Cleaning you computer hardware

Computers, as appose to other electric or electronic devices, are not maintenance free. Quite the reverse, it occasionally needs hardware cleaning. This will not only give your computer top performance, but will also prevent many unforeseen computer breakdowns,

The obvious reason is, after we use the computer for 6 – 12 months depending on the environment, it will have a layer of dust sitting on it. This happens even when we position our computer in a clean room. The computer parts in my own house always collect a fair amount of dust.

It would, therefore, be advisable to give your computer a clean up twice a year or so. But before we do it, we must do some preparation. First, get a piece of paper, a pen, screw driver, brush and a small can of spray that clean the metal parts of the electronic circuit.

When we are ready, unplug the computer completely and take only the case out to a well ventilated area. Open the case and take note of what you will be doing below (This is important to help you put it back correctly).

1. Unplug all the devices from the mains supply. These include hard disk, floppy disk, DVD Rom, CPU fan, and the main power supply plug from the main board.

2. Take the main board battery off.

3. Unscrew all the attached cards like Monitor, LAN, Modem, USB, Sound, CCTV, if there is any (the newer main mother board now has most of these collectively assembled on the main board) and pull them out carefully.

4. Use the brush to dust off all the computer parts.

5. Erase the bronze color stripe part of the cards. Rub them hard until they shine.

6. Spray clean the main board, IC or chip spikes, and the needle like metal parts of the hard disk, floppy disk and DVD ROM.

7. Spray also all the metal parts that protrude out from the main board at the back of the computer case. (Do not wipe with paper or cloth if you over spray as it may cause damage to it. Just let it dry ).

8. Put back all the cards and screw tight.

9. Plug back all power supply lines.

10. Insert back main board battery.

11. Close the case and take to join back to the monitor, keyboard and mouse.

Few words of caution:

1. Please make sure you write down the details when you unplug or unscrew things. You will need them when you put things back.

2. Do it gently and patiently. Do not force your way through in anyof the steps.

3. You know how to reset your CMOS-BIOS after you put back the main board battery. (You may bypass steps 2 & 10 if you do not. But be careful not to spray right on the battery to prevent short circuit)

This will restore your computer hardware back to its original new look when you first bought it. Performance will drastically improve also comparing it to before the cleaning was done. It will enhance further with some adjustment to the software.
