Computer Maintenance Tips

Just about everything needs to be “maintained” on a regular basis to stay “healthy” including our computers… Here are a few simple things to do, to be sure that your computer lives a long healthy and happy life and stays out of the “computer hospital”…



  1. First and foremost, make sure you back-up your computer system and data on a regular basis. This is critical in case your system ever crashes or is infected with a major virus… Whether you back-up manually or automatically, whether you use a 3rd party (such as carbonite.com or mozy.com) or you back-up to a DVD, CD, flash drive, portable hard drive or external hard drive, making sure your system is totally backed up is one of the most important maintenance steps to ensure that you don’t lose valuable information including your data, photos, videos, music etc.


  2. Make sure your computer is up-to-date on it’s “shots” which means making sure that your computer is protected with anti-virus & spyware software. And just as important, you want to be sure this software is “current” meaning you must accept and allowing the updates for your anti-virus, adware, spyware and malware program on a regular basis. It’s also highly recommended that you protect your privacy by using a firewall… Together, all of these help to protect your computer, the information on it as well as your personal information.


  3. Updates are important not only for your anti-virus, but also for your operating system – application programs and drivers for your peripheral hardware, such as your scanner, printer and other hardware…


  4. Know the specifics about all your equipment and programs – it helps to create a list of your equipment including mfg, model #’s, serial numbers, when they were purchased, and other important data, such as cartridge #’s; specifics about your digital cameras, camcorders, cell/smart phones and programs – and in one place along with the receipts, so that you can quickly and easily access the information when you are talking to a technical support person. It also helps to keep the basic information for all on a small card in your wallet, that you can refer to when you are shopping or asking for technical advice


  5. Protect your computer (and all electronics in your home) from “power surges and drops”.. Use a surge suppressor, which contain technology that prevent excess amounts of electricity from entering your computer – Computers especially, are highly sensitive to electrical fluctuations a surge protector that help “even out” power spikes… So whether you have a desktop or laptop, you need surge protection…If you have a home office, you may want to consider also using a UPS (uninterrupted power supply) which often times has a built in surge suppressor/protector.


  6. For those of you who carry around laptops, notebooks or netbooks – portable devices should be carried in “protective/padded cases” and if you are leaving your desktop for a long period of time, consider covering it when it is off and not being used……


  7. Ventilation is important. It’s never a good idea to cover the back of a desktop – the vents & fans - with anything that could prevent airflow. Some people, often those with pets or live in areas that tend to be dusty, thinks it’s beneficial to protect their computers and stop animal hair, dander & dust from entering their fans & vents, by covering them with pantyhose, cheesecloth etc., but they only cause more problems by preventing proper ventilation.. Laptops, notebooks and netbooks should be raised slightly from the surface-many new ones have small feet built in, or just add little Velcro furniture tabs under each corner, or use a small rack like those used in kitchen cabinets...


  8. For many years when your system began to run slowly the first recommendation made was to “clean out your cookies and temporary internet files” – although this isn’t as important now that the computer hard drives are so large, but there are still advantages to cleaning them out periodically..…


  9. Before you just hit the power button, be sure you have properly and completely closed all programs. Shutting down your operating system properly will ensure that you don’t corrupt any of your files, making them inaccessible in the future…


  10. Find a good technical support person that you trust – so that when you aren’t sure – you can call them. The last thing we want to do is touch something that could void our warranty or further damage our system…

WHAT IS A MEDIA PLAYER?

Basically it is “application software” that we use to play and manage all of our music and video files. By manage, it means that we can format music & video files to various formats; rip and burn our music & video files (so that you can transfer them to & from CD and or DVD) and many offer “visual effects” so when we listen to the music there are various patterns that will flash on our monitors (similar to screen savers).

Microsoft Operating Systems include a media player “Windows Media Player” and many people use iTunes Media Player so that they can synchronize their various iPod devices…

But personally – my favorite is VLC Media Player – which is also free… VLC works on most Operating systems including Windows 98 thru to Windows 7); and it can be installed and run from a flash drive and portable hard drive. I also think it’s one of the easiest media players to use to convert music and video formats and you can take screenshots of video’s you are watching which is a feature many people like… to download go to:

www.vlcmediaplayer.org or www.videolan.org

There are many others and it helps to check out these out at some of the “freeware” websites, such as:

www.download.cnet.com
www.freewarefiles.com

What is a computer virus?

A computer virus is a computer program that can copy itself and infect a computer without our permission or knowledge. The term "virus" is commonly but erroneously used to refer to other types of malware, adware & spyware programs that don’t have reproductive abilities.



  • A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a CD, DVD, or USB drive.

  • Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.

Viruses are very different (technically) from COMPUTER WORMS & TROJAN HORSES:



  • A WORM can use security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host

  • A TROJAN HORSE is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer system's hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but most are hidden. This makes it hard for most users to notice, find and disable and is why anti-virus programs are now commonplace
