If you find yourself with a flashing screen after Windows 10 upgrade, there is a solution that might just work for you. I am putting this tutorial together because I had a customer who experienced the flashing screen after Windows 10 upgrade. After I logged in to desktop I was presented with a flashing screen. The system was basically paralyzed.
The only way to troubleshoot the flashing screen after Windows 10 upgrade is to get into Safe Mode. The biggest issue for end users is how to get into Safe Mode when the computer is not responding.
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 Windows 10 upgrade.
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.
Login to your account.
You are now in Safe Mode.
The good news is that if the problem 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.
In Safe Mode you will be able to uninstall the offending program or uninstall the faulty driver. There have been various reasons given about why the flashing screen after Windows 10 upgrade occurs. Scouring the Internet the same ones kept popping up as probable causes. Here is a list of possible programs that may be causing the flashing screen.
- 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.
It is probably a good idea to uninstall your current Anti-Virus software and reinstall it after the Windows 10 upgrade.
- Apple ICloud: Disabling the service from startup or uninstalling it has worked.
- Fingerprint Scanner or Biometric Devices: Disabling the service from startup or uninstalling it has worked.
You can disable Apple ICloud and Fingerprint Scanner from the Services Console. Follow the instructions below to disable services in Safe Mode.
- Graphics Drivers: Graphic drivers that worked in earlier OS might not play nice with Windows 10. Updating the graphic drivers has worked. You can uninstall graphic 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.
Other option is to go to your computer manufacturer’s website or graphics card vendor to find your driver.
Additional Steps to Fix Flashing Screen After Windows 10 Upgrade
If none of the above solutions worked for you then try this as a last resort. A temporary workaround that I used in the beginning was to disable two services; Problems Report and Solution Control Panel Support and Windows Error Report Service.
This solution is a temporary workaround which will allow you to get into desktop. The reason I say temporary is because these two services are needed by Windows. I don’t believe these two services are the real problem to flashing screen after Windows 10 upgrade. But it will allow you to investigate further and track down the real problem.
Disabling these two services allowed me to get into desktop. Later on, after I uninstalled Norton Anti-Virus, I turned these two services back on and I didn’t have the flashing screen. This led me to the conclusion that it was Norton. I reinstalled Norton and everything was working normal.
Steps to Disable Services in Safe Mode
Press the Windows Button + the r key to bring up the Run Command box.
Type services.msc and press Enter.
Scroll down to Problems Report and Solution Control Panel Support service.
Right click on Problems Report and Solution Control Panel Support service.
Click the box, next to Startup Type, to show the drop down menu and select Disabled.
Do the same for Windows Error Report Service. You can also disable Apple ICloud Service and Fingerprint Scanner Service from here. When you’re done, restart your computer.
