No prob.
Actually if you talk to computer techs thats a funny subject. Many of them end up charging for 1-hour bench time for things that werent broke. People tend to leave their computers running. When something goes wrong they unplug it, clean off the embarrassing dust, and take it in to the shop. But just unplugging the machine, cleaning it, bouncing it around abit in the car, then pugging it back in is often all that is needed.
