Cleaning Your Desktop or Laptop Computer – Inside and Out

All computers require periodic cleaning. This is true for both laptop and desktop computers. It’s not just physical dust and debris; there are also junk files, malware remnants, temp files, program fragments and other computer software that needs to be tidied up on a regular basis. Here are the basics:

1. Computer screen: Turn off the monitor and find a dry, clean cloth. The cloth should be non-abrasive and lint-free. Then use the appropriate cleaner and apply it directly to the cloth, not to the monitor. This avoids drips that can damage electrical components. Gently wipe down the screen with gentle pressure. When cleaning a laptop screen, be especially careful not to get drips in the speakers or keyboard. In the absence of a cleaning agent, water can be used, preferably distilled. Otherwise use a non-ammonia based glass cleaner.

2. Keyboard: Use a can of compressed air and spray between the keys. In many cases, this is sufficient to clean out the crud under the keys. In most extreme cases, it may be necessary to pop out the keys with a pen. The underlying surface is then easily cleaned. Removing the keys is not recommended with laptops! However, a laptop keyboard can be replaced by your local computer repair shop. The key surfaces can be cleaned in a similar fashion as the monitor. Again, apply the cleaning agent to the cloth, not directly to the keyboard.

3. Cleaning Inside a Desktop: Most desktop cases are easily opened with a screwdriver or with the simple twist of a few thumbscrews. A can of compressed air can then be used to clean the fans, CPU heat sink, vents, motherboard, expansion slots, etc. Be sure to blow the debris away from the system when possible. If you have a laptop computer it also needs the inside of the case cleaned out periodically but I strongly recommend you take it to a qualified computer repair professional or computer repair shop for this. Tell them you want the fan basins cleaned out and the heat sink taken up and new thermal paste applied. This should be done once every three years and more often if you smoke or have long-haired pets in the house.

4. Clean the computer of‘software debris’: Depending on your preference, Windows has many utilities to keep your computer in good working condition; and, there are also many software programs available to help with this task. These programs tend to do a better job than windows utilities and are easier to use. One example is CCleaner. CCleaner provides a means to fix file problems, registry errors, repair broken shortcuts, delete junk files, etc. Running these utilities once every few weeks is one way to keep your computer running smoothly but it’s not a total solution.

5. Remove Malware: Although this may come as a surprise to many — your antivirus is no match for today’s infections. Some (and often many) will inevitably slip through your AV software. I suggest running a stronger aftermarket malware removal utility such as Malwarebytes to remove minor infections. Furthermore, you should take your computer into a qualified repair shop once a year for a professional virus check and removal.

Periodic cleaning of your laptop or desktop is a good way to keep your computer running smoothly, extend the life of your machine, and increase your overall computer using experience.

Things to Consider With A Free Email Account

While there are many advantages to using a paid-email service, there are many great options for those seeking a free email service. It’s not always easy to determine the differences, but a little bit of research can go a long way to finding the perfect service for your requirements.
 
What to look for:
 
1. Security: Where intentional or inadvertent, most of us store a plethora of personal and confidential information in our email accounts. Passwords, bank account / credit card information, and tax returns are just a few examples. Be sure your free email provider has multiple layers of protection.
 
2. Features: What does the service in question offer beyond the ability to send and receive email? How much storage is included? Is there a messaging app? A calendar feature? Is the ability to filter and sort your incoming email important to you?
 
3. Support: Does the provider have a good reputation with regards to help and support? It can be more than a little inconvenient if your email is down and no help is available. If you’re looking for service stability, the more popular services are usually a better bet.
 
Popular Free Providers:
 
1. Gmail: Google is everywhere. It’s difficult to not have a Gmail account. At the very least, a Gmail account is required for any real functionality with Youtube. Gmail includes a messaging and calling feature. There is even the ability to get a unique phone number that can be linked to your cell or home phone. Gmail arguably has the greatest functionality, but limits users to 10 GB of inbox storage.
 
2. Yahoo email: Yahoo email is still very popular, though has fallen out of favor in recent years. Many email users appreciate the ability to avoid the nesting that is forced upon users of Gmail. Yahoo boasts unlimited inbox storage, but lacks the cloud storage feature of Gmail.
 
3. Mail.com: This relative newcomer also has unlimited storage and the ability to utilize aliases to protect your identity. The maximum attachment size is 50 MB, falling between Gmail’s 20 MB limit and Outlook’s 300 MB limit.
 
4. Outlook.com: There’s a lot to like about Outlook’s email offering. Unlimited storage, 300 MB maximum attachment size, and 7 GB of cloud storage. While Outlook lacks Gmail’s video chat feature, it does include aliases, an RSS reader, and social media feeds. Outlook is growing in popularity and many users look to alternatives to Gmail and Yahoo email.
 
There are numerous free email providers, many more than listed above. Be sure to examine all the options before making a choice. Compare features, security, and support to find the one that is the best fit for you.
