    Horizontal black bar flickering on screen every 10-30 seconds


    I have recently built a new pc and I get horizontal bars flashing on my screen every 10-30 seconds. The colour of the bar is usually black however it has been white a few times.I have all the latest graphics drivers so I do not believe that is the issue. I also don’t believe that it is an issue with my monitor or cable as I have swapped them both out and I still have the issue. The odd thing is that I don’t believe this occurs during playing games however it could just be me not paying attention enough to it. I have asked many friends and they do not know the answer to it. I hope one of you can help!

    :)

    Flickering and Black screen

    i was trying to save an image when randomly my computer when black and all my tabs were invisible. I couldn't see anything on my taskbar or desktop and every 30 seconds to a minute my screen would go black then back to normal in less than a second. I turned
    off the computer and turned it back on and I was taken to the log in screen, when I logged in I was just brought to the same problem. I'm able to open task manager but thats about it and it'll close sometimes when the screen flickers. I have a Windows 10 portable
    all in one computer, I need help.

    ***Original title: I have no items on my taskbar or desktop and my screen keeps flickering to black every 30 seconds***

    Screen starts to flicker after logging in for a while

    Hello

    This is an entirely new issue. My screen starts to flicker after logging in/turning on computer for a while, and/or if I launch an app that uses my Nvidia card (my laptop has Optimus), I'm not exactly sure which of these two causes it. For the first while after a restart, the screen appears fine. The flickering appears on desktop background + internet browser as well, so I'm pretty sure it's not a program compatibility issue. The flickering is not severe (the type that looks like horizontal bars sliding up) but it's an annoyance.

    Tried:

    • Disabling Windows error reporting + problem reporting service in msconfig
    • Restart computer
    • Resetting Nvidia global settings to default in Nvidia control panel
    • Checking for display drive updates in device manager (all up to date)
    • Checking monitor refresh rate (60Hz, can't be changed)

    Laptop I'm using:

    • i7-4700MQ 2.4GHz
    • 1900x1080
    • Intel HD 4600 + Nvidia GT750M

    Thanks for suggestions.

    Horizontal black bar flickering on screen every 10-30 seconds

    Screen flickers every 30 seconds

    My laptop screen flickers every 30 seconds. This is after the latest Windows 10 update. I had this the last time I had an update and it was to do with an app that I had to try and find and uninstall. I can't find an app at the moment so is there an easy
    way to find the corrupt app?
