    Random rapid screen flicker


    I'm trying to figure out why my monitor screen flickers, like it is having convulsions, from one window to another...it happens for about 5-30 seconds at a time randomly throughout my work day..and can occur when I am browsing, typing in outlook, or typing in word. I have switched monitors, cables, and it still occurs. The problem occurred with a previus laptop (ACER using windows 7) which crashed in Nov. It is now happening again with a new Lenovo desktop using windows 8.1. I bought a new backup battery and that didn't make a difference. I changed outlets and that didn't make a difference. Any thoughts?

    Is the common denominator the building where you use the Laptop? Does it not happen when using only battery power? I'd suspect some kind of power problem in the building if the above assumptions are correct. If not... never mind.

    Thanks for your suggestion. Actually I am now using a Lenovo desktop computer for three months following the crash of my Acer laptop in November. The same thing is happening now with the desktop computer as was happening with the laptop. Crazy, random image shake...back and forth flashing the open windows...extremely rapid so that you see. I live/work in a house. I have the computer connected to a backup battery...just got a new one... I switched yesterday from one outlet to another...but that didn't seem to make a difference.... there are also little unstable things I am seeing with various programs, such as not being able to open the browser when using outlook and clicking on the browser icon (chrome) in the task manager, or perhaps in some internet site and wanting to go back to Wordor Outlook and clicking on the icon in the task manager...these are random things and I can't get a grip on why happeniing....

    I would start looking at building power, if it is happening with different units. Get a Kill-a-volt or use a DMM (Digital Multi-Meter) to check what the voltage is at that outlet. You can call your power company, and they will actually check the incoming power to the meter, and also check inside the building at the Main panel.

    If they find a bad or corroded Neutral from the Power Pedestal or Pole drop, they will fix it to the meter. If they find the problem is from the meter to the panel, then it is up to the building owner to hire an electrician.

    If you do not know how to use a DMM to check for voltage, there are videos on Youtube to show you how to use it. Just be careful if you decide to check at the main panel. There is 120 vAC at each Leg, and can be more then 100 amps on each leg, depending on incoming power.

    Thanks for the suggestion...I had googled and regoogled the problem, and only yesterday found a reference to the possibility that speakers could be causing the problem...i have had the same old speakers (ungrounded) for many years....i unplugged the speakers and so far there has been no repetition of the flicker/shake issue....i am keeping my fingers crossed....and if that resolves the problem, then I will be a happy writer. It's been disconcerting to have screen convulsions occur randomly throughout my work day...and it may have contributed to my laptop crashing last november....anyway...thank you for your suggestion...I will follow up on it if the speaker disconnect doesn't resolve the issue...but now, in this workday so far, no repetition...we'll see, and I'll report here for the record.

    I've had similar problems a long time ago , it was electrical interference from another source , in my case it was someone running something unshielded outside my house.

    Spikes from a neighbor's electrical usage? I guess anything is possible. I have the computer and monitor plugged into a cyber power backup battery...with surge protector....so am unsure how it could be an electrical issue....just had another shaker for about 20 seconds while in Outlook and about to reply to somebody's email....wondering if it could be some malware or trojan or whatever they call them that has gotten into my data since this happened with a previous computer (that crashed) and now is happening with the Lenovo desktop I bought as a replacement in November....Windows Defender scan doesn't turn up anything though...

    Cyber Power UPS are the worse ones. Get a APC. Even with a surge protector, you are still going to have issues. None will show if you have a corroded Neutral, loose or illegally connected ground wire between the ground & neutral on an outlet.

    I have a Ted5000 on my main panel. I started to see low voltages on my line, so pulled out the meter and found one leg that was consistently low every day. Called up the local utility, they saw that incoming was correct, put the meter back on, and the problem went away. It also gave them a chance to look for corrosion on the power wires & lugs, along with any burnt signs.
