Force Shutdown your PC using the power button. When rebooting, keep pressing the F8 key (Function key 8) before the windows logo appears. Select ‘Start Windows in Safe Mode with Networking’.
After restarting your PC in Safe Mode perform the following methods to solve the problem.
Run Event Viewer From Command Prompt
The Event Viewer tool in your Windows system maintains logs of events, programs, and security events on your computer. You can use the Event Viewer to gather information about hardware and software problems and also manage event logs.
The system tool starts automatically during Windows Startup and logs every installation and update on your system.
