What are codecs, and do I need them?

Tech News and Views

I was going to download the Linux Mint operating system for use on an old computer when I ran across the term "Codec". What are Codecs and do I need them?

The name codec is a short version of Encoding and Decoding which means compressing and decompressing of a media file. Codecs are used in video conferencing, streaming media and video editing. Linux Mint has built in codecs as does Windows Media Player.

CMOS battery replacement

Tech News and Views

I have frequently mentioned that if your computer clock keeps losing time it is an indication that the CMOS battery probably should be replaced. It's an easy job in a desktop computer but can be very difficult in a laptop. Most computers use a CR2032 watch battery. The batteries generally run about $2.50 if purchased individually. Ace Hardware often sells packages of 8 for $1.50.

Backups that are nearly useless

Tech News and Views

I recently assisted a user whose computer had crashed. I asked if he had a backup of his files and was very surprised to find that he had 2 portable external drives and both had backup info. However, when I connected the drives to another machine, I found that one drive hadn't been backedup since 2012. The other had a system image from 2015. Certainly, the user had changed most of the information in the intervening years. So, the backups were virtually useless.

If you want an effective backup, set up a schedule for the backups. Once a week is certainly not too often.

Get the dust out of the desktop

Tech News and Views

Many computer users are afraid to take apart their desktop computers to clean the interior of the machines. It's a simple process, and should be done at least once a year. Here's what to do. Note how the cables are attached to the rear of the machine. Make a diagram if you can't remember. Remove the cables. Most computers have one side that is removable. The side may have one or two screws holding it in place. Then slide the side off the computer case. Some computers have a handhold you can pull while others may have to be gently pried away with a screwdriver.

Take the machine outside. Spray all of the dirty areas with compressed air (You can buy a can of compressed air at Walmart and many computer stores. Reassemble the computer.

Easy way to put icon on desktop

Tech News and Views

Here's the easiest way I've ever encountered to put a new icon on the desktop. Use your search engine to find the page for which you'd like an icon. Let's say it's bankofamerica.com. Click in the address line and drag that address to the desktop. That's it.

If you can't see the desktop because the web page is too large, click on the restore down symbol at the top right of the page so you can see the desktop.

Restore missing icons in Windows

Tech News and Views

I was trying to help a computer user the other day by adding the Google Chrome browser to the desktop. I was a little surprised that the computer showed no icons, and when I tried to add a shortcut to the desktop, it wouldn't show up. Evidently, someone had tried, before me, to help the user with computer problems and had gone into a screen that lets the user turn off all the icons. I have no idea why you would want to turn them off, but, if they are off, here's how to turn them back on.

Right click on the desktop. Click View and then click to put a check before Show Desktop Icons.

Does it pay to upgrade an old computer?

Tech News and Views

Many people wonder if it pays to upgrade an old computer. The answer depends upon many factors. You need to know how much memory is in the computer, how much it will take, how many memory slots there are and, of course, the cost.

I recently upgraded a 6 year old computer. The machine was running Windows 7, and I had upgraded it to Windows 10 for free. It had 4 GB of memory (2 GB in each of 2 slots). I removed that memory and inserted two 4 GB sticks for a total of 8 GB. The cost for the new memory was $40.27 including tax and shipping.

I replaced the 500 GB mechanical drive with a 480 GB solid state drive. The cost was $130.

So, for $170.27 I greatly upgraded my computer. The machine is much faster than it was. If I had to purchase an equivalent machine, it would cost approximately $800.

Free anti-virus

Tech News and Views

Many people swear that their anti-virus program is the greatest thing since sliced bread. They may tout McAfee, Norton, Kapersky or some other paid program. I don't think these people know that Windows 10 contains a free anti-virus program called Windows Defender, and Defender works very well.

I am a great believer in free programs. There are many good free ones, so there is little reason to pay for most programs.

Reasons why wireless printer won't print

Tech News and Views

A wireless printer can stop printing for many reasons, but often it's careless use of the printer keyboard that causes the problem. Most printers have a wireless on/off switch. It is easy to mistakenly hit that button when you are trying to change one of the printer settings. So, you may turn off the wireless printing even though you had no intention of doing so.

When your printer doesn't print, it's tempting to try to print again, but that causes more problems, as the jobs build up in the print queue and that stops all jobs from printing. You should cancel all documents, make certain the wireless button is on and that the default printer has been chosen for the print job before trying to print again.

What is a VPN?

Tech News and Views

You may have heard the term VPN (virtual private network) and wondered what it means. Here's an excellent description from Worldstart:

A VPN (virtual private network) is a private connection to your network that can be accessed from any location. This makes VPNs very popular with businesses that may have remote workers who need to access the in-office network. VPNs additionally encrypt all of your outbound information. For example, when you are browsing the internet, a VPN will encrypt this information to prevent unauthorized users from seeing your data.

Most common computer problem

Tech News and Views

I get dozens of calls from users who ask how to solve computer problems. By far, the most common problem I hear about is loss of Internet connectivity. Let's look at why that problem exists.

Electrical surges and electrical interference can cause a modem and router to loose their handshaking ability. A simple reset often solves that problem. Just remove the power plug from the modem and router, wait 20 seconds or longer and plug both back in. Wait a minute or two and the computer should again connect to the Internet.

Two other reasons for the computer to lose connectivity include problems at the provider's end and failure of the modem or router. Component failure is rare, so look for handshaking problems first, then at the possibility of the provider being down and lastly at component failure.

Is that noise an indication of trouble ahead?

Tech News and Views

Computer noises can be worrisome. Typical noise sources are the computer fans, hard drives or optical drives. Many computers have fans that are designed to speed up when the computer is hot and slow down when the computer is cooler. Fans rarely quit working unless the computer is so dirty that the dirt impedes the blades from turning. Noises coming from optical drives are common and are usually not a sign of trouble. Ticking, coming from the hard drive is generally a sign that the drive is due for imminent failure.

How to recover Yahoo password

Tech News and Views

Yahoo has been hacked a few times and as a result the service is making it more difficult for users to log on. Two step verification seems to be the rule. After you go through the normal log on procedure, Yahoo wants users to use the mobile device to verify the log on.

If Yahoo asks you to log on from a mobile device, click on Yahoo email on your mobile phone. A code will appear and you just have to click on it. That will activate the email on your computer.

Why an ultralight computer might be a poor choice

Tech News and Views

Many users may be tempted to purchase ultralight computers because of their light weight and portability. But many ultralights have a serious defect. The batteries are often built in and can be nearly inaccessible.

To access the battery in one Dell computer I recently encountered, the user must remove a back panel, remove the memory, remove the optical drive, remove the keyboard and take off the palm rest. That process is not for the light of heart. Users will pay hefty service fees to have a professional change the battery.

By contrast, I recently changed the battery in my 17.3" laptop. Sliding a pair of locks released the battery. A replacement battery was purchased for $10 including shipping. The new battery just slid into place.

Watch out for new Silverlight scam

Tech News and Views

Worldstart recently ran the following warning that all users should heed:

Tricky hackers are targeting people with a particularly nasty type of malware containing a keylogger. The folks at Proofpoint Security first reported this threat. A keylogger will record everything that’s typed into a PC. What’s scarier is that these crooks have targeted financial companies. That means this malware would be recording account numbers, social security numbers, passwords, and other personal information that can be used to steal your money and your identity.

This malware is disguised as a Microsoft Word attachment with the name “info.doc". When you open the document, it asks you to install Microsoft Silverlight to view the content. If you click the “install” button, you’ll end up installing malware instead of Silverlight.
