Windows 7: Msg: Fail to find and install unknown device driver

Msg: Fail to find and install unknown device driver

Windows 7 installed for almost two years. No new hardware installed. In last few days get message above when I turn on the computer at beginning of day. Looking in list of devices shows only Unknown device with no description. Nothing seems to be malfunctioning. Where should I look to fix whatever is generating the message?

Thanks, Bob

If the Computer is working fine then it is best to disable the pesky device that keeps asking for the driver in the Device Manager.

After that open the Device Manager (Control Panel\All Control Panel Items\System) and send its screen-shot with the unknown device expanded to help in determining what this device is.

Thanks, W.
The Device Manager showed only "Unknown Device".
I seem to have found a solution that so far has worked. I performed a System Restore to a point a few days ago prior to when this message appeared. Since the Restore, the message has not reappeared and the Device Manager no longer lists an Unknown Device, and all the applications and hardware work as usual.

Try updating your chipset. Sometimes with MS updates, you'll get an update that will cause this type of error. That's because it's using some generic driver update. Usually, an updated chipset driver will do the trick. This has been my experience in past situations such as yours. Then a BIOS update might be in order as well, to be compatible with future hardware and updates. Either couldn't hurt.

I've looked into that for a problem I had with the dvd drive not recognizing dvds. It turns out that there is no further update to the chipset for my computer beyond the one I already have.
As I mentioned above, this problem seems to have been solved via the System Restore route.

Thanks for your attention and suggestion.
