i just doubled clicked the e button at the top and it all came back.
v v v v v v virus? i hope not. but is that the main reason settings change without yr say so?
what are o/s? original settings? how do i reinstall that? im using vista and everything was installed when i got it, dont think i had any discs or anything...i'll have a look. can you explain what i need to do? by reinstalling stuff do i loose other stuff? im a bit computer tarded
cheers!
