Hi

 

Run a diagnostic if you can to test the hardware.

 

Did you clear the CMOS/BIOS settings?

If you need a recovery disk, perhaps here?


A 3rd party downloader like…

If in doubt please ask.

Hi

 

Why would you press the yellow button?

 

You may need a new hard disk, operating system or computer.
