I feel your pain Ady. I had some trouble with Gateway a few years back (my PC wouldn't read my CDs properly). I was about 11 anyway so my dad tried to find out what the problem was and it turned out that we had a faulty hard-drive. I forgot what answer my dad got in terms of 'how to deal with it', but it must have been a bad one.
Hope you're all set for a great x-mas mate, I still need to buy 2 presents :O
Oh and I've signed the new petition for proper remasters of the OT btw (I'm number 248 - with a rather lengthy comment to Mr Lucas) :D
