How To Restore or Reinstall Microsoft® Windows® on a Dell™ Computer

and How to by-pass the Dell Download Manager

First, don't use the Download Manager ... ever.  Since you already have, delete all your Dell "cookies" and choose to download Via Browser.

Second, just make sure you install the System Software first:

Then the Chipset:

After than you can install the following:

Ethernet:

Video (choose the actual graphics option you have ... if you are unsure, go to Device Manager (right-click My Computer, Manage), right-click on the Display device or Unknown device, Properties, Details tab, Hardware Ids from the dropdown menu, and give us the VEN and DEV ID's):
http://support.dell.com/support/downloads/driverslist.aspx?os=WW1&catid=6&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=DIM_CEL_3000&hidos=WW1&hidlang=en&TabIndex=&scanSupported=True&scanConsent=False

If you are missing anything else in Device Manager at this point, let us know what VEN/DEV ID's you are missing.
