Hello. My name is ***** ***** I will be assisting you today.
Can you press F1 repeatedly on startup to get into the BIOS?
If you press the num lock or caps lock does a light turn on they keyboard?
sounds like you need an external keyboard to be able to do some more testing.
Do you have a blank DVD we could burn Windows 8/10 to and reload everything?
you put dvd and press F12 repeatedly on startup, anything different?
