Can't get AGP ATI RAdeon HD 2400 PRO video card working. Driver Is

I hope someone can kindly help on this matter.
I am trying to install an AGP ATI RAdeon HD 2400 PRO video card on my
computer but can't get it to work. This is the issue:
It seems more a driver issue (I have now an ATI radeon 9600 card installed
(128MB) and the PC worksfine. I just want some more options).
Anyway, this is the message I got today:
atiok3x2.dll - PageFault in non paged area.
STOP 0x00000050, 0xE3FA42AD, 0x00000000, 0xBF15EB8B, 0x00000001
atiok3x2.dll - Address BF15EB8B base at BF15EB8B DateStamp 4844B4B8

This happen right after I have installed the card driver. I do ha an ASUS MB
with 1 GB RAM, Pentium IV 2.8GHz and Windows XP Home edition. For this issue
I have contacted ASUS and got the latest chipsets driver and BIOS installed.
I have also contacted AMD for ATI cards driver and istalled the latest driver
"9-2_xp32_dd_ccc_wdm_enu_75974", which does not work, included also one hot
fix they provided "9-1agp-hotfix_xp32_dd_ccc_74242". Can't get the card to
work. I do believe I have done the most I could.
Does anyone knows if there is anything I can do more may be from a WIndows
XP standpoint to help my issue?
The PC is now working with my ATI Radeon 9600 and latest ATI driver 9.2. On
the card package there is nothing mentioning to limitation inusing the card,
so I assume my pC configuration is OK. By the way I had previoulsy an ATI
Rdeon HD 1650 512MB installed that worked fine (it than broke, that is why I
had to by a new card). Thanks for your support. I appreciate.
