To cut a very long story short, I took my computer to a store nearby because I could not get the wireless modem installed on it. The guy there said it needed system pack 2 installing as it only had system pack 1. This did not solve the problem with the modem, which has since been rectified by obtaining a new modem that works! however, ever since on start up of the computer found new hardware window comes up, one for multimedia audio controller and one for unknown device. When i select to let windows intall it says it can not find software. Help!
