I cannot do any of the ram or hdd tests because the computer will not boot up.
As I mentioned the first recovery disc was OK but the second did not complete.
I made a new Disc 2 but still it will not accept it and will now not even start or go as far as 95% as previously.
I am at a loss to know what to do next.
Because the computer will not boot up it is impossible for me to do other than keep trying the recovery discs which seems futile.
