  1. Turn off your PC

    Before you open your computer case, you should shut down and unplug your PC. When current flows through your computer, components can become very hot. Giving your computer at least 15 minutes to cool down prevents possible damage from contact with hot surfaces.

  2. Dust the interior

    Using a can of compressed air, blow the dust out of the interior of your PC. Pay special attention to heat sinks and fans, as these tend to accumulate the most dust while in use. If your case has air filters over the exterior fans, remove these according to the instructions, and clean them as well. This increases airflow through your PC and allows it to dissipate heat quickly and efficiently.

  3. Clean your peripherals

    Hold your keyboard vertically over a trash can, and use the compressed air canister to blow between the keys. This dislodges dust and crumbs inside your keyboard that might interfere with normal use. Check your mouse's optical sensor for obstructions. If you like, you can give both peripherals a quick once-over with an antibacterial wipe.

  4. Wipe down your monitor

    Use a microfiber cloth to remove any dust on your monitor screen. If it is particularly dirty, you can use a slightly moistened paper towel to remove accumulated debris, or use a surface cleaning product specifically made for LCDs. Avoid cleaners not designed for computer monitors, as they could damage the surface.
