This guide will help you to resolve this Blue Screen error on Windows 10/8/7.
1] Update your drivers
Check with Windows Update, and see if there is an update pending which relates with your Device Drivers. If necessary, you can always install them manually from the OEMs website.
2] Check Device performance and health
Open Windows Defender Security Center, and check if there is a yellow explanation icon against Device performance and health. Click on View report. You might see Health Report pointing towards Storage Capacity, Device Drivers or Apps and Software.
3] Run ChkDsk
If the error is related with Storage, i.e. hard disk errors, you need to repair it. You should run chkdsk in the command prompt to resolve those issues.
If this cannot solve your problem, you may have to think about replacing your hard drive. When you do so, make sure to backup all your data on the Windows 10 PC. You can also use it as a secondary hard drive.
4] Increase the size of the Hibernation file
Open Command Prompt as administrator and execute the following command:
powercfg /hibernate /size 100
The default size is 75%, and after running this command, it will be increased to 100%
Does this help? If not you may reverse this.
5] Run Troubleshooters
Run the following command to open the Performance Troubleshooter:
msdt.exe /id PerformanceDiagnostic
Once it is opened, run it.
Run the following command to open the System Maintenance Troubleshooter:
msdt.exe /id MaintenanceDiagnostic
Once it is opened, run it.
You may also run the Blue Screen Troubleshooter. The built-in Troubleshooter is easy to run and fixes BSODs automatically. The online Windows 10 Blue Screen Troubleshooter from Microsoft is a wizard that is meant to help novice users fix their Stop Errors. It offers helpful links along the way.
6] Run Windows Defender Offline
You can scan your PC offline using Windows Defender to find out if any malware has affected your PC.
7] Uninstall recently installed Software
If this problem occurred after installing new software, you need to install it. Open Settings > System > Apps & features. Select Sort by name and change it to by install date. Change it to the recently installed app you want to remove, and then select Uninstall.
8] Disconnect external hardware and USBs
Make sure to remove any connected & external hardware when upgrading or updating. Many a time Windows update gets stuck because it tries to get a driver for the connected hardware which can be done later.
All the best!
