My 'PnP BIOS Extension' device may be corrupt

  1. 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? :confused:

    I actually did have daemon tools installed. I hardly use it, I prefer using alcohol. I uninstalled daemon tools and my problems were solved :grinthumb. Thanks for your help man.
