Safety and Environmental Concerns 3 Safety
I will be telling you how to clean a pc that has dust inside it and around it and how to deal with heat issues as well. There are some things you need to know before working on your computer as well as equipment you need to have handy. Some things you need to have with you to keep yourself from being burned or electrocuted are ground bracelet (also known as a antistatic wrist strap), ground mats, static shielding bags (to put old components in), and antistatic gloves. These items are for your safety while working on your tower. Never forget to turn off your tower and unplug it before working on it. Cleaning

How often do you clean your computer case, inside and out? Did you realize that having a clean computer is a necessity for the system to run at its optimal levels? Having dust and dirt build up inside your computer case can restrict the airflow and cause serious damage to your components. One common example is when dust gathers on the heat sink and fan. If left there it can eventually cause the processor to overheat and shutdown the computer without warning. The main factor to consider when you clean inside your computer case is safety. You will first need to be familiar with how to open computer cases and the precautions you have to take. There are important steps to complete before starting to clean your system like removing all plugs from the computer and certain preparation to make sure you do not damage the components inside your computer case. Of course it is preferred that you have the professional tools to clean inside your computer case, however you do not always need all the fancy cleaning tools available. Everyday household items will do. Here is a list of some of the tools I use to clean my computer. * Soft paint brush: I use this when an air compressor is not available. Gently brush the dust from inside the case. Make sure you do not accidentally move any wires or connections. * Air compressor: I would choose to use this before anything. It’s quick and easy and removes dust properly. Do not go too close to the motherboard though. It will work fine from a distance. It is also best to remove the cpu fan and clean that separately. * Compressed air can: When you clean inside your computer case, this disposable compressed air can that will blow the dust out. Be sure to keep the can upright, otherwise it will leak liquid. Always read the instructions...
