Game crashes to desktop without any error message:
--------------------------------------------------

This most likely is caused by our CD copy protection scheme. Please 
contact Infogrames technical support for help.



Game crashes a lot with different error messages:
-------------------------------------------------

The game is certainly not bug free but if you experience a lot of 
crashes in different parts of the game you might want to check out 
memtest86 to ensure that the crashes are not caused by bad memory.

Random freezes/ hangs/ bluescreens/ reboots:
--------------------------------------------

The below link leads to an awesome article going into great detail 
explaining the problematic. Please check it out :)

If you are overclocking any of your system components please revert 
to the default clock rate even though other games and 3DMark might 
run fine with your timings. Overclocking is a very common cause of 
hangs/ freezes.

Please ensure that your GPU and CPU are not overheating. Having a 
lot of fans sometimes isn't enough to guarantee a good air flow 
inside the case as something could be blocking the air flow inside 
your case causing your GPU or CPU to overheat and therefore lock 
the system. Keep in mind that heat builds up very quickly. A lot of 
customers have found that either ensuring proper cooling or 
underclocking their cards have resulted in a more stable gaming 
experience.

You should use the default "Software 3D Audio" for sound output and
you could also try playing without sound (-nosound on the command 
line) to eliminate sound as the source of your problems.

If you have a lot of system components in your machine you might 
want to ensure that your power supply can handle your system. This 
has helped a couple of our customers.

Sometimes installing graphic card drivers over older versions 
causes problems so you might want to try using a tool like Detonator 
Destroyer for NVIDIA drivers to uninstall your existing drivers before 
upgrading to the 40.72 drivers.

A lot of customers reported the 40.72 NVIDIA's drivers help with 
random lock ups so you might want to give those a try.

A lot of Radeon 9700 customers reported that their problems went away
with the latest drivers found at the below URL so you might want to
try those.

As an alternative to the D3D renderer you could try using the OpenGL
renderer as it might offer increased stability at a slight decrease 
in performance and visual quality (no character shadows). To switch 
from using the D3D renderer to using the OpenGL renderer please 
change the following lines in your UT2003.ini from

[Engine.Engine]
RenderDevice=D3DDrv.D3DRenderDevice
;RenderDevice=Engine.NullRenderDevice
;RenderDevice=OpenGLDrv.OpenGLRenderDevice

to

[Engine.Engine]
;RenderDevice=D3DDrv.D3DRenderDevice
;RenderDevice=Engine.NullRenderDevice
RenderDevice=OpenGLDrv.OpenGLRenderDevice

At least one customer was able to resolve random lockups by setting 
NoDynamicLighting to true in his UT2003.ini file. It seems to just 
shadow the issue but hey, better than locking up ;)

VIA chipsets in combination with NVIDIA cards and AMD CPUs seem to 
be a constant source of trouble. Below are some helpful links:

If you have an Q-Fan control setting in your BIOS you could try
disabling it and see whether this helps.

You could also try turning off write combing in Windows XP in the
Display Properties -> Advanced -> Troubleshooting tab.

If you are running Windows 2000 on an AMD CPU you want to apply 
the fix found at the below website.
