Clean Dust From Your CPU

If you have a problem with dust in your house, it's worth it to blow the dust from your computer. You have to unscrew and remove your CPU casing (make sure the power is OFF first) and then use the blower to clear any dust inside the PC. The purpose here, other than for cleaning and regular maintenance, is to prevent spending a whole load of cash at your PC engineer's workshop.

You can actually save time and dough doing this, if it's only to prevent your computer heating up and restarting it many times.
