Why and how to clean your computer
6:12:00 PM Dust clogs the vents behind your computer, which causes your CPU to heat up—and heat is the biggest cause of component failure in computers. Regular cleaning could save you costly maintenance fees down the road.
Sometimes your computer fails to start up when you need it most.
It doesn’t boot, show blue screen “error detected” or does not display anything on the monitor. This happens usually when the PC remains uncleaned and out of service for a long time.The best thing to do is to to the cleaning your self, is cheaper and safer.
To begin the cleaning procedure you will need :
A No.2 Philips cross-head screwdriver
A small flat-bladed screwdriver.
One can of compressed air
One small paintbrush with long natural bristles
A flashlight
A Vacuum cleaner with a hose and nozzle
DO NOT OPEN CASE BEFORE YOU UNPLUG THE POWER CABLE FORM OUTLET
CPU fan and heatsink
This is the most important part of the cooling system - dirt collects on the fan blades and clogs the heatsink vanes. Use the paintbrush to brush the dirt off each blade and off the heatsink vanes if accessible. Using the pencil to hold the fan blades still, blow out the fan and the heatsink with the compressed air. It is important not to let the CPU fan (or other fans) spin up under the air blast as damaging voltages can be generated through a dynamo effect. Expect significant dirt to be ejected from the CPU heatsink. If you want to be particularly thorough moisten a Cotton-tip with glass cleaning fluid and wipe down the upper and lower surface of each fan blade
If your computer makes a grinding noise as it powers up or shuts down, it can serve as a good indicator that you're well overdue for power supply maintenance.
Your PC's power supply is one of the most vital components on your machine. The power supply, as its name implies, feeds electrical current into your PC, allowing it to operate. A poorly functioning power supply will cause your entire computer to shut down. Regular power supply cleaning is important to ensuring a long power supply lifespan. Generally speaking, you should clean your power supply at least every 3 months.
Cleaning the power supply it`s easy ,using just compressed air you should be able to clean 90% with out the need to open it up.
The video card fan is also have another fan on their video card. If you do have a fan on your video card, stop the fan with something and spray it until its clean as you did with the other fans.
Ram-Take the RAM out and clean it’s contact edges with a brush. Also dust away the RAM socket in your motherboard. Dirt can sometimes build up in ‘drifts’ around the memory sticks and the video, sound or modem card slots. If possible use the compressed air to blow it out, avoid to use the brush here. Place it again tightly.
To finish up, I give the whole case a spray with the air which includes the motherboard, RAM, cables and the bottom of the case to blow away any dust it already had and dust that had fallen while we were cleaning the other parts.
