Did you properly uninstall the Dell drivers before installing the ATI drivers?

To ensure optimal performance of your graphics card it's recommended you uninstall the factory drivers from Dell and install the latest version of your video card drivers directly from the manufacturers website.

In this case you have an ATI Radeon 5670 on Win-7 64-bit.

Go here. support.amd.com/.../AMDSupportHub.aspx

I would recommend you watch all 4 videos at the bottom of the page and follow these instructions when downloading/uninstalling/installing drivers.

Other users can chime in but I'm pretty sure this will work when uninstalling factory dell drivers. You want to make sure you get the dell drivers completely removed from your system before installing the new ones from ATI.

If you didn't properly remove the dell drivers the first time around that's what could be giving you issues now.

But thanks for the info and I'll try again

I did properly uninstall the drivers, I used Driversweeper.\

I was having the problem when i was having the freezing up and driver errors when I was using the most recent amd driver so i called the alienware support and they told me that my computer would only properly support the dell drivers.

My problem now is that dell hasnt updated the driver for the Ati Radeon HD 5670 since April of 2010. So Neither driver has been working for me and they seem like my only options so im at a complete loss

Ugh no It didnt work. I followed the videos on the website and I was able to uninstall like the video tells you but upon rebooting after the unistallation I was confronted with a blue screen and so I had to revert to when the dell driver was still installed just to be able to startup my computer.

Is there any other safe way to unistall a my Dell video driver?

Uninstall using the directions below. then install drivers from AMD site for appropriate operating system. The link below is for W7 64 bit.

The following documents provided thorough un-install instructions for cases that may require a thorough un-install.  This document is a fairly lengthy because of the numerous screen shots provided.   In most cases a regular un-install and re-install will correct most problems; however should you wish to rule out a clean un-install the instructions have been provided below. 

Please read the entire document before proceeding,  if you are not experienced enough with these steps, please contact your system administator for assistance or seek knowledgable help.

 These steps are provided at your own risk and user discretion is advise.

Un-installing

Any pre-existing graphic drivers must be first uninstalled, to prevent any errors that may occur when installing the latest ATI Catalyst™ drivers.
Note! The following instructions only apply if a graphics driver pre-exists on the system. This step can be skipped if the system currently has no legacy graphics drivers installed.

1. Click on the “Start” button
2. Open the “Control Panel”
3. Select “Programs and Features”
4. Select “ATI Catalyst Install Manager”
5. Click on “Change”
   
   
6. Click on “Next” when prompted for the “Welcome to the InstallShield Wizard for ATI Catalyst™ Install Manager.”
   
   
7. Select "Express Uninstall All ATI Software"
8. Follow the on-screen directions and restart the system when finished
   
   
9. Note! The Windows User Account Control (UAC) will prompt for “Do you want to allow the following program from an unknown publisher to make changes to this computer?” Click on “Yes” to continue with the uninstall process
   
   
   

10. To verify that the legacy graphics driver has been uninstalled, return to the "Uninstall or Change a Program" list and ensure that there is no ATI specific software listed

11. If ATI specific software is still listed, remove any remaining ATI software components using the above process and restart the system when complete

Manual un-install

Once all of the remaining ATI entries have been removed from the Programs Un-install  list and the computer has been rebooted, the remaining registry entries, Program Files, Program Data, and AppData entries and will need to be removed.

Not all entries will be listed these locations, however this is a step to double check to see if there are any ATI folders left in the system.

To start check C: Program files (this may differ if you have labeled your main hard drive a different letter)

Windows 64 bit users will need to also check c: Program Files x86 

Look for any ATI folders or ATI Technologies and delete them.

Removing entries in the ProgramData folder

This folder is hidden by default, and if you have not shown your hidden files and folders you will not be able to view this section of your hard drive.

To show your Hidden Files and Folders complete the following:

Click on Organize followed by Folder and search options:

Click on View then select the option to Show hidden files and folders and drives.

Apply the changes and Ok.  Once enabled navigate back to C: ProgramData and remove any ATI folders.

Clearing out ATI folders from the Users folder:

 Depending on how many users you have created in the operating system you may need to double check the Appdata folder for each user for any leftover ATI folders.  In this example GCC Win7-64 bit is a user that was created when setting up our test system.  You will have your own folder names.  

Check the AppData folder followed by both Local and Roaming folders. 

Removing Registry entries manually

Click on Start, and in the Search field  type in’ regedit’ and click OK.  This will launch the Registry Editor.

• Create a back up of the registry by clicking on File, then Export.  Choose a name for the file and save it on your desktop.  You have backed up your registry.  

• Click on the (+) next to HKEY_LOCAL_MACHINE

• Click on the (+) next to Software

• Click on each folder that references ATI Technologies or ATI and press delete on the keyboard.  When prompted for confirmation, click Yes.

• Click on the (-) next to HKEY_LOCAL_MACHINE to collapse the list.

• Click on the (+) next to HKEY_CURRENT_USER.

• Click on the (+) next to Software.

• Click on each folder that references ATI Technologies or ATI and press delete on the keyboard.  When prompted for confirmation, click Yes.

• Close the Registry Editor.

The last step before re-installing the driver is it to clear the video card entry from Device manager. 

To get there select Control Panel followed by System and Security and the Device manager.

Once the Device manager is open right click on the ATI Radeon/FirePro/GL entry and un-install the driver, you will need to delete the files from the system when prompted.  

Now that you've removed the existing ATI software you're ready to install the new drivers and software, please reboot when prompted and install all files in the order specified.

Okay I have followed the uninstallation process exactly but upon system reboot my computer goes into a blue screen. I am then forced to revert my computer back to a previous state: a state where the ati programs are still installed. For some reason I cannot uninstall my driver.
