Just looked at that site Mr Happy & didnt find anything about PC World.
I am interested as my daughter is at Uni & phoned me to say she has a problem on her laptop. She went to PC World & they offered to backup her hard-drive (£30) reload Windows (£200) & provide a (???? @ £50) to enable her to transfer files from her laptop to another machine.
I told her I will sort it myself when she visits this week-end.
For £280 we can practically buy a new m/c (hers is 2yrs old).
