i also have 2 base system device with yellow exclamation "base system device" both code 28

but i urgently need the broadcom wireless to work..
thanks in advance.

 

and i have other questions,,this is my uncle's pc..ad since this pc was a mess..it may got virus,etc...
now the pc came with 2 disk for reinstallation,media direct and the OS
-media direct only format the HD right and make a partition if you want..
-now the OS disk install a fresh clean copy..then why it didn't install correctly those drivers..

now..in this scenario shouldn't be advisable to first wipe offf the hard drive first with something like dban or [email protected] get rid of everything and then install a fresh copy of the OS/

 

you may have to download the drivers from Dells web site

You will need at least the following.

Chipset drivers
lan Drivers
Video Drivers
Wireless drivers

Dell usually ships a 3rd CD with drivers.

use the Service tag number on the bottom of the laptop and it will get you the specific drivers for your laptop
