Updating dell ati drivers
If you meet this error after installing driver, after rebooting, perform a clean install of AMD drivers again. Then Windows will install the Graphics drivers automatically.So far, I have only tried the driver-only package and the Avivo converter.
It is important to make sure your Dell Inspiron has up-to-date drivers, which are software files that enable the central processing unit to communicate with hardware components.
Now i was thinking maybe this will work for the graphics driver for ATI/AMD cards.
This worked to re-instill the wifi drivers now my wifi is working.
I have an Optiplex 760 with Dell's ATI Radeon HD3470 256MB, running Windows 7 Professional x64 (I also experienced this problem with the 32-bit version).
Dell's latest drivers for the card work fine (version 8.640), but anytime I try to install a newer (including the latest) version of the ATI drivers, Windows bluescreens.
After a clean install of Ubuntu 12.04 on my Dell Inspiron n5010 Laptop, I can't install the ATI drivers! Command for graphics fix was: Dell Inspirion N-5050 Ddownload two packages: dkms and bcmwl-kernel-source.
