This is not a dell issue.

Support options based on the model of your machine (desktop, laptop, OptiPlex, Dimension, Latitude, etc) in order for your call to be routed to the appropriate technician.

You will need:

3. The Service Tag and/or the Express Service Code for your computer-

* The Service Tag can be found on the back or bottom of your computer as a bar code label

* The Service Tag and/or Express Service code may also be found from the Start Menu---> Programs ---> Dell Accessories --->Express Service Code
