ok sorry guy for not responding so soon. your problem could be a number of things it could be that you keyboard is defective ( unlikely), it could be that some spam or something to that effect has corrupted you registry. there are ways you could check but i recommend that you just run a repair if you are using windows xp. that way you windows files are fixed and at the same time you registry is also repaired. dont know how you get that done on your particular netbook but i am assuming that it can be done since you said the xp was built in.
