Driver_irql_not_less_or_equal

Hey peeps, im looking for a little help regarding my BSOD problem. A brief overview of the problem, - whilst playing World of Warcraft online, every so often im gettin a BSOD with the DRIVER_IRQL_NOT_LESS_OR_EQUAL error , with OXOOOOOOOD1 ( OXOOOOOOO4, OXOOOOOOO2, OXOOOOOOO1, OX89269340 ). Sometimes my game runs for an hour or so, sometimes maybe a few minutes. I have done a little research into it & have tried updating my drivers, which didnt help.

I read that i should get HiJackthis and post the results of the scan, which i have posted below. I am not technically minded in such matters and am worried if i try fixing this without expert help i may make my PC woes worse than they are now.

I appreciate its boxing day and late in the day, but any help / advice would be greatly appreciatted.

Thanks in advance

An Unhappy Chappy
