This may not be the right place for this post, but none of the categories seem appropriate, and the problem could be related to overheating, so here goes... About a week ago I started to notice this strange odor coming from my computer. It's not a burning smell or anything like melting plastic. It reminds me of car exhaust and factory pollution, like a big city on a bad day. It's been getting worse, and I don't know what's causing it or how to stop it. Does anyone have a possible explanation or recommendation to offer?
