You start your computer.
It goes into setup.
You press esc
Then discard all changes.
Lets stop here:
If the computer goes into setup some thing is wrong.
If you discard any changes nothing is fixed.
A message of a jumper being returned to it's normal position.
You have two hard drives.
Were both hard drives installed and working before this problem or after?
You installed second hard drive and they are on the wrong ribbon connection or the jumpers are wrong.
Your computer sees the problem and is trying to fix it's configuration but you keep discarding the changes.
Perhaps I misread your post...
