Sony Vaio CS190 laptop drivers

hey even i have upgraded to windows 7 and my model is VGN CS26M (Sony VAIO). even for me the capture button is not working and touch pad is also not working...
i am really getting frustated, please suggest,
from device manager, it says bluetooth peripheral device missing. i tried downloading from sony website Bluetooth driver 6.2.0.9600.0908210. but even in that i got error in installing.

Those are good answers but you dont need them all you have to do is wipe the systom and install windows because they will make you pay out the *** for the driver expshely if your comeing from vista to xp they hate that because they lose money..
