Problems with directx games

[Niclas]

I have a problem with Unreal Tournament 2003 and C&C:
Renegade on my new computer. In UT2003 everything works
and the games starts OK. But if I try to change the
resolution it just hangs - sometimes it goes back to the
initial resolution (640x480). Starting the game in Safe
mode it still works but I still can't change resolution.
Likewise C&C: Renegade. It will not start, but when I
changed the setup to having it start in a window on
desktop it worked flawless.
I have updated my Windows XP Home SP1a with all necessary
pathes - likewise the motherboard (ASUS A7N8X), the
graphiccard (ASUS 9820 - i.e. nVidia 4200) and the games
have the newest pathes also.
Games like Quake3 and Seroius Sam functions without
problems at all. It seems like a directx error or what?
Any suggestions?

Install DirectX 9 and then upgrade the video drivers (52.xx) and the
motherbaord chipset drivers.
