Computer Maintenance is a good practice?

Regular computer cleaning is recommended to prevent overheating and glitches caused by dust inside your CPU. In addition to shorting out electronics, dust can act as an insulating blanket and prevent heat sinks and other components from cooling off. A few minutes of careful cleaning will remove the computer killing dust from your CPU's fans, heat sinks, electronics and case, allowing the heat to dissipate and cool air to flow unimpeded throughout your system.
Dust isn't just unattractive—it can potentially damage or even destroy parts of your computer. Cleaning your computer regularly will help you keep it working properly and avoid expensive repairs.
Computer systems can produce a considerable amount of heat. As such, inadequate/ineffective cooling of your PCs components can shorten their lifespan, degrade their performance, and even cause your computer to stop functioning completely until proper cooling is restored. Over time, dust and other airborne particles can build up inside your computer, reducing the effectiveness of its cooling systems. That’s why regular cleaning is necessary. But, before you pull out your trusty hand-held vacuum cleaner, consider this warning: static electricity kills computers! That’s why computer cleaning is best entrusted to computer repair professionals with specialized equipment.
Your computer is an electronic device that produces heat. And, as you probably know, too much heat is a bad thing for electronic devices. As such, heat must be dissipated (removed) in an effective manner. Just like humans use fans to keep cool during hot summer weather, computers likewise utilize fans to cool their various components. Here is a short list of computer parts that often have cooling fans:

 Processors (CPU)
 Power Supplies
 Video Cards
 Some motherboard chipsets
 A case intake and exhaust fan

And because all these fans are constantly moving air, and air contains dust particles, your computer’s cooling systems are a prime target for dust buildup. After a while, without being cleaned, your computer’s fans/heatsinks could look like this:

As you can imagine, all that dust severely inhibits the proper cooling of the component. Thus, keeping your computer’s cooling system properly maintained is an absolute must (if you desire reliability and peak performance from your PC). Just a side note; better quality computer cases (like the ones we use for Northbridge-built PCs) often integrate dust filters into the case intakes, drastically reducing the amount of dust entering the system.
What happens if your computer’s components begin to overheat. Some key points:

 Overheating causes a lot of noise in to your computer. (like fan noise).
 Overheating components have reduced lifespans. Cooler running computers generally last a lot longer.
 Overheating components can lead to reduced performance (thermal throttling on processors for example)
 Overheating components affect other components, as heat is distributed inside the computer chassis/case.
 Overheating components can cause your computer to stop functioning entirely, until proper cooling is restored

With that all said, let’s look at the solution: Regular cleaning. In most cases, a thorough cleaning once a year is sufficient, but it depends on the environment in which the computer is kept. If a computer is located in a dusty industrial environment, more frequent cleaning may be needed. Now, before you open up your computer and whip out your handy handheld vacuum cleaner, consider this warning: static electricity kills computers. What I’m trying to say is this,
NEVER use a regular, household vacuum cleaner to try and ‘clean out’ your computer! Never!
The static electricity generated by the vacuum can permanently destroy your computer’s sensitive components. That’s the reason why computer technicians often utilize specialized static-dissipating equipment when working on PCs. If you are interested in having your PC professionally cleaned, give Experts Computer Repair a call. Our skilled technicians use specialized equipment to help ensure your computer’s internal cooling systems will work reliably for years to come.

Cleaning your computer, components, and peripherals help keep everything in good working condition, helps prevent germs from spreading, and helps allow proper air flow.
Computers are some of the most efficient dust collectors. Aside from looking gross and possibly being an allergy hazard.

How often should I clean my computer?
The frequency of how often you should clean your computer varies on different factors. To help you determine how often you need to clean your computer call to Experts Computer Repair for a free consultation about your computer cleaning.

CD-ROM, DVD, and Other Disc Drive Cleaning
Why? A dirty CD-ROM drive or other disc drives can cause read errors when reading discs. These read errors could cause software installation issues or issues while running the program.

Hard Drive Cleaning
Why? Computer hard drives cannot be cleaned. However, they can be cleaned with software utilities to help it run fast and efficiently. Utilizing these utilities prevent the hard drive from slowing down.

Keyboard Cleaning
The computer keyboard is usually the most germ infected items in your home or office. A keyboard may even contain more bacteria than your toilet seat. Cleaning it helps remove any dangerous bacteria and keeps the keyboard working properly.

LCD/LED Cleaning
Why? Dirt, dust, and fingerprints can cause the computer screen to be difficult to read.

Motherboard Cleaning
Why? Dust and especially particles of cigarette smoke can build up and corrode circuitry, causing various problems such as computer lockups.

Mouse Cleaning
Optical or Laser Mouse
Why? A dirty optical or laser mouse can cause the mouse cursor to be difficult to move or move erratically.

Optical-Mechanical (Ball) Mouse
Why? A dirty optical-mechanical mouse (mouse with a ball) can cause the mouse to be difficult to move, as well as cause strange mouse movement.

Printer Cleaning
Why? Cleaning the outside of a printer can help keep the printer's appearance looking good and if used by many different people keep the printer clean of germs.

Scanner Cleaning
Why? Flatbed scanners commonly become dirty with dust, fingerprints, and hair. When the scanner is dirty, the images may have distortions.
Miscellaneous Cleaning Steps
Below are a listing of miscellaneous computer hardware that is rarely used today, but kept on this page people working on older computers and need to clean these devices.
Floppy drive cleaning
Why? Dirty read/write heads on the floppy drive can cause errors during the reading or writing process.

Keep it cool

Don't restrict airflow around your computer. A computer can generate a lot of heat, so the casing has fans that keep it from overheating. Avoid stacking papers, books, and other items around your computer.
Many computer desks have an enclosed compartment for the computer case. If you have this type of desk, you may want to position the case so it is not against the back side of the desk. If the compartment has a door, you may want to leave it open to improve airflow.
