How to enable Direct Draw Acceleration ?

[justsum1uknow]

So I recently bought a new graphics card (moved from nVidia to AMD) I forgot to uninstall the old drivers after replacing the graphics card, I uninstalled them about an hour ago and now I can't play most games like ArmA II, I googled the error and I had to enable Direct Draw Acceleration which says unavailable in my dxdiag display tab.
I have the latest drivers and I have installed DirectX.
Some sites like Microsoft said that I need to accelerate my graphics by following these steps

To turn on graphics acceleration
a. Open Display Settings by clicking the Start button, click on Control Panel
b. Click on Appearance and Personalization and click Personalization
c. Now click Display Settings.
d. Click Display Settings, and then click Advanced Settings.
e. Click the Troubleshoot tab, and then click Change Settings.
f. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
g. Move the Hardware Acceleration slider to Full.


The Change Settings tab isn't available for me.

Sounds like the drivers have not installed correctly, DD usually activates automatically.
Go to Add/Remove programs and check the Nvidia drivers have been uninstalled.
Uninstall any tweaking/tuning software (Afterburner, EVGA Precision, Speedfan etc ) deleting any saved profiles when requested.
Restart.

If no change:
Set a Restore Point.
Download and install DriverFusion.
Download and save, do not install, the latest WHQL drivers directly from the AMD site and only from there.
Uninstall the current drivers.
Reboot into Safe Mode and run DriverFusion from there, once it's finished, reboot normally.
Install the saved drivers.
Restart.
