BSOD When Browsing, PAGE_FAULT_IN_NONPAGED_AREA

My computer's been perfectly stable for months now and suddenly it BSODs again. (the previous issues had been entirely accounted for and rectified) I have my hunches but I need someone to take a look at the BSOD logs to find out what exactly caused this one.I've been doing just fine until I started playing Battlefield 3. My NVIDIA 280.26 drivers weren't good enough, the game told me so and froze every 5 minutes of play, necessitating killing the process through the task manager. I did a clean reinstall complete with driver sweeper of the 285.62 driver version and that fixed my issue. The game requires you to have all sorts of crap running in the background when you play. Punkbuster is normal but now EA has their own version of Steam, 'Origin', which needs to be playing while you run it. It also runs the game through the web browser, which required their own addon through my Firefox browser (v9.0.1).

Things were going well till a couple of days ago. I had just finished up a game of BF3 and was browsing through the game's web site when my screen went black. Everything came back up and my PC told me my video drivers had crashed and recovered. Firefox had oddly crashed as well. Fast forward to today, I'd finished playing BF3, at least an hour had passed. I was browsing some unrelated web site when my computer popped the blue screen linked in attachments. No warning at all, just browsing the net. My computer has been 100% stable up until now so I'm thinking it's either the new drivers or the funny plugin the game shoved into my Firefox.Whenever I've gone to their web site the browser opens 3 'plugin container' processes which won't close until I shut down the browser entirely. I know Origin wasn't running this last time but I might not have shut down the browser and restarted.I use Windows 7 64 bit retail on a self-built computer.I just built the system at the end of last year. 285.62-desktop-Windows 7-winvista-64bit-english-whql (installed)
