PC question
 

When you have a pc on but you're not even using it because you mostly use your mac, and it starts to make a sound as if the hard drive is laying a big long fart, as if it's grinding the clutch in there or something... wtf is it doing?

I've never had a hard drive lay a big long fart.

Crashing, like the head contacting the platter :Oh crap

might be a fan

my first thought too
