Hello nihar b,

I am from Dell Social Media and Community.

After a re-installation of the operating system, you need to install all the drivers in a specific order so that there is no issues with the drivers.

Please follow the link below and the steps to resolve the issue.

Log on to http://www.support.dell.com > Click on Drivers and Downloads > Enter your service tag or click on Choose from a list of all Dell products and select your system type > Once the drivers page download all the required drivers for your system.

Once downloaded follow the link below to know the correct order to install drivers.

Note: Rename the drivers at the time of download so that you know which ones to install first and so on.
