Hi, we have our laptop for 3 years, constantly having problems with it. The best solution we find is to reinstall system from recovery disc. After the last reinstallation and updating with service pack 2 we can't use any hardware via usb (apart from mouse). The computer detects the hardware but can't run with it; updating drivers doesn't help; device manager still shows yellow exlamation mark. Could you help us? We don't want to reinstall system again to get drivers work properly
