Fisher does a good job of reminding us of the basics of computer repair. Using the KISS method when applying these tips will keep you and your hardware safe.

by Tim Fisher

In addition to being an afternoon of great fun, PC repair can save you loads of time and money. No amount of fun, money or time is enough, though, to compromise your safety.

Keep these important tips in mind as you work inside your computer: Remember to Flip the Switch Always, always, always remember to turn the power off before servicing anything. This should always be your first step. Do not even open the computer case unless the power is turned off. Many computers have a number of lights inside to serve certain functions so check to see that no lights are on. If any are still on then the power is probably not completely off.

Unplug for Extra Safety As a second precaution, it is wise to unplug the computer from the wall or power strip. If there was any doubt as to whether the computer was off before, it’s settled now.

Avoid Capacitors Capacitors are miniature electronic components contained in many of the parts inside a PC. Capacitors can store electric charge for a short while after the power is turned off so it’s a wise decision to wait a few minutes after pulling the plug before working on your PC.

Never Service the Non-Serviceable When you come across labels that say “No serviceable components inside” don’t take it as a challenge. Some parts of a computer are just not meant to be repaired, even by most professional computer repair persons. You will usually see this warning on power supply units but you may also see them on monitors, hard drives, optical drives and other dangerous or highly sensitive components.

John Dow has some good ideas about passwords. He passes along a secret that you don’t want to miss. Read on!

By John Dow

I spend a lot of time cracking passwords! No, not for stealing software or information, for doing computer repair! One of the most common home or small business computer service repair calls I get is that Bob, fill in the blank here – lost his password / forgot his password / left the company and never told anyone his password, and we can’t use the computer or software.

If you have physical access, most times you can reset a password on any version of Windows XP. Some vertical applications get a little trickier but I still can usually figure out a way to get in to clear the existing password and then let the customer reset it.

And no, I’m not going to teach you how in this article, sorry. But what I can do is help you figure out a way to never forget a password without writing down. An especially bad practice that I see all the time is someone will write down the password on a post-it note and put it on the monitor. Which is a particularly ugly breach in security.

But I can understand the problem. Chances are you have many passwords to remember if you use a computer at home or at work. And since many of the systems automatically force the user to change their password every 90 days, this becomes quite a challenge to remember them all.

There are some good ways to create a password so that you can’t forget it. And you can easily meet the minimum requirements of at least 8 characters with at least three being punctuation or numerals too. But the best is 15 characters (I won’t go technical on you but let’s just say that the stored password of over 14 characters are much more difficult to crack). I can’t even remember who taught me this method but I’ve been using it for years.

The first thing to remember is not to use children’s names, birthdays, or any information that someone might guess. This includes common names found in the dictionary or some other know source. The reason for this is there are many cracker programs out there that use these common sources to check against password to break them. So stay away from common words or expressions.

Even the programs that generate random characters can be beat by another program designed to emulate that type of software. The idea behind them is good and they can provide a stronger password but for most user that creates a bigger problem since who can remember W#8hY*2l-Km$!1d, let alone type it.

So what’s the secret? The easiest way I’ve found to remember a password is to associate it with a person or event that you’ll never forget. Something that even a good friend might not know but also something that you couldn’t forget even if you wanted to if you tried.

If the password is for windows or a windows program you have up to 127 characters most times. So use a phrase instead of just one word. So if you have a phrase (or song lyric) burned into your brain you could use it too. When I need a quick password when working at a client’s I normally look at the machine or something on the wall and use it for the password. One of my favorites is “I hate Compaq’s model 2780!” or use any computer name).

When I was five we moved to the corner of 85th street and pacific. Most people I know now don’t know that and I doubt it would come up in any conversation. So if I used 085TH@pacificst5 that contains something I can easily remember and also meets the high end password requirements.

Or how about the first love of my life (which dumped me in about 2 weeks)? I won’t use her real name to protect the guilty but here’s that one, 2wKJeN06.OrGan, I added organ since she was organic (I think). See how this works? I’ll bet we all have lots of things, events, people, and the date or age we experienced them to use.

One weakness any password can have is if someone slips in a keylogger program on your computer. Keyloggers record all the keystrokes that a user makes and regardless how tough you make your password, if they can see the key strokes, they’ve got you. And it’s much easier than you think to do a stealth install.

There is one way to get around this issue, use extended characters. If you hold down the alt key, then press one or more numerals you get one of those weird characters with double dots on top or a symbol. But the keylogger still shows the character, but a way around it is to use Alt 0160. This extended character is a space and hides the fact that you used the Alt method to create it. So they won’t be able to duplicate it even if they see it.

There is no perfect solution for passwords. But you can and should take some steps to insure that you take the appropriate precautions whenever you create one. Keep it over 15 characters, use numerals, punctuation, and alphabetical characters. Combine elements that are easy to remember but not common information like birth dates or children’s names. Use associations that make it easy to remember.

And never communicate your password in any documentation or emails. Don’t display them on your computer or loan them to friends or associates. Random generators can be helpful but aren’t bullet proof. Change your passwords on a regular basis just in case. Always have a master or Administrator password that can be used to go in and change user’s passwords when necessary.

I’d much rather fix hardware or software problems than crack passwords on a computer repair service call. It makes my job a little easier and can save you a lot of money.

Nothing can be more frustrating than to have your computer freeze up, run slow or lock up. Especially if your trying to meet a deadline. I have to be honest, technology has spoiled me. Computers run faster, and internet connections run faster than ever. So when my computer starts to slow down or freeze up, I get pretty aggravated.

Learn how to quickly fix and provent this from happening. Read the article below but if you want major improvement then you need to look at ErrorDoctor.


Troubleshooting Computer Freeze (Lockup) Problems
By Michael Woodford

How familiar does the following sound? Your computer was working fine, but then suddenly started locking up (aka hanging or freezing), rebooting itself (crashing) or shutting down spontaneously? If you know only too well what I am talking about, then read on! Performing the simple steps below can fix the majority of lockup cases.

1. Check for recently installed software or hardware.
If the lockups started to happen after you installed a new peace of hardware, new software program, or new drivers, uninstall it and see if the problem goes away.

2. Run your antivirus program.
One of the first things to do in the case of sudden lockups is to run your antivirus program. Check your antivirus manufacturer’s website for updates and latest virus definition files. (This is absolutely necessary, outdated antivirus is not going to be of any use!) If you don’t have antivirus software installed - or if updates are unavailable - run one of the web-based antivirus scans that some major antivirus vendors like Trend Micro are offering for free. You can find a comprehensive list of available web-based scans and free antivirus programs on http://www.free-antivirus.info.

3. Run some good spyware removal tool.
If your machine is not infected with any viruses, it is still possible that it has some harmful adware or spyware is present. Download and run some good spyware removal tool such as AdAware or Microsoft AntiSpyware. Check http://www.free-antivirus.info for a list of free spyware removal applications.

4. Check for free hard drive space.
When no viruses are found, check out free hard drive space on drive C:. Make sure there is more than 20% of free space available; low disk space can lead to random lockups.

5. Check for overheating.
Overheating is another known cause of lockups. It can be caused by problems with fans inside the case, dust buildup, or other cooling problems. Make sure the power supply fan and CPU fan are running and free of dust buildup. You can check the temperatures inside the case by running Motherboard monitor http://mbm.livewiredev.com - make sure the temperatures are within the preset limits. Be very careful while cleaning inside the computer case (use plastic vacuum crevice tool) and NEVER OPEN THE POWER SUPPLY CASE as it contains high voltage.

6. Check the hard disk.
Check the hard disk - it is possible that its logical structure is corrupted. To check the disk for errors, right-click on the disk C: icon in “My Computer”, select the “Tools” tab, check all check boxes in the “Check disk options” field, and press the “Check now” button. It should ask whether you want to schedule the check next time you restart your computer - answer “Yes” and restart your PC. The check will be performed automatically after startup; it can take a while, so be patient. The program will attempt to fix some problems automatically – however, if the hard disk is failing physically, it will need to be replaced. It is also a good idea to run Disk Defragmenter (located in Start Menu > Programs > Accessories > System Tools) to optimize data placement on the hard disk for increased performance and reliability.

7. Check the memory.
Sometimes random lockups can be attributed to the computer memory (RAM) starting to fail. You can test the memory by running Windows Memory Diagnostic that can be downloaded from http://oca.microsoft.com/en/windiag.asp. If memory problems are found, try re-seating the RAM (pull it out and plug it back in). If it doesn’t work, replace the defective RAM.

8. Check for other hardware problems (advanced users).
More hardware-related problems can be diagnosed by running hardware tests from the Ultimate Boot CD that can be downloaded from http://www.ultimatebootcd.com. However, you should only use it if you know what are you doing - some programs on that CD can be dangerous when used inappropriately (for example, some of them can wipe the contents of your hard disk).

9. Update Windows and drivers.
Some lockups can be caused by outdated software components - update your windows and drives by running a windows update: http://windowsupdate.microsoft.com (it’s good idea to run it regularly).

The above steps will help diagnose and eliminate the most common causes of lockups. Hundreds more of other possible scenarios need to be dealt with on a case-by-case basis, as it all goes down to your particular computer configuration. Asking on PC troubleshooting forums/newsgroups should help you figure out solutions to not-so-obvious lockup cases.

Deception Runs Deep and Wide!

Recently I stumbled on an excellent article in Spyware Confidential, posted by Suzi Turner.  The article, “Edelman on ‘Deceptive Door Openers’ and Ask Toolbars”, addressed the use of false pretenses to get unsuspecting visitors to install the Ask Toolbar.  Enticement was used through “smiley faces” and other “cute downloads.”

The problem is that this opens the door to changes on your browser that may not be advantagous to you.  For instance, when you do a search using the Ask search box you will be exposed to more ads…

I recommend you read this article for further detail.  It seems that many of the big players are using these deceptive tactics to get on yur desktop.  Beware!

  1. You turn the PC on, it loads through and then reports it cannot find the C Drive

This sounds like a fault hard disk, swap it with another from a working PC, if the problem resolves this way then your drive is bad. The hard drive is found inside the case, it will have a ribbon attached to the mainboard and one of the power leads from the PSU. It is fixed with screws into the case, undo these, whip out the cables and get yourself a new disk.

Sometimes a reboot will give your disk a little more life, if a reboot does help, then make sure you backup your data straight away and get a new disk in there! This is a best case scenario, normally if the C Drive dies you lose all your data, if you can save it this way then you were lucky! Read more
