Well I've made it back! I did a format then b4 installing any drivers for MB, graphics, sound card etc I updated windows first including Sp2. At this stage all seems fine but I'm yet to install any games! I now have all hardware installed and things seem ok but it is early days yet. But aleast this time I have made 5 Ghost Images along the way so I can revert back to a pre Sp2 installed system if I have to!
And just a little message for 'Luciel' "Ha I beat Valve"

(he knows what I'm on about!)
