I have gone through your Post and would like to help
I suggest you run a System Test to confirm the Hardware Functionality first
- Shut down the Notebook completely
- Turn it back on, then tap the Esc key repeatedly until the Startup menu screen is displayed.
- Press F2 to select System Diagnostics.
- Click System Test
If all the Tests pass, try a System Recovery using the Recovery Media.

I appreciate your efforts to try and resolve the issue. I would suggest performing system factory reset will put the computer back to the original factory settings in this way all corrupted and outdated software will be removed.
While doing the recovery there is an option to backup your personal files. If you have not previously done one now is a good time.
