Computer Freezes when I change gamma in Hitman2

The title pretty much says it all.

I have a Sapphire Atlantis 9600 Pro video card with the latest driver (which I believe is the latest).  My OS is Windows XP Professional SP1.  Whenever I try to adjust the gamma settings in Hitman 2 (it is too bright), my entire system freezes.  I can't ctrl-alt-delte out of it.  I have to press the button to restart my machine.

Any ideas?

hv u try to reinstall the driver or reseat the card?

verify that your computer hardware is compatible with Windows XP.

For the latest compatibility information, and to download and install drivers for the listed hardware, see the Microsoft Windows Hardware Quality Labs Web site at:

Is your system 8x speed?
here is a problem with the cards and there is no fix yet.
your driver is the latest.

Some similar problems were reported with cracked versions of different games. Is yours a cracked one or an original?
If that's the only context when you have such problems then I'd say my above statement is right. Anyway,  there are lots of thing that can generate this kind of behaviour.
AGP drivers for your motherboard, vid drivers (latest doesn't necessarily means the best), AGP aperture size  and mainly all BIOS settings that are video related.
However, I stand on my opinion.
