The reason I asked about the CD drive is that a hard disk test CD can be made on another computer. Hard disk failure is high on the list of possibilities. See here:
However, once the CD is produced you have to power on with it in the drive. It will only see the CD if it is set before the HD in BIOS. It might already be set that way but most likely it is not.
Page 24 to 30 in this manual show the BIOS screens, page 29 being boot order:
Let me know if you want to pursue the above further.
EDIT: By looking at page 29 right now you could see if the HD is even showing - if it isn't then it has failed completely. Just exit without saving
Always pop back and let us know the outcome - thanks
