Common Computer Problems and Fixes

Lifehacker.com has an article on how to Help Clueless Relatives with Their Computer Problems. These are common problems that come up with most PCs. By following this advice, you can fix your computer or the computer of those who consider you the computer expert in the family.

“It takes forever to start up.”

If your loved one has installed any software on the computer—especially ISP-specific packages that automatically include bundled add-ons—there’s no doubt unnecessary items have planted themselves into its startup. Use our complete guide to speeding up your startup to get rid of the stuff they don’t need, and save CPU cycles and time on boot-up.

“I keep getting a pop-up saying I need to pay for my antivirus software.”

If the default trialware antivirus software that came pre-installed is now bugging your clueless relative to pay for a subscription, uninstall it. Then, check out Lifehacker readers’ five favorite—and FREE—AV packages ready for download and installation. To fast-track to a free replacement, grab the free edition of AVG.

“When I get on the internet things look weird” or “I keep getting these annoying popup ads.”

Thoroughly check your relative’s PC for evidence of malware: like a hijacked web browser that redirects google.com to an Asian porn site, unsolicited pop-up ads, or suspicious programs named things like “Keypress Watcher.” If you suspect nefarious software has glommed onto Windows, get to scrubbing. Back in 2006, we ran down how to fix Mom and Dad’s malware-laden computer and the advice still stands. Go straight for a copy of Ad-Aware Free and Spybot Search & Destroy to get started.

Then, download and install Firefox, set it as the default browser, and replace all the IE shortcuts labeled “Internet” with the fox.

“I can’t find the digital photos I downloaded last month.”

If Aunt Bertha never gets the photos and videos she took with her digicam onto her computer—or she does, but they get lost in the abyss of her hard drive—make sure she has the right software to preview and find ’em. Install Picasa 3 and scan your loved one’s entire hard drive for digital photos to add them to the library.

Relatives who take digital home videos should also get a free copy of VLC installed to insure that they’ll be able to play any clip they’ve got.
“I’m running out of hard drive space.”

If Uncle Marty thinks he needs a new computer because he keeps getting a “low disk space” message, tell him all is not lost. Find out where all that gigabytage is going by visualizing his hard drive usage with free tools that will map what files are taking up what space. Then, declutter his hard drive of the bits and bytes he doesn’t need (and didn’t know he had).

“The internet stopped working.”

The worst family tech support situation to get in is one that involves no (or a very slow) internet connection. Before you head over to Cousin Bob’s house, load up a USB drive with the software you’ll need to troubleshoot things without a connection (or without a broadband connection). TechRadar compiles a list of fix-it tools you can take with you to the family holiday get-together.

Macs Solve These Problems

This list is for PCs only. Macs typically do not have any of these problems, so you might suggest that your relatives buy a Mac if they can afford it and they are regularly having trouble.

Remote Access

Another idea is to install LogMeIn (PC and Mac) on their computer and add their computer to your list so that you can fix problems when you aren’t there. iChat (on Mac) and VNC also work well to remotely control a computer and fix problems.

Computer Repair Flowcharts

Sept 5 2009 UPDATE TO POST: The author of these flowcharts, Morris Rosenthal, expressed concern about having his copyrighted material shown here. Therefore the links from the thumbnail images below were removed. Please see his Computer Repair with Diagnostic Flowcharts site for the full examples of his flowcharts or purchase his Computer Repair with Diagnostic Flowcharts book from Amazon.

—————–
Many DC area consultants use flowcharts and work flows in their jobs. If you’re interested in following the diagnostic process of computer repair specialists, take a look at these flowcharts by Morris Rosenthal. They illustrate many of my thought processes when fixing a computer problem.

Boot Failure Troubleshooting

The most comprehensive of these flowcharts is the Boot Failure Troubleshooting Flowchart which encompasses several smaller flowcharts. You can see that it is PC focused, asking you to run scandisk and FDISK on your hard drive. Still, the principles apply to any computer.

Many of these troubleshooting repair processes are illustrated individually in an easier to read and print format:

Power Supply Diagnostics

Power Supplies commonly break, especially if they are hit by a power surge (too much power, such as when hit by lightning), blackout (no power), or brownout (lower voltage power).

A power supply can die over time (booting occasionally) making it trickier to diagnose. Be sure to get a high enough wattage power supply, especially if you have a power hungry graphics card.

CPU, RAM and Motherboard Troubleshooting

RAM problems can be vexing because they might only appear when a particular part of the RAM is accessed. This can manifest itself through strange computer behaviors that are often mistaken for viruses.

Motherboards, known as Logic Boards in the Mac world, hold the RAM and CPU. Without replacement parts, it can be difficult to determine where the problem lies between these three components.

Hard Drive Failure

With spinning disks and moving heads, hard drives will eventually fail. Many of today’s laptop hard drives have accelerometers built-in so that they can protect the hard drive when you are moving the laptop. But the moving parts will eventually break. Studies show annual hard drive failure rates to be 2-13%, depending on usage and particular model used. Over the next 5 years there is expected to be a transition to primarily using solid state drives (SSDs) that can potentially last longer and use less energy.

This flowchart assumes the use of IDE hard drives, which are older than the standard SATA drives in today’s computers.

CD and DVD Troubleshooting

Again, this chart assumes that you are using an IDE connector, not today’s standard of SATA drives.

Other steps in drive diagnosis include:

  1. Listening to the drive. Bad hard drives and CD drives might actually sound bad, with grinding, straining, or clicking noises.
  2. Looking in the Windows Device Manager for driver issues. These may be fixed with new drivers, or might (for older IDE drives) require you to remove or change the setup of other devices.

Video Card Diagnostics

These video card diagnostics assume that you are using a discrete video card, not a motherboard with integrated video which are common in today’s lower cost computers.

Network Troubleshooting

This is another case where it is useful to have other computers available to determine if the problem is related to the network (cables, router, switch) or the computer.

Fixing Computers

These and other flowcharts are in Morris Rosenthal’s book:
Computer Repair with Diagnostic Flowcharts Revised Edition: Troubleshooting PC Hardware Problems from Boot Failure to Poor Performance

These flowcharts can give helpful hints to fixing computer problems. Unfortunately, they can’t cover all the latest technologies as they come out.

A couple of things that I do to diagnose and repair computers include:

  1. Testing with replacement parts. If the monitor doesn’t show video, you can hook up another monitor with another video cable to see if it’s the computer or monitor that is malfunctioning. If you suspect a bad power supply, you can try a working one.
  2. Perform a quick Google search. New computers often ship with a driver problem or needed updates that are easily fixed by searching Google or the knowledge database of the computer manufacturer.

VLC Media Player

VLC Media Player can play any kind of video or audio file you throw at it. Compared to Windows Media Player, it is very lightweight. It is available for Windows, Mac, and Linux.

For people who download videos or those who just want something simpler to play their MP3s, VLC is a popular alternative.

Microsoft is promising a smaller version of Windows Media Player as an option when Windows 7 arrives in late 2009. Until then, VLC easily beats it.

VLC is also a useful alternative to the Quicktime Player on the Mac. There are several formats that VLC supports which the Quicktime Player does not by default.

You can run more than one media player on a computer, so give VLC a try.

Backup your DVDs with HandBrake

HandBrake Rips DVDs

HandBrake is free open source software that can rip DVDs, meaning that it can make a backup of the video to your computer. HandBrake works very slickly and has multiple encryption options and presets for popular formats (ipod, PSP, Apple TV, etc.).

Originally just on Max OS X, HandBrake is now available on Windows.

You can keep your backup on your computer, on a small media device like an iPod, or burn it to CD or DVD.

MetaX adds Artwork

MetaX, also free, adds an image, description, and other info to the video. This allows you to, for example, see all your movies with associated artwork from within iTunes. Unfortunately, MetaX is only available for Mac OS X.

Missing Vista Recycle Bin

I recently saw a McLean, Virginia, customer’s new laptop with Vista that did not have the recycle bin (trash can) on the desktop by default. She couldn’t find it in the program list or by doing a search for “recycle bin”. Here’s how to get it back.

Right click on the desktop, then choose Personalize. On the left side menu, you should click Change desktop icons.

This will show you the desktop items that you can have appear. Most people will want Computer, Recycle Bin, and User’s Files checked off so that they are easily accessible from the desktop.
