Does your PC hang very often? Or does it seem to stall, or takes longer to process a request. One of the reasons that this happens (apart from inadequate software or hardware configuration) is that your system must be heating up. It is very important that your PC has adequate ventilation because with faster processors serving you today, your system is getting hotter than it did a couple of years ago. A cool air-conditioned room is most recommended but not always possible. So if you feel that your system is getting heated up then try to get hold of a table fan or cooler and direct it towards the PC.
