How to reinstall drivers on windows xp on a emachine notebook

Hello,

I have an emachine model number KAV60 eM250 series. When ever i turn it on it goes to the safe mode propmts and when i select one it boots up windows XP for awhile then the screen goes blank? Acomputer store said I need to restore the computer as drivers etc are stuffed or missing bits (thanks kids) but as this model does not have a cd drive how can I get this working...
