How to clean your computer safely, inside and out.



By Mitz
How often do you clean inside your computer case? Did you realize that this is a necessity for the computer to run at its optimal levels? Having dust and dirt build up inside your computer can restrict the airflow and cause serious damage to your components. One common example is when dust gathers on the heatsink 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 cleaning inside a computer is safety. If you are not familiar
with opening a computer case and the precautions you have to take, please read Computer case How to open a computer case safely first. There are important steps to complete before starting to clean your system like removing all plugs from the computer.

Acceptable Tools to use
You don't 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.

Cleaning Inside your 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. Its 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: This is a 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 on the can. (Pictured left.)
Vacuum: Some people use this to suck the dust from inside their computer case, however a normal household one will not do. It is best to use a battery operated, handheld vacuum specifically designed for this purpose. Household vacuums cause static electricity which can damage your computer components.
Dust Mask: This is great for those really dusty old computers. I don't think it would be very healthy to breathe it all in.

Cleaning the exterior and components
Water:
Use water sparingly. It should only be used to slightly dampen your cloth. You do not want water dripping all over your computer.
Rubbing alcohol: I always choose to use this before water as it evaporates fast. It is also great for cleaning dirt and oily marks from the case, mouse and keyboard.
Cloth: (lint free) You should use a cloth to clean the exterior of the case, the mouse, cords, and keyboard. Only slightly damp. Fold your cloth over a few times to get in between the keys on the keyboard.
Vacuum: You can use a vacuum cleaner to extract dust and food crumbs from your keyboard.
Toothbrush: Also great to clean in between the keys of the keyboard.
Cotton Wool or Swabs: Also good for reaching those hard to reach places.
Car dash oil: This is great for blending in scratches on monitors and sometimes cases, like a Dell GX270 desktop. Don't use too much, as you do not want it dripping into the monitor air vents.
Eucalyptus oil: I use this to remove permanent pen from monitors or cases. Just put some on a cloth and rub on the writing and it will start to dissolve.

Cleaning your computer regularly can prolong its working life. We could all do with less computer troubles and this is an easy task for most people. Removing things like dust, smoke residue, dirt, or pet hair can leave your system to breathe freely.

Computer Maintenance Checklist

By Ramona Creel


BACKING UP

  • back up any documents you create on an external drive
  • disk, zip, jazz, tape, or CD-Rom are all acceptable
  • keep back-up copies of all computer programs in case you have to re-install
  • backing up your entire system at one time takes care of both concerns
  • back up as often as you regularly make changes to your documents
  • put your software drivers and your operating system disks in a safe place.

FIREWALLS ARE KEY

  • programs that keep others from accessing your computer from the outside
  • acts as a "locked gate" for your computer hard drive
  • can be installed on your computer via software (Black Ice, Norton, etc.)
  • may also come with your operating system, router, or other networking hardware


KEEPING YOUR COMPUTER HEALTHY

  • install a good anti-virus software program (Norton, VirusScan, etc.)
  • this program will scan your files, drives, and email for viruses
  • set up to scan external disks automatically when inserted into your machine
  • set up to scan your hard drive automatically when you start your machine
  • set up to scan email automatically when you send and receive
  • be sure to update your software regularly for virus updates
  • most programs give automatic prompt when new updates are available
  • run a disk defrag program to organise your files.
  • run a clean up to delete unneeded files
  • Register your software products
  • Schedule automated updates


POWER ISSUES

  • surges in electrical power can harm your computer
  • get a good surge protector with multiple plugs and on / off switch
  • avoid cheap ones with a metal oxide varistor (MOV) suppressor that can fail
  • buy a surge protector with included insurance to cover damage to equipment
  • protects your computer even when turned off
  • if you don't have a surge protector, unplug your equipment when not using
  • be particularly careful during storms or when it is lightning

PUTTING A STOP TO SPYING

  • install a good spyware program (Spybot, AdAware, etc.)
  • tracks down programs secretly monitoring your computer activities
  • these programs may have been installed through internet downloads
  • can also be installed surreptitiously when installing other programs
  • know where programs are coming from before downloading from internet
  • research the software provider and make sure they are legitimate
  • run spyware program weekly to clean out rogue programs from hard drive


STAYING AWAY FROM TROUBLE

  • don't accept software or downloads from unconfirmed sources
  • many viruses embedded in email attachments and activated when opened
  • set your email program so it doesn't open "preview" window
  • delete any suspicious email without opening it
  • don't open attachments unless you know who and where they came from
  • .exe, .com, .vbs, .bat, .mdb, .reg, and .js file extensions are dangerous

Tips to repair scratched Cd's at home

Even though cd's and dvd's are practically disposable now, there is always a precious cd you cannot afford to have damaged. Here are some of my tips to prevent loss of your favorite cd's.
Prevention comes first.
Care for your CD's or dvd's by handling and storing them correctly. Even your sticky fingerprints can damage layers of a cd's surface. For extra precious cd's you should definitely create a backup copy of it. If you do this there is no need to read the rest of this article.

Home Repair

When I have a problem with a cd the first thing I do is try to make a backup copy of it. It sometimes depends on the quality of your burner as to whether it can read your disk or not. You should slow down the read and burning speed so your burned gets an accurate image of the disk. I had lots of luck with Clone Cd.

The next thing I do is take my disc to my local video rental place where they restore and polish my cd's for free because I am a member. Some places charge money, but it won't be much.
The other alternative is to give it a clean yourself. Clean with soapy water and a soft cloth if it is just dirty. Only wipe from the centre of the cd towards the outer edge. Do not towel dry, leave to air dry, never in the sun.

If there are scratches there are two options. To polish the scratches out or to fill them.
1.To polish a cd you should use a soft cloth with some water and toothpaste. This will work as a mild abrasive. Do not rub too hard, be gentle, always from the centre and out. Make sure you clean all the toothpaste off by rinsing with water and air drying before testing it in your cd drive.

2.To polish and fill the most common thing people use is brasso. Follow the instructions on the bottle for safety and again, be gentle. Wash or polish off and air dry.
The best way to save your disks is definitely prevention. Go and make backups of your favorite disk right now..It will save you the headache.
