Regular care and maintenance is required for your computer to run at its optimum. Static electricity can attract dirt, debris and dust which enter small hard to reach crevices of your computer and clog up your keyboard and cooling fan. Use compressed air cans which are inexpensive and do a wonderful job.
Avoid using paper towels and harsh household cleaning solutions to clean oily smudges on monitors as these can scratch the delicate surface of the monitor. Use wipes specially designed for monitors.
Adding printers, cameras, microphones etc. can contribute to cord clutter which can be dangerous. Take a few minutes to arrange all your cords. You’ll be surprised to find unnecessary cords that you dont need. Shop for wireless devices if possible.
