Windows and task bar flashing & system troubleshooting not working

HP Recommended
Microsoft Windows 10 (64-bit)

I recently upgraded from 8.1 to 10 home. I worked with no issues till yesterday. But since morning I have been unable to use or access the task bar icons.

Was not able to even shut down the laptop from windows icon. 

I Went to task manager and tried to restart the windows explorer. Since then cpu is at high level working and whole display screen is blinking.
