  1. This morning my computer was working fine, but then I restarted it to update, it restarted but then the monitor turns black and the computer makes a long, continuous ‘flat line’ type of beep. I’ve looked up multiple solutions but none of them work, so I’ve come to this forum for help.

    Hi You stated that you restarted your computer to install update? What update? Are you running W10? What are the multiple solutions you have tried. Do you have any installation media. You can find the media here that you can create and use to repair or reinstall windows.

    Confirm that you do not have a depressed key or mouse button.

    Hi! Can you boot into safe mode??Can you get into Advanced Start-up Mode.

    1. Start your computer and follow the POST, when Windows should begin loading, press the power button to shutdown your computer.

    2. Repeat the previous step twice, and in the third restart the operating system should enter into the Windows Recovery Environment (Windows RE), where a number of diagnostics will be performed to try fix any booting issues, but you will also get an option to access the Windows Startup Settings.
