I have an Inspiron 14r n4110 with AMD Radeon HD 6470m and Mobile Intel(R) HD graphics. Recently Windows update came out with an update for the Mobile Intel graphics. After updating it, the name changed to Intel HD Graphics 3000, but the my AMD Radeon HD 6470m graphics card showed a yellow triangle with an exclamation point and my control catalyst center disappeared . But when i revert my Intel graphics, it turns back to normal. I have searched Google for answers, tried different solutions that failed to work and experimented with drivers. An answer is highly appreciated.
I suggest you to uninstall and reinstall AMD Radeon HD 6470m graphics card driver.
Please follow the below steps to uninstall the video drivers:
Run the driver file for AMD Graphics, follow the on-screen instructions to install the driver and restart the computer when prompted.
Check the functionality of the system and post the results.

when i uninstalled the amd radeon hd 6470m driver, the option to "delete driver software for this device" did not show. the windows update was successful. but when i installed the amd radeon hd 6470m driver from the link you provided, i installed it through the custom option, but everything checked in the box seemed to already be installed. i checked the device manager, intel hd graphics 3000 was under display adapter but amd radeon hd 6470m was no where to be found.
In this case we can try updating the BIOS to the latest version. Please refer the following link to update the BIOS: http://dell.to/QjjZDAEnter the system service tag, choose the Operating system and download the latest BIOS.
Note: Few things to ensure before updating the Bios, the Ac Adapter should be plugged in and the battery should have minimum of 10% charge. No other peripherals should be connected to the computer. Please ensure that the Bios update should not be interrupted.
Check if AMD graphics card is detected after the BIOS is updated.
Please post the results.
