If you find yourself with a flashing screen after Windows 10 upgrade, there is a solution that might work for you. I am putting this tutorial together because I had a customer who experienced a flashing screen after the Windows 10 upgrade. After I logged in to the desktop, I was presented with a flashing screen. The system was paralyzed.
Compatibility of programs and hardware drivers with the Windows 10 upgrade can cause problems which can manifest themselves in various ways. The best place to start troubleshooting is in Safe Mode.
I am going to describe step by step on how to get into Safe Mode. I will describe the steps I took to fix the flashing screen after the Windows 10 upgrade.
While in Windows press
Press and hold down the Shift key.
Click on the Power Icon Button on the bottom right of your screen.
Click on Restart and continue to hold down the Shift key until the “Choose an Option” screen shows up.
Click on Troubleshoot.
Click on Advanced Options.
Click on Startup Settings.
Click on Restart, and your computer will reboot.
After reboot, the Startup Settings screen will appear.
Press 4 on your keyboard to Enable Safe Mode.
Log in to your account.
You are now in Safe Mode. If the flashing screen doesn’t occur in Safe Mode, then we can assume that it is a driver issue or a program running at startup that is causing the flashing screen.
A good way to find out if it is a third-party program or a driver is to perform a clean boot. I have already written about this. Go to Clean Boot Windows-Troubleshoot Software Conflict and follow the instructions.
Additional Steps to Fix Flashing Screen After Windows 10 Upgrade
Two additional steps you can take is to uninstall your anti virus program and graphics driver.
Norton Anti-Virus: Uninstalling Norton worked for me. You need to use the Norton Removal Tool. If this fixes the flashing screen after Windows 10 upgrade, then you can reinstall it again with a newer version. If you transferred Norton over from your previous Windows OS to Windows 10, I would start here first.
Graphics Drivers: Graphics drivers that worked in earlier OS might not play nice with Windows 10. Updating the graphics drivers has worked. You can uninstall graphics drivers from Programs and Features in Control Panel. This will force Windows to install generic drivers upon restart. If this fixes the flashing screen, then you can run Windows Update to install new drivers.
Another option is to go to your computer manufacturer’s website or graphics card vendor to find your driver.
Hopefully when you get into desktop the flashing screen after Windows 10 upgrade will no longer be a problem. If the problem persist, then it is likely that your PC is not compatible with Windows 10.
