This is a long time issue with ATI cards, try checking the ATI forums. If
you have a system restore point available before the problem started, use
it. Otherwise try completely uninstalling the video drivers and restarting
your system so that it comes up in VGA mode. Reinstall the ATI video
drivers and restart. That will work some of the time, the rest of the time
if you don't have a system restore point you have to reinstall Windows
(repair mode).

Im experiencing the same problem after my dad says that he reinstalled Windows XP on my computer after it got a virus. The Accelerators are all unavailable and i cannot access any type of game that requires them. Is there a simple way to enable these Accelerations? Before my dad reinstalled Windows XP the games worked fine and I cannot understand how a simple reinstallment would disable all of those. Can you please tell me how to reactivate them as easily as possible.

see i understand ur prob.
wat u hav 2 to is tat
first right click on ur desktop goto properties
then go to settings bar & click on the option "advanced"
now goto troubleshoot bar & full the hardware accleration.

you dad probably hasn't installed the display card drivers.

you need either the crap integrated ones that come on the mobo disc, or, if you have a dedicated card of NVIDIA or ATI make, you need to install the relevant ones.

until then, you'll have no 3D acceleration and therefore not be able to play games that need it.
