  • Hi, 

    Since this issue just happened recently, we can try to restore your system back to previous point and see if it can work fine:

    This option takes your PC back to an earlier point in time, called a system restore point. Restore points are generated when you install a new app, driver, or Windows update, and when you create a restore point manually. Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.  


    1. Select the Start  button, type control panel and then choose it from the list of results.
    2. Search Control Panel for Recovery.
    3. Select Recovery > Open System Restore > Next.
    4. Choose the restore point related to the problematic app, driver, or update, and then select Next > Finish.
    Note
    If you’re not seeing any restore points, it might be because system protection isn’t turned on. To check, go to the Control Panel, search for Recovery, and then select Recovery > Configure System Restore > Configure and make sure Turn on system protection is selected.

    We can also consider that this could be Hardware issue. Would you please contact Acer support for Hardware check?
