hi

i just returned to the game and i have a small problem.

Every now and then the game freezes; just locks up and no mouse movement and the screen is frozen and no sound.
It can be after 10 minutes or up to 6 hours.
Sometimes it will do it twice in a row.

I am running a gigabyte mb with an intel 9650 and 4 gig of ram,
windows xp sp3,
nvidia 9800 gtx2 video card,
the onboard sound,
1100 watt ps,
all drivers are up to date.

Everything is well cooled and every other game and program works fine.

Any ideas would be well appreciated.

Thanks
