driver IRQL not less or equal

Hi,

I recently bought and installed Battlefield 2142 and when I go to launch it it blue screens me and gives the following error

DRIVER_IRQL_NOT_LESS_OR_EQUAL

I then have to manually restart after which windows tells me that the system has recovered from a serious error.

My spec more than covers the games requirements,

Can anyone help me diagnose and solve this problem, it's doing my nut in!!

p.s I am tech newb and would really appreciate simple answers if possible
Thanks
