This morning I switched my pc on and TuneUp Utilities notified me that one of the system devices may not be working properly. I checked the device manager and saw an exclamation mark next to the 'pnp bios extension' device. I double clicked it and this was the message in the device status box: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) Click Troubleshoot to start the troubleshooter for this device." I tried updating the driver but I got the following message: "The wizard could not find a better match for your hardware than the software you currently have installed" Ideas anyone?
