Can't download Video drivers from Dell  

After a clean install of Windows 7 i needed to install drivers for my graphics, the CD i got with my laptop won't install the Drivers and when I try and download them from Dell's driver site it will download around 5-10% before it suddenly stops and says its done. I've tried doing this on two other computers I own, in different browsers and they all do the same thing. The download size on the site says 155MB but the file size is only 46MB.

When i try and open the Driver that is downloaded it comes up saying:
"This self-extracting zip file is part of a multidisk zip file. Please insert the last disk of the set"

(I did try my Driver disk, but nothing happened)

I keep clicking OK, and it comes up with:
"An error occured while unzipping. One or more files were not succesfully unzipped. The error code is 110"

I tried a Google search for the error code but not of them talk about the Drivers or a zip file. I'm at a loss... :) Please help? I'm sick of having my res set low because it wont go any higher.
(I wasn't 100% about putting this here or in another section, sorry if I got it wrong)
