On your troubled machine set up a terminal and ping google.com repeatedly once a second. Watch to see if that actually stops when your machine is showing problems.
You don't have to shell in from a separate machine. I just find it more repeatable and if the machine really hangs sometimes you can regain control without resorting to magic keys.
