Hi gilbertooo,
Did you try installing the driver from the link above?
If you are not able to install the driver on your computer, you may download the set up file > right click and run as administrator > Extract the driver and make a note of the path where the drivers are extracted.
Usually the drivers are extracted to C:Dell/drivers/
Navigate to the folder where the driver is extracted and then right click the set up file. Select 'Run as an Administrator' and see if it works.
In case you are trying to re-install operating system, ensure to back up all the data from computer as this step leads to complete data loss. For detailed steps on operating system re-installation, you may refer to link: http://dell.to/ZDfMyt
Once the operating system is re-installed, you may download and install the drivers on your computer. You may download the drivers from the link: http://dell.to/10ksYYf
To know more about the installation of drivers in correct order, you may refer to link:http://dell.to/12oPjsc
Hope this helps.
