I understand the issue you have, there is nothing to worry I am here to help, have you noticed any changes before the issue starts? have you installed any hardware or software that may trigger the issue? while waiting for your response, kindly follow the steps below:
Before doing the steps, make sure to remove all peripherals connected to your PC and just retain the Mouse, Keyboard, and Power source.
Press F1 then click Troubleshoot> Advanced options> System restore - Follow the prompt and choose the date when it was working fine.
Note: If you cannot see or go to System Restore, kindly follow the steps below:
Restart the device 3-5 times until you reach Windows recovery mode, wherein you have the option to select Continue, Troubleshoot, or Exit.
Or try to Press and hold the Shift key while continuously pressing F8 while starting the PC
Then on Windows Recovery:
