I found this fix for my problem. It was disabled in the registry. I had tried all the normal fixes updating drivers repairing XP even installing net meeting as the Microsoft fix listed and none worked until I found this post. Hats off to this person that found the registry entry. Just passing good information on I can't take the credit for this fix. Hope this helps someone else. Be careful in the registry if you don't know what your doing.

Having problems with DirectX?
No options to enable DirectDraw within DxDiag?
Installed all the latest drivers?
Still not working?
This worked for me ...

The problem 'may' be due to DirectDraw acceleration being disabled. In
my case this probably occured when a remote desktop package was
installed.

To check if it has been disabled, look in the registry for ...
HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\DCI
Timeout=0

If it is, try setting Timeout to 7 and then switch graphics modes (or
reboot).
This will enable DirectDraw acceleration.

(Only edit the registry if you know what you are doing)

If you use Windows 2000 or XP

  • Rightclick the Windows desktop and choose Properties from the popup menu
  • Click the Settings tab and then click Advanced
  • In the next dialog box, click the Troubleshoot tab
  • Under Hardware acceleration, move the slider one notch to the left.
  • Click OK as many times as needed to return to the Desktop.

If you use Windows Vista
  • Rightclick the Windows desktop and choose Personalize.
  • Click "Display Settings".
  • In the Display Settings dialog box, click "Advanced Settings..."
  • On the resulting dialog box, click the "Troubleshoot" tab.
  • Click "Change Settings"
  • You'll probably see a User Account Control message box asking for permission to continue. Click "Continue"
  • On the resulting Display Adapter Troubleshooter dialog box, move the slider one notch to the left.
  • Click OK as many times as needed/close any windows that opened along the way, and return to the Windows desktop.

After changing acceleration, re-test After setting the acceleration back, repeat whatever whatever caused the problem in the first place to see if it's now fixed.

You can either reduce the acceleration a notch at a time until the problem goes away, or move it all the way to the left, test, then if that cures it, try moving it to the right again until the problem recurs, then back off one notch.

If changing the video hardware acceleration solves the problem, it's a signal that your computer's video driver isn't quite perfect. Check with the manufacturer (of the video system or the computer) to see if updated drivers are available. Even if your PC is brand-new, it's probably been several weeks or months since it was built and video drivers change almost daily.

Direct 3D Driver Installation Or Reinstallation?


The HAL error is because you haven't installed your grafikcard so windows is using a defaultdriver. You need to download the drivers for your videocard.

I can't say what card you have, for that you have to read the productpaper that came with the computer or open the pc and check the card.

Most graficcards have either nVidia or ATI chips. Intel is the brand on your CPU (and some other stuff) but they dont do their own graficcards.

My advice:
¤ Check the manual/documentary of the computer and look for the type of card you have for your grafics.
¤ If you can't find it in any documentation. Open the computercase and check the cards for any card with a logo from either nVidia or ATI.
¤ When you find the correct card. Check for the name of the card. (could be ATI HD5670, or anything like that)

When you have all info on what card you have. Go to either nVIdia or ATI driverpage and select your card and download/install the driver.

Restart computer hand it should be fine.


Btw. at http://free.grisoft.com you can download a free version of AVG Antivirus. So you don't need to worry about staying connected.

Cheers and hope this will help.
