Yeah it's not a great advert! And I do feel bad saying anything bad cos he actually seemed like a really nice guy but the fact is that one of them at the very least either doesn't know what they are doing or is being dishonest, as they have both diagnosed a different problem to each other. Either way it's not good, you should be able trust people. I'm going to try the mouse when I get in and I'll post back. The computer needs fixing whatever tho and it doesn't seem like a very good idea to use either of these so can anyone recommend anywhere, like is pc world any good, or is it mega expensive?
