Windows 7: Random BSOD "Driver_IRQL_Not_Less_Or_Equal"

03 May 2013   #1

Windows 7 Ultimate x64
Random BSOD "Driver_IRQL_Not_Less_Or_Equal"

My PC:
OS - Windows 7 Ultimate
Case - Rosewill CHALLENGER Black Gaming ATX
CPU - AMD Phenom II 965 Black Edition 3.4Ghz
RAM - G-Skill Ripjaw Series 4GB DDR3 1600 x4 (16GB)
HDD - Seagate Barracuda 7200 1.5TB
GPU - XFX Radeon HD 4850
Display - ASUS MS238 23'' LED (Primary)
Display - VIZIO E-Series 60” Razor LED™ E601i-A3 (Secondary)

1st off my build is now 2 years old (built Feb 2011)

I used to have a serious blue screen issue when I 1st built my PC and it took forever to figure out what was causing it, basically I had my ram speed set to high. I have no had any persistent issues since Feb - May of 2011. Now recently I have been noticing more and more frequent BSoD's, but only when I am actually using my PC, it is on 24/7 and I have program/games running all the time and I never wake up to a PC that has rebooted. Also I have no idea if this has anything to do with it or its just a fluke but the last 3 BS's have happened while browsing the internet (Firefox) two of which happened the exact moment I opened a new tab. I get the message Driver_IRQL_NOT_LESS_OR_EQUAL, do not know much more but my .dmp files should tell a trained eye whats wrong!
(I also plan on getting a new video card very soon as I know my current card is horrible underpowered and I feel it may be going bad.)
