Hello, Soghpar I'm an independent advisor and I will try to help you today.
Regarding your query and according to what you describe, it is very likely that the system startup or some system file has been damaged. I suggest you perform the following actions:
You must enter the system recovery environment, but since you cannot access the PC, then you must force it to shut down. Complete the following steps:
- You turn on your PC
- Just when it is in that process, press and hold the power button for 10 seconds to turn off the device.
- Then press the power button again to turn on the device.
- At the first sign that Windows has started (for example, some devices display the manufacturer's logo on restart), press and hold the power button for 10 seconds to turn off the device.
- Press the power button again to turn on the device.
- When Windows restarts, press and hold the power button for 10 seconds to turn off the device.
Press the power button again to turn on the device. Allow the device to fully reboot to enter the recovery environment.
Then the computer should enter the recovery environment and follow these steps:
-Click on Troubleshoot.
- Click on Advanced Options.
- Click Startup Repair.
- Choose the current user account, if it asks for a password, enter the password and click Continue.
In case it doesn't work, try to restore the system. In that case, you must access the recovery environment again.
Now in the recovery environment, do the following:
- Click on Troubleshoot.
- Click on Advanced Options.
- Click on System Restore and follow the instructions.
