Read this, "How to reinstall drivers in the correct order"

* Go to the File Library for your system model
* Change the operating system to Windows 10 if it is not already chosen
* Open Chipset
* Install each one, one at a time, restarting the laptop after each one
* Check the Device Manager to see if there are anymore unknown devices

If still under warranty, click the "Get help now" icon on the right to start a live chat session.

Sorry, DELL-Chris M. No such luck.

I tried what you suggested

After that failed, I let Dell's "Detect Drivers" app tell me what drivers were missing & tried to install them. Some (that were already installed) were successful but several failed, saying "Not correct for this laptop". Then, I downloaded ALL of the drivers for the Inspiron 5748 laptop & tried to install them, one by one. Again, those that were for hardware installed in my laptop were successful & the rest were not.

Through all of this, I still have the same three "Unknown" devices.

Any other ideas?


??? so what happened here???

NONE of your chipset drivers are installed.

Intel(R) Serial IO I2C Host Controller - 9C61    is  ACPI\INT33C2\1
