Can't Adjust Hardware Acceleration! Help!!

Hi, i am new to the forums and i am not sure if this under the right category but i upgraded from Windows XP to Windows 7 Ultimate and i cannot adjust Hardware acceleration on my PC. When i go to the Trouble shoot tab "Hardware Acceleration" is greyed out. Is there any way to manually disable or "Lower" hardware acceleration through Rededit? Any help will be appreciated. Also i need to disable this for programs that lag.

I'm not even sure where you are, to be honest, but why are you wanting to disable hardware acceleration?

I said that above! When hardware acceleration is on some programs lag.

If the setting is greyed out your video card will not allow you to make that setting change.

Is there anyway to do it manually? When i tried it in Safe mode it said "No Registry Key Was Found" Is there a way to add this command to the registry?
