hey bthanks for replies.
bob, your machine is other dimension, dont compare it with computers.. makes me sad.

i looked at some sites, they all said tht the processor i have runs 64b. loose the fn keys doesnt matter if the system runs stable and fast. the bad thing is back up all stuff and load the new os (could i copy things on a particion forex D: or do i have to format the entire hd?)loose all progs isnt problem neither, i just have a lot of lil freewaretools.
would run a win 7 32 more effecient on my laptop than 64 version?
would any of them run more effecient than my vista homepremium??
