Identifying problems in Windows Device Manager​

Chances are you need a driver from your operating system disk (or from Dell) if redetecting the device does no good.

EDIT: Here's a link to the Dell forum with the same problem...

SM Bus Controller driver​

If you click on the Dell link I posted in (parentheses), enter you tag number, or let Dell analyze your system for updates (best done with Internet Explorer). Sounds like you may need to download and install an Intel chipset driver.

 

Try this: On that computer, go to this Dell Optiplex 745 Drivers & Downloads page and click the "Analyze System for Updates" button.
