IRQL_NOT_LESS_OR_EQUAL during run of Adobe CS 4 product

"The two main causes is usually either faulty memory (1) or bad drivers(2).

(1) I recommend you run Memtest86+, which should show if you have any bad memory in your system.

(2) If you have a lot of badly coded drivers installed on your system - especially if you buy a lot of USB tat, it is possible that the drivers corrupt other items on your system. Uninstall things that you no longer need, but it is always hard to advise on this without seeing the actual system. I still advise you do (1) first.

Lastly, Try running Bluescreenview, and see if it shows you the name of the faulting module (usually the third or so line up from the bottom of the BSOD screen). The thing is, whilst IRQL_NOT_LESS_OR_EQUAL shows a problem, just saying that does not easily tell us what the problem is with."
