Geek Tip: Reboot! Unplug and Re-plug!

Monday, October 6th, 2008

You’re trying out your new scanning software — it’s working great.  But a few hours later, it suddenly stops working.  Now what?

Reboot.

Over the years, I’ve found that true Geeks do this without thinking.  They reboot before trying anything else.  And you know what?  If the software had been working properly earlier, rebooting will get it to work against 9 times out of 10.  Maybe 99 times out of 100.

You’d be surprised how many really smart people (even some very Geeky people) view rebooting as a last resort.  I can understand that — after all, if the software had been working properly, why should rebooting help?  And anyway, who wants to sit around for 5 minutes, waiting for Windows XP to do its thing? 

Trust me — start rebooting, and go play some Super Metroid while you’re waiting.  If you do this routinely, you will save hours of frustration in a year.  (Or rather, you’ll substitute hours of Super Metroid frustration for hours of computer frustration…)

The hardware equivalent is to unplug and re-plug.  If the device is battery-powered, then remove the battery and reinstall it.  (This is different from using the on/off switch — you should actually disconnect the device from its power source.)  Most computers and peripherals these days are actually “sleeping” rather than truly “off” after you use the on/off switch to shut down.  Unplugging and re-plugging is often the only way to get a device to reset.  (There was a printer at my parents’ house that hadn’t worked in months – an unplug/re-plug got it working again in less than a minute.)

And if rebooting/re-plugging doesn’t work?  Now you can start digging through the manual and Googling.

Good luck!

Stupid Geek Tip: Cleaning a Dry Erase Board

Wednesday, September 3rd, 2008

It’s annoying — your whiteboard eraser doesn’t seem to be doing the trick.  You don’t want to walk down the hall to look for that cleaning liquid you’re supposed to use.  But those residual marks are distracting!  What to do?

Here’s a tip — you can use your dry erase marker as a quickie board cleaner.  (This only works if you have one of those smelly markers.  If you only have low-odor markers, you’re going to have to make that walk down the hall.)

Just pretend your marker tip is an applicator for a magical cleaning formula.  Liberally apply the magical formula to the problem areas, and then wipe it all off with that whiteboard eraser that you were tempted to throw away.  (A Kleenex or paper towel will also work, of course.)  It works like magic on residual marks left by either smelly or low-odor markers.

I’ve heard that a smelly dry-erase marker will even clean off marks made by a permanent marker, but I’ve never tried it…

Malware: Be afraid. Be very afraid…

Sunday, July 13th, 2008

Yesterday, I Googled my own blog and found a link to an unfamiliar site.  I clinked on the link and…

All of a sudden, my computer starts downloading a *pile* of random crap.  I click the “cancel” button, but the stuff keeps pouring onto my hard drive.

Moments later, a popup window announces that my computer is infected, and provides a link to a website to purchase something called “Antivirus XP 2008.”  The window starts popping up every couple of minutes.

Here’s the really scary part — all the crap loaded onto my computer manages to do the following:

  1. It changed my Desktop to a hideous bright blue with a yellow rectangle in the middle telling me that my computer is infected.
  2. It changed my Internet Explorer home page to their page.
  3. It added links to my Quick Start menu and Desktop.
  4. It disabled Task Manager — so I can’t stop the stupid thing from running.
  5. It disabled Registry Edit — so I can’t open the registry to try to fix the problem.
  6. It removed the “Run” button from the Start Menu, so I can’t run any DOS commands.
  7. It removed the “Control Panel” button from the Start Menu, so I can’t change my PC’s settings.
  8. It removed the “Search” button from the Start Menu, so I can’t look for their files to delete them.
  9. It changed the “My Computer” directory to hide the C: drive, so I can’t find their files and delete them.
  10. It wiped out all earlier System Restore points so that System Restore is now useless.

There were probably other things that I didn’t even notice.

The first rule when this kind of thing happens is:  DON’T PANIC.  Don’t start deleting stuff.  Don’t try to edit your registry.  If you have HijackThis, you can print out a report, but don’t start zapping random-looking files.  It is surprisingly easy to brick your computer once you start messing with system files.

Leave the infected computer alone.  Go to another computer and start Googling.  (What?  You *still* only have one computer?  Seriously, dude, go to www.dfsdirectsales.com, eBay, or wherever, and buy a cheap second computer.  It is so worth it.)

My Googling efforts uncovered the following:

  1. Antivirus XP 2008 is the latest in a long line of malware that is designed to extort money from PC users desperate to get rid of all of the annoying pop-ups.
  2. AVXP comes from the former Soviet Union — be *very* careful if you ever see any URL that ends in .su.
  3. Although it is unbelievably obnoxious, AVXP doesn’t seem to harm any of the data or software on your computer.
  4. I gather that if you pay their blood money, the software they sell you will solve the problem (but will undoubtedly put you on some sort of “sucker” list on which you will remain for the rest of time).
  5. My understanding is that AVXP only detects and removes fake security threats that AVXP itself placed onto your computer during the initial attack.  Therefore, as I understand it, there is no reason to get the software, other than to get rid of the problem that they themselves created.
  6. Other commercial anti-malware products may also work.  I suspect, but have no proof, that some of those commercial products (which usually go for something like $29.95 per license) are in cahoots with AVXP.
  7. However, you can get rid of AVXP for free (really, for free) – www.malwarebytes.org has a free anti-malware program that, much to my intense astonishment, joy, and gratitude, solved the problem completely.
  8. Also free: SUPERAntispyware (www.superantispyware.com).  One site recommended running the free version of this product in Safe Mode after you get rid of AVXP.  (To enter Safe Mode, reboot your PC while pressing F8.)
  9. And: BitDefender (http://www.bitdefender.com/scan8/ie.html).  They have a 100% free scan you can run at the end to make sure you’ve gotten rid of any last remnants of AVXP.
  10. I urge you to use Google (or whatever search engine you prefer) to double-check and confirm everything in this post before trying to apply any of it.

Good luck!

Geek Tip: How to Organize a Hard Drive (and a Life)

Wednesday, June 25th, 2008

Rule 1:  Don’t buy anything.

Rule 2:  Don’t do anything dramatic.

Rule 3:  Start by organizing small stuff that annoys you on a daily basis.

Rule 4:  Don’t bother organizing stuff that you’re never going to need.  (You can keep it — but just leave it alone unless it’s in the way.)

Rule 5:  Instead of trying to pave over the Atlantic Ocean, aim to create islands of order in a sea of apparent chaos.

Rule 6:  Form follows function.

Rule 7:  If it ain’t broke, don’t fix it.  (Perhaps this should be Rule 1.)

Geek Tip: Partitioning Your Hard Drive

The only people who should partition their hard drives are the ones who can’t be talked out of it.

Geek Tip: Car Cell Phone Chargers Suck

Monday, June 23rd, 2008

You’re driving along, your cell phone dies.  No problem — you have one of those phone chargers that plugs into the cigarette lighter.  You hook it up and…

Nothing happens.

What they don’t tell you when you buy the g.d. thing is that a lot of car chargers don’t work if the cell phone’s battery is completely dead.

Geek tip:  Don’t waste your money buying a charger that plugs into your cigarette lighter.  Instead, get something called an “inverter,” which converts the output of your cigarette lighter socket into 120V AC.  When you need to charge your cell phone (laptop, pda, etc.), just plug the regular charger cord (the one you plug into a wall socket) into the inverter. 

You can find a decent one on the internet for $30-$40 bucks (and it will be good for *all* your chargeable gear, as well as any small corded electrical appliances you may want to use while the car is running).

Warning — when it’s plugged in, you should treat the inverter just like you would treat a live extension cord from a wall socket.

Also, you may find that the car has to be moving at a reasonable clip in order for the inverter to work at full capacity.

Tech Tips: The Dreaded Blinking Yellow Light

Monday, June 16th, 2008

My Dell Optiplex PC wouldn’t start, and the on/off button was blinking yellow.

It turns out that this was Blinky, the dreaded blinking yellow light (the power supply equivalent of Blooey, the dreaded Windows blue screen of death).

Of course, I didn’t have a current backup for the bricked computer, and the warranty had expired.

I found one quick fix on the internet: checking all of the USB ports to make sure that none of them had messed-up contacts that might be causing a short circuit. No such luck — my USB ports all looked fine.

I considered trying to install a replacement power supply into my PC, but I found a bunch of posts on the internet from people who had tried replacing the power supply and/or the motherboard (!) without success.

I decided, for the time being, to abandon the Brick, and to try to salvage my data by installing the Brick’s hard drive into another computer.  (What?  You don’t have a second computer on your desk?  What kind of Geek are you?)  Sad to say, the hard drive from the Brick was a SATA drive.  The second computer (an older model) only had IDE connectors.

No problem.  I went to the local build-it-yourself computer store and bought a hard drive enclosure (sometimes called a “shell”) for $50.  (You can undoubtedly find one for less, but I was in a hurry.)

I installed the Brick’s hard drive into the shell, and then plugged the shell into the second computer’s USB 2.0 port.  I was back in business in under 30 minutes.   If you look on the internet, you can find web pages explaining how to run email and other apps from an external drive.

I then ordered a used, off-lease computer at www.dfsdirectsales.com.  Assuming I read the spec sheets correctly, I should be able to cannibalize the Brick for stuff like RAM, etc., and install it into the new computer.  Total price, including shipping:  $278.00.  (If I had been more confident about being able to salvage parts from the Brick, I could have gotten out for $50+ less.)

So, all in all, Blinky only cost me about 90 minutes of downtime, and $328.  Plus, I get a new computer!  (Well, it’s new to *me*, anyway…)

Followup (March 19, 2011): It turns out that Dell Optiplex computers of a certain vintage have a known issue with their motherboard capacitors. If you’re a brave soul with a soldering gun, you can try replacing the capacitors — there are a couple of webpages out there that show you what you have to do. You can also try buying a replacement motherboard on eBay. As for me, the Brick is sitting in my garage, missing various components that were cannibalized for other systems.
