UnaParu,

Did you recently install/reinstall the operating system?

Rick

Yes

Actually I just bought the system few days ago

UnaParu,

If you installed Windows from the begining, then make sure to install the chipset drivers first or the rest of the drivers will fail to install. How to Download and Install Drivers in the Correct Order

Rick

chip set driver was installed by the window itself.

UnaParu,

Download and install in this order...

Intel HM75 Express Chipset Family,9.3.0.1021,A01

intel ME driver,8.1.0.1263,A01

Realtek USB 2.0 Card Reader A00 6.1.8400.30136

Then go to Dell Warranty Status enter your service tag, click on original configuration. Look for the wireless adapter you have installed. Then go to Drivers & Downloads enter your service tag, select your operating system. Under Network, download the drivers for your adapter.

Then download Dell QuickSet.
