Please Help Me fix this DRIVER__IRQL__NOT__LESS__OR__EQUAL

I got this styleshot digital camera and I installed the programs on the disc it came with..it told me to restart and I did..when restarting I get up to my wallpaper and icons appear then the blue screen that says DRIVER__IRQL__NOT__LESS__OR__EQUAL.....WELL...my husband took over and went into safe mode and restored to two days before, sad to say it still happens with the blue screen and the blue screen message: DRIVER__IRQL__NOT__LESS__OR__EQUAL

How do I fix this?

HELP please Bump

 

Hi. Not sure how much help this will be, but I have had the same blue screen of death error several times relating to wlan111t.sys, a driver for my Wireless USB Network adapter. When googling it a few weeks ago I found others had had the same issue but found no suggested cause or solution.

If you google "DRIVER IRQL NOT LESS OR EQUAL" you will find lots of forum posts about this error occurring for various different drivers, but from what i've briefly read, it can be caused by either conflicts between programs, or faulty RAM - check out http://www.pcadvisor.co.uk/forums/index.cfm?action=showthread&threadid=318886&forumid=23 and http://www.memtest.org/ to rule out the RAM possibility
