@Ruby994 Welcome to HP Community!


I understand that you are getting a 3F0 error.


In that case, I would suggets you perform the recovery.


1. Shutdown the computer.  

2. Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.  

3. Press F11 once for System Recovery.  

4. Choose the Keyboard Layout.  

5. Click on Troubleshoot.  

6. Go to Recovery Manager and click on System Recovery.  

Note : Back-up all your data as System Recovery will delete everything that you had saved or installed on the computer.
