If It Ain't Broke, Don't Fix It*

There is something wonderful in this simple philosophy. It certainly is an aggravation saver, and I believe it is a good, honest, tip for a happier life. It is applicable in all aspects of our daily lives -- including our tech gadgets.

Some people (me), though, have some malformed gene, or mis-wired section in their brain which renders them constitutionally incapable of keeping their mischievous little fingers off of a perfectly functioning device. These people have a strange compulsion to try to "make it better". They just have to open it up and look at what's inside...
A highly Scientific Study (that I just made up) has proven that a full 9-out-of-10 of these personality-types not only fail to "improve" the device, they fail to get all the piecesTim the Toolman back inside, much less back in their proper places.

The modern name for these people is "tweaker". The most 'famous' tweaker was probably Tim ["the tool man"] Taylor, a character made famous by Tim Allen on Home Improvement. (I loved it when he "improved" the kitchen garbage disposal by powering it with a chainsaw engine.) His motto: More power!

Yes, "if it ain't broke, don't fix it" is a very good Rule. For that 90% of tweakers who only succeed in disassembling the object of their interest, it ought to be a Law. However (you, Dear Reader, were expecting a "however", right?), tweaking can be a good thing. Tweaking sometimes leads to Invention. Successful and repeatable tweaks are called "optimizing". And who can argue against optimizing? Not me. A great deal of Tech--for Everyone is about optimizing your PC.. such as today's tip.

Tip of the day: Optimize your computer with the latest device drivers. Most of my readers should be aware of the existence of the small programs that allow the software on our machines (primarily the OS) to interact with the hardware, which are called "device drivers". If you've ever added a new device, you (typically) had to put in a CD and install the "driver" to get it operational. My readers probably also know that, like other programs, drivers get "updated", and improved, occasionally. Did you also know that by seeking out, and installing the latest drivers, you can have a faster machine? Or, that your device may suddenly have more "features" and capabilities? Today I'm going to show you a method to use that I consider the first step, and tomorrow I'll describe the more aggressive and effective approach, as well as how to "undo" a driver update if things should go wrong.

The first step is to create a System Restore point, to give yourself a fallback position. I reco doing this whenever you make significant changes to your machine. (To see my series on the System Restore tool, click here.)

Then you need to access your Device Manager tool. There are a couple of ways to do this, but I use Start >right-click My Computer >Properties >Hardware tab >Device Manager. Now you will see a list of the components on your machine, as shown in the example below.
devmgr.jpgSome, in fact most, of these items you do not need to worry about updating. The items that typically will give you the most improvement are: graphics, sound, printer, network (or modem) adapter, and (sometimes) monitor.

Begin by selecting the device you want to update the driver for -- I am going to use for demonstration the sound on a laptop computer -- and 'expand' the hardware list by clicking on the "+" sign next to the proper category, in my example that will be the "Sound, video, and game controllers" category.

Next, double-click on the device name to open its Properties dialogue window. In my case that's "ESS Maestro PCI Audio", and then click on the Drivers tab, which will now open a window that looks like this.
snddrvr.jpg
Now click on the Update driver button, which launches an automated process called the "Hardware Update Wizard". Accept the default radio button setting ("Automatically") and click "next".

Now Windows will go out and "search" for a "better" driver than the current version, and when it finds one, will help you install it via a couple of "Next" clicks. Do this for all the devices (device types) that I listed above.
Unfortunately, the  most common result of the search returns this window.
cannot.jpg
This is because Microsoft has built into the search parameters a complex formula of what constitutes "better". To them, better does not just mean "newer" (ie, a more recent version number), but whether or not the driver has been tested and approved in the Microsoft labs (for a fee), and whether or not the driver's author has shelled out the dough to buy a digital "certificate" (for another fee).
Since this is a simple driver, and not a new miracle accounting program, or other retail piece of code, most authors skip these expensive steps... and so the Update search will disregard these drivers as if they didn't exist. Tomorrows post will deal with this issue.

But doing this process can and does produce results, and it is the method I reco as the first step in a faster/better PC. New drivers are released all the time, so I do this every so often.

To read Part 2, click here.

Today's free link: I have reco'd the popular Mozilla Firefox web browser here before, and I think it's only fair to tell you of another -- Avant uses the IE 7 rendering engine, but advertises itself as the "fastest browser on earth". I like it for its built-in security features, such as tracks erasing, and its rss reader. Take a look at the Avant homepage, and then give it a try.

Troubleshooting the Blue Screen Of Death

BSOD's, spontaneous reboots, freezing, and "incorrect password" lockouts. Bad computer. Bad.

bsod.jpg

Ah yes, the Blue Screen of Death. I sincerely hope you never see this rascal. The BSOD, or more properly, the Windows Stop Message, occurs when Windows detects a problem from which it cannot recover. The operating system halts and 'diagnostic information' is displayed on a blue screen as a series of hexadecimal numbers (there actually are a few humans capable of understanding, and using this information to effect repairs...but as far as I know, they all live in Seattle) which, frankly, will be of little use to the average user. Usually, a simple reboot resolves the issue. But sometimes it doesn't--you reboot, Windows loads, you get the Welcome screen, and bingo! BSOD. Wash/rinse/repeat. Aargh!!!

If this happens to you, the odds are pretty good that you have (quite recently) added a new device (or card) or memory module to your machine, or installed a program that your machine just doesn't like.
If it was a module, device, or card, try removing it and restoring your machine to the way it was before the install. If you run for a day or so with no BSOD's, then you can be fairly sure you've found the culprit. It may be that the device is defective. It may be that you didn't install it exactly correctly [maybe it didn't "seat" all the way into its slot?], or maybe your machine was being fussy the day you installed? Don't give up on your new card/device/module just yet. Go to the manufacturer's Website and download the latest device driver for your version of Windows, and "unzip" and install it (by double-clicking on the downloaded file). Then reinstall your card/device/module--taking extra care to fully seat it, and double check your wires and cables--and reboot. If it is a defective unit, it will not be long before our friend the BSOD revisits...return the unit to the seller (or manufacturer) for exchange or refund.

If you suspect a recently installed application (or...Microsoft Update) is the cause, then use the Add/Remove Programs tool to uninstall it. (XP+older: Start> Control Panel> Add/Remove Programs, Vista: Start> Control Panel> Uninstall a program.) [Note: in Vista, uninstalling Updates is done through Windows Update itself, not Add/Remove.]
If you are unable to get into Windows, reboot and start hitting the F8 key to get into Safe Mode. [For more info, click here] Again, run for a day or two, and if you do not experience any BSOD's, you've (most likely) found the perp. Again, you need not despair and abandon the program. It may have simply been an incomplete or corrupted install that was causing the stop errors. Try reinstalling it, but first make sure that there are no other applications running--turn off your AV, your IM, and close IE. You will soon know whether it is simply an incompatible or poorly written application.

I am going to stop here, but I want to acknowledge that this is far from a complete discussion on all the possible causes (nor cures) for BSOD's and the other woes mentioned at the top of this post. I will return to this topic again, and I invite your comments and critiques, and suggestions. I close by suggesting you also read my article on the Windows System Restore tool (click here) and reminding you that -- should all your efforts fail, my services are available at http://aplusca.com/

Today's free link: Sandra Lite from SiSoft. This is a benchmarking and system analysis tool that shows you a wealth of information about the workings of your computer, and detects areas that aren't working as well as they should.

Get a boost from your thumb drive

Thumb drives are amazing. They're fast, they're small, they make great keychain fobs, and they're affordable. I have seen 8GB thumb drives for as little as $30, and 16GB's for $50.
That's right-- sixteen billion bytes. (The hard drive on my P-II [still running] is 4.3GB's.)

Yes, thumb drives are all those things, and they're practical too. By purchasing a U3 drive, or downloading the Portable Apps suite, you can easily convert your thumb drive to a "computer on a stick" and run your applications from it (as opposed to the host computer). This can be particularly useful when traveling, as you can carry your bookmarks, contacts, and documents with you.. and you won't leave histories and 'tracks' that someone can read later.

In this article, http://techpaul.wordpress.com/2007/12/12/how-to-install-a-program-on-your-thumb-drive/, I tell you the steps for installing (pretty much) any program onto your thumb drive. By doing so, you can load your favorite, and most useful programs onto your computer-on-a-stick.. allowing you to carry a computer on your keychain (sort of).
I recommend loading a antivirus, and a couple of anti-spyware onto your thumb drives, and -- since thumb drives are small and "losable"-- using encryption to render the drive unreadable without knowing the password.

In another article, http://techpaul.wordpress.com/2007/06/28/put-your-thumb-drive-to-work/, I describe how to make a thumb drive "bootable", and how you can load it up with diagnostic and repair programs; thus turning it into a recovery tool, and portable repair kit-on-a-stick. (This is for the more geek-inclined, but there is some good information there even if you aren't skilled in computer repair.)

But even if you aren't interested in using a "computer on a stick", Vista users can still get some extra mileage out of your drive that you might not be aware of...
Tip of the day: Improve Vista's performance with ReadyBoost. Loyal readers of this series will already know that 1) Vista is a resource hog, and 2) the best way to improve Vista's performance is to give it lots of RAM. Well, the flash memory in your thumb drive may be fast enough for Vista to use as additional RAM (this is determined by the make/model of your thumb drive. Typically, the discount, or generic drives are not fast enough).

When you plug in a thumb drive, a small window opens which provides a list of options of what you want to do with this device-- one of the options is "speed up my system". Select this, and another window opens; click "Use this device". If your thumb drive is capable of ReadyBoost, you'll see a slider which allows you to allocate how much of your drive's room you want to give over to the Vista OS-- accepting the default is fine.
That's it. You're done. Pretty painless way to add RAM, eh? (cheap, too.)

Today's free link: today's free link is a repeat, but it is simply the best way to encrypt your volumes (drives), files and/or folders -- such as your thumb drive. Download the free TrueCrypt, and make sure a lost thumb drive won't be a minor disaster.

Problem Exists: between chair and keyboard

PEBCAK: The problem exists between the chair and the keyboard.

Ten-T Error: This error code is visual, like a vanity license plate-- ID:10T.

This is how Tech Support people used to refer to the Number One Cause of all technical support service calls (Help Desk)-- Operator Error.
People who use computers (and other "high tech" devices) don't always know what they're doing.. or fully understand the mechanics behind the cause-and-effect.
People generally don't read the manual. They turn it on and go.

Yes folks, when you give us a call, the odds are good we're not going to diagnose a true software misconfiguration or hardware malfunction.. we're going to figure out what you are doing wrong. We tech support-types need to be Behaviorists, Psychologists, Counselors, and Professors before we even start learning about Windows or command lines.

Needless to say, people who work at the Help Desk have heard some truly astounding Ten-T errors. And being people too, they tell their co-workers about the more memorable ones. In fact there are some legendary 10-T's in the PEBCAK Hall of Fame, which have been so oft-repeated that their origin is untraceable.. for example the lady who thought her CD-ROM's tray was a cup-holder. Or..

Call #1

TechSupt: "Okay, now close the window and.."
Caller: "Okay. Hold on." clunk (puts phone down)
Footsteps.
Scrape/thunk.
Footsteps.
Caller: "Okay, I closed the window.. but I don't see how that's going to help my computer problem."

Call#2
Caller: "I just got your new computer home and out of the boxes and all set up.. but it won't turn on. Something is seriously wrong with it, and I want my money back."
TechSupt: "Did you plug it in?"
Caller hangs up.

I will tell you that the calls that come in to me at Aplus Computer Aid are almost never Ten-T errors. I do not have one personal humorous story to share with you; 99.9% of all of my calls have been real issues that needed professional help.
I do not think this is due to people being any smarter today than they were ten years ago (hah!), but is due to the fact that the technology has improved/"matured", and we have been using it longer. Plug 'N Play mostly works, and DOS is long gone. Still..

Tip(s) of the day: RTFM (read the *freaking* manual). Sure, it is easier to buy a new gizmo, gadget, or doodad, bring it home and take it over to your geeky friend/relative/co-worker/neighbor and ask them to show you how to use it.
And, yes, the manual that comes with your gadget has too many pages.. and the grammar isn't always the best.. but here is how you learn THE CORRECT METHODS for using your device.. and not Fred's* best guesses at how to use it.
Also.. those blinking lights and confusing menus and strange-looking icons are explained.

FAQ stands for "frequently asked questions", and almost every device manufacturer has FAQ's posted on their Website. These are the "How do I..?" and "What does xyz mean?" questions and answers that new users typically have. You will probably find the answer you're looking for here, without having to go bother Fred*.
Some manufacturer's call this page "Support".

Owner's manuals and FAQ pages can prevent you from making it into the PEBCAK Hall of Shame.

Today's free link: Loyal Friends and True of this series know that I like to post lighter, more "fun" links on Friday's and today is no exception. A wonderful collection of humorous tech support questions and Ten-T errors can be found here.
Explore the various 'categories' and get a glimpse of what life is like for tech support persons, and a good laugh or two as well (and odds are good, you'll feel smarter afterwards too).

March Madness repost: Infected picture frames

An unexpected interruption has delayed the writing of the "using Certificates to encrypt your e-mail" post, and it may not appear until much later on today. In the meantime, I am re-posting a recent article. This post appeared as "Cyber Crime News", 2/16/08.
Nowadays, all you need to do is plug in a digital picture frame, and you lose your life savings.
Sound unbelievable? Guess again.

* Regular readers of this series should know that the hackers and viruses/malware of today aren't about ego, or twisted maliciousness, but are all about profit -- namely getting your money. It is cyber-crime, and you are the target. Your computer is their weapon.
* Regular readers will know that phishers send spam e-mails which contain links to fraudulent, malware-laden websites in the hopes that you will enter your account password so they can steal your identity (and drain your funds); and they know that merely visiting this site will "drive-by download" spyware (such as a keylogger) onto you machine, which will eventually report your logins... or anything else you type, like, your credit card number. [note:in April 2007, Google reported that it had found "hundreds of thousands" of webpages serving up malware.]
* Regular readers know that these hackers use trojan horses (a type of worm) to install a backdoor on your machine and turn it into a zombie (aka "bot", short for 'robot') under their control [ http://techpaul.wordpress.com/2007/06/14/the-fbi-and-operation-bot-roast/ ] which they then use, however they like, as part of their botnet. Typically, they use your machine to send spam and copies of the trojan horse (to make their network of bots larger) itself.

All very depressing stuff.

But what you may not already know, Dear Reader, is that these cyber-criminals are always looking for new ways to infect your machine, for the uses mentioned above, (okay; you might have figured that, though) and the method they're trying for is through the use of USB devices. So that, when we plug in our thumb-drive it infects our machine.. and any other machine we plug it into. The bad guys know that antivirus tools don't scan USB storage devices before they're opened ("accessed"). Because of this fact, I am very leery of thumb-drive give-away's (free gifts) and generally decline to reach into the bowl.

A security nightmare come true: What if the virus writers and cyber-criminals could get in cahoots with the device manufacturers (or, someone who works there) and pre-install their malware onto brand-new devices? Well, you would go to your local MegaGigaMart* and buy a new device, open the box (or 'blister pak'), plug it in, and bingo!, you're identity is stolen, fraud is committed in your name, your accounts are drained.. and your life is ruined. And consider this, folks-- darned near everything is made in China. If that isn't scary enough, what if the malware was undetectable? What if it could shut down all known antivirus programs? Don't laugh: it's real.

There are, right now, digital picture frames (which connect via USB) coming from the (Chinese) factory with a trojan horse pre-installed (and a while back, a few iPods were infected at the factory). This trojan seems to be -- for now -- limiting itself to stealing online gaming identities, but displays the fierce anti-removal characteristics of truly advanced malware. If it can be programmed to steal gaming identities (do I need to say it?) in version 1.0, who knows what 2.0 will be designed to steal?Scary, scary (and depressing) stuff.

Today's free link: For more details on the digital picture frame infection, please read Deborah Gage's article; "Trojan Horse probing defenses-- New virus is smart, aggressive and blocks antivirus protection at will", published in the San Francisco Chronicle, Friday, Feb. 15th. 2008. Business Section.

* Beware of "Hillary video" e-mail. (Source= Symantec) Spammers are taking advantage of the election season to send a poisoned link (it downloads a trojan) in an e-mail promising a video of an interview with Hillary Clinton. For details, click here.
