I installed Windows 7 and the Base System Device has a yellow exclamation and the driver for it is missing.

Windows update has been unable to find the missing drivers for the device to install. Meanwhile my integrated touch pad and left mouse has stopped working. Are they connected?

I have a Sony vaio. How can I fix this problem?

when I had this issue, the driver for the SD card reader was missing. – magicandre1981 Dec 7 '12 at 16:44

Go to the Sony Support page for your laptop and download all drivers you can find. – magicandre1981 Dec 7 '12 at 17:00
