It’s important to maintain the software on your PC by performing regular checks and scans to resolve any problems which may occur and also to stop any glitches from happening in the first place. Disk cleanup, defrag the hard drive, spyware and adware removal, virus scans and Windows registry checks are all imperative to having a computer running at its optimal performance levels.
What happens if you perform these activities on a regular basis and still find your PC running slowly or crashing? The most probable reason for this and one overlooked by many people is a dirty computer. The build up of dust that gathers around the CPU unit, the processor, the power supply and the ventilation area can seriously inhibit the performance of your PC.
Not only is dust and dirt a menace but cigarette smoke, pet hair and various other substances can all contribute to the performance issues you may be experiencing with your computer. It’s just as essential to have a regular hardware cleaning schedule as it is to have a software clean up.
Before you start cleaning your PC it is important to use the correct tools and know how to carry out the work safely, avoiding damage to the components of your computer. Below is a list of what you will need:
-
Screwdrivers of various sizes
-
Cotton cloth
-
Glass Cleaner
-
Anti static wristbands
-
Rubbing Alcohol
-
Tweezers
-
Compressed Air
-
Lint free cloth or rag
The following steps should be used as a guide to cleaning your PC:
-
Read the owners manual. This will provide the correct instructions on how to clean your computer. Check to see if it gives any helpful tips.
-
Switch off the computer and disconnect power supplies for safety reasons.
-
Remove the CPU casing. You will need to use the screwdrivers to do this. Carefully remove the screws which hold the cover to the casing. Inside are the motherboard and other important hardware. There will most likely be a large amount of dust and dirt gathered here.
-
Clean the CPU. Use the can of compressed air to blast away any dust which has accumulated on and around the motherboard. It may be necessary to remove any cards installed to give the area a thorough clean. Don’t forget about the slots in the motherboard.
-
Clean any grime from the fan. Blast the compressed air into the PCs fan dislodging any debris found there. Check around the heat sink too for any additional grime.
Don’t forget to clean other exterior parts of your computer as well. This will keep it fresh and looking like new. Wipe your monitor regularly as the static generated by the power supply will attract a lot of dust. Use glass cleaner and a lint free cloth or rag to wipe the monitor in a circular motion.
It’s important to place your PC in an area which is well ventilated. Keep it away from direct sunlight and never expose it to dangerous pollutants such as smoke. Carry out a regular cleaning schedule – every three to four months should be sufficient to ensure a spotless and well maintained computer.
