So yeah. I installed the demo for Champions Online a couple days ago, and found that it causes a good chunk of Nvidia card user's computers to bluescreen.
While I've since found a way to avoid that happening when playing the game (putting the game in windowed mode, and shrinking that to half my screen size before going to any loading screens), It's already taken it's toll on my system, as my computer has been FAR slower then it used to be.
And it's to the point where I can't even so much as play a browser game like Realm of the Mad God, without my whole computer grinding to a halt.

So chances are I'm going to be gone for a couple days as I back up my stuff and reinstall windows and other programs again.
