Call of Duty4: Modern Warfare

[RedGunner]

I get this message,

The game crashes at launch with "DirectX(R) encountered an unrecoverable error"

I have tried the original and the crack and I get this :\

I have formatted my pc and its the same problem!

I have
WindowsXP Home
AMD Athlon 2600
1536mb Ram
DirectX 9.0c (latest from site)
ATI Radeon X1650 Series 512mb AGP

When I run dxdiag and I goto Direct3D Acceleration test it says it failed to create the 3d device (generic failure) Ive been googling and notice COD2 has had this problem too! I've tried putting the performance of my soundcard and acceleration down to basic, still nothing!

Im really stuck and I bought this game and I cant play it :\
