There is an order of installation of drivers that must be followed when you do a manual install.  The two critical pieces are the Dell notebook system software and the Intel chipset driver -- without these, many other drivers -- including the ATI Catalyst drivers - will not work properly.

See step 4, here

i have the same problem can any one help us

my 3450 had AMD drivers and I also could not use the automated installer so I downloaded and installed the drivers manually by picking Radeon HD Series and Windows 7 x64. Driver is now version 12.8 and everything is as it should be.

Hi there, iam just wondering how did you order a 15R 5520 with switchable graphics because iam trying to do so but it doesnt show in my configuration page :/

Dude I got exactly the same problem in my inspiron n5520, in fact when I start dell support center and view the system cofiguration it does'nt detect any amd hd 7670m card and shows only the intel hd 4000 card... although i can see it in the device manager. And playing games is like self torture as it doesnt switch to hd7670 and plays on intel hd 4000 even in the high performance mode...dell seriously needs to look into, this lots of people are having this issue.

me too having the same problem....I have an inspiron 4050 running on a Ati card and same thing is happening to my laptop tooo....its just getting into my nerves and iam wondering whether it has a graphics card or not????????

i am having exactly the same problem if anyone finds any solution please do let me know @ <ADMIN NOTE: Email id removed per privacy policy>

p.s. I found about 5-6 questions expressing the same problem and when i tried to post these post they said"duplicated posts" !!!! well DELL find us a duplicated solutions then!!

Hi everyone,

Try the following driver and check if it fixes the problem :

leshcatlabs.net/.../leshcats-catalyst-13-1-whql-unifl-v2-1-for-amdintel-laptops

Note that you have to clean install this driver i.e. you have to uninstall the old driver from the system and then reboot and install the above driver and then reboot the computer again. The above drivers have a good success rate and have been reported as solving the issues with switchable graphics.

Hope this helps

yes it works great but u have to uninstall the drivers and catalyst first my games work very smooth now .... :D 

try  it you will not be disappointed by this ...
