I don’t know why but for some reason this makes me think of one guy like 18 years ago who sprayed the motherboard of his Compaq desktop with WD-40 because “it was runnin’ slow” and then brought it to me when that didn’t fix it.

I gave the motherboard a nice bath in electronics cleaner and replaced the hard drive (which was the actual problem). That PC definitely had a ‘nice’ smell afterwards.
