thks for the answer. but you see the problem with my laptop is that the harddrive is starting to breakdown. windows has frozen a few times because the harddrive just simply stoped so knoppix is great cause being a live cd linux it doesn't need the harddrive to work so i'm fine with it...
so my guess is that if i install another os in the HD the problem will not go away. guess i'm not gonna be able to have wireless internet on my notebook!
but thks anyway!
