Packard Pavilion HPE desktop computer will make a SERIES of "beeps-and-bongs"; however, when it makes the series of "beeps-and-bongs," it will not "black-out" the monitor. It is NOT a cyclical condition: in other words, the described condition is very unpredictable.  Additionally, there is NO rhyme-nor-reason to the symptom’s predictability.


At times the described condition will happen 5-6 times per hour; at other times, it will NOT happen for several hours. But, I can just about guarantee that if the computer is left in the “ON “position, it will eventually happen. During the time I typed the previous sentence, the computer made two (2) series of “beeps-and-bongs.”


Not only is this condition incredibly annoying and frustrating, but I’m concerned that it is a symptom of a much, much more insidious “root-cause” condition, and that this computer will eventually have a catastrophic failure. And, yes, I do have all my data, etc. backed-up.


I know that this condition is NOT being caused by the monitor, since I purchased a brand new Samsung 27 Inch Curved Screen Monitor just two weeks ago. I made this monitor purchase after spending countless hours researching and diagnosing this technical concern.  


After connecting the Samsung 27 Inch Curved Screen Monitor, the same eerie, weird condition I previously described continued, unabated.


I've already installed the updated drivers for the system's video card.


So, I'm making a very educated guess that it must be an internal computer problem.

Based upon the type of technical problem I'm experiencing, it's just about impossible to troubleshoot / diagnose it with a Virtual Assistant. No offense, but I really do need to explain my technical problem to a live human being—and , preferably, a qualified Technical Support Engineer or Technical Support Technician.


I've never really been able to solve a technical concern by "talking" to a Virtual Assistant.

I reviewed your post and I understand that you are facing issues with the display on your computer.


Don’t worry, I assure you I will try my best to get this sorted.


I recommend you update the BIOS from the below link and check whether the issue is resolved.


If you continue facing the issue, then boot to BIOS by tapping continuously the F10 key while restarting the computer and check whether you can duplicate the issue in the BIOS screen.


Let me know how it goes and you have a great day!
