If you haven't installed anything recently, try removing any extraneous hardware. Remove your video card if you have onboard. Same with a sound card. Try reseating your memory, dust out the innards of your computer.I know these are broad attempts at solving this problem, but it's an obscure one to begin with. I looked up that error code, and it's giving me everything under the sun. Sorry I can't be more helpful.

Worse comes to worst, boot up an Ubuntu Live CD, back up all of your data, and reinstall. If you have to resort to this, you can at least save some time with Ninite, which installs all of you most used apps in one simple installer. It was on Lifehacker a few days ago.

It really could be that a good driver turned sour. Corruption isn't unlikely.
