I Nintendo-ed my video card

I just bought a new video game for Bridget, but every time it would start, the computer would lock up during the intro video. I messed around, trying to figure out if this was a problem with the processor possibly overheating, whether the video card was acting up, or the motherboard was dying. I ran some diagnostic tests, but that showed me almost nothing.

So, finally, I took out the video card and blew on the fan, releasing the months of dust stored inside.

Ta-da! Working video game.
