4 Ways To Destroy Your Computer


I know people don't intentionally try to destroy their computers, but they do it none the less. I have been a computer technician for the majority of my life and I see people unknowingly do the dumbest things to their poor computers daily! So, if you want to join the ranks and demolish your PC without any effort at all, follow along!

1. Don't Use Antivirus Software.

Antivirus software is almost always bundled with Windows computers. Problem is no one has time to run it, update it and if they don't have it, install it. All it takes is one virus to get into your computer to cause huge headaches. In my days I have seen customers have their internet connection disabled by their service provider because their computer was sending tens of thousands of emails due to a mass mailing worm/virus. I have seen people put their fist through monitors (LCD... not the painful glass ones) because they got pop-ups every time they moved their mouse.

In one case I saw a person spend nearly $300 because they got a popup (from a virus) that said the only way to fix this problem is to spend $300 for the fix. It's like digital ransom and unfortunately they unknowingly paid it! So step one in demolishing your computer is to remove your anti-virus software if it's installed and if you're too lazy to do that, simply stop updating it.

2. Install Software Without Knowing Anything About It.

This is my favorite. In the age of spyware and adware you can't trust everything you download on the internet. You may be trying to get a piece of software that lets you convert your music so you can listen to it in your car. When you install it though, you unknowingly install advertising software that is going to annoy you to death with pop-ups. Or in some cases (probably the biggest one I see) is when people install software to download music or movies (no, not legally) and then they are hammered with advertisements or worse, a stolen identity! (Wow, is that instant karma or what?)

Step two is easy. Go and start downloading everything you can without doing some simple research on Google about what you are about to install. Generally you will see a lot of "I hate this software, it has been nothing but a headache" when you search for spyware infested downloads. But we're destroying computers, so we can skip this step.

3. Let It Overheat.

Make absolutely sure that you have your computer in a closed cabinet, or at least have books and junk piled all around it so that no air can flow through it. Be sure to leave it on a carpeted floor so dust can easily make its way into the fans. If you can, leave a window open near the computer so you can get some of that environmental dirt and grime inside, this will ensure it overheats properly. There is no better way to slowly deteriorate the health of your computer than letting it over heat. By no means buy compressed air and blow the dust out every few months, this would be counterproductive to our goal.

4. Ignore All Updates.

Updates to computers are like healthy eating and exercise to humans. Once you let yourself go you are making yourself susceptible to all kinds of fun diseases, ailments and health issues. Strange problems creep up out of nowhere for no reason, everything seems to be going downhill. Updates are simply fixes for glitches and problems that are known to exist. So to ensure those problems can be exploited by a virus, or triggered by a user, be sure to not update anything. It's going to be difficult to destroy your PC if you are allowing updates to be done automatically. So disable automatic updates for your antivirus software, for Windows and any other software you have installed.

So there we have it, four ways to ensure your computer will eventually fail or at least drive you completely insane. If you follow these steps you can expect headaches within two months, and will require professional help within four.

How To Change The Screensaver In Windows Vista


Not long ago many people didn't pay attention to their screensaver until it actually turns on. Now people are using screensavers as photo albums or pictures within a frame. Gone are the days of the default screensavers that come with Windows. They have now been replaced by very high quality and unique screensavers that would make a great addition to any room.

Follow these steps to change your Windows Vista screen saver:

  1. Right click on your desk top
  2. Choose "personalize"
  3. Click on screen saver
  4. A dialog box "screen saver settings" pops up.
  5. Click on that arrow to see a list of screen savers: 3D, Aurora, Blank, Bubbles, Mystify, Photos (our favorite), Ribbons, Windows Energy and Windows Logo.
  6. Next to the pull down arrow is a box called "settings." Not all screen savers can be set. Say you like Aurora. If you click on settings, Windows will say, "this screen saver has no options that you can set." Only a few screen savers can be set like 3D text.
  7. If you choose 3D text and click on settings, another dialog box appears with a slew of options: resolution, size, rotation speed, rotation type (none, spin, sea saw, wobble, tumble). You also get to choose surface style (texture, reflection or custom).
  8. When you click on any of these options, Windows gives you the chance to preview it.

Note: If you downloaded a Vista screensaver from the internet then follow the instructions that accompany the screensaver to install it. Or you can save the .scr file in the C:WindowsSystem32 directory. Once you save the Vista screensaver to that directory it will be available from the standard list of screensavers.

To use your own photo or picture as screen saver:

  1. Go to desk top and right click
  2. Select "personalize" and then click on "screen saver"
  3. Dialog box "screen saver settings" appears
  4. Click on pull down arrow and select "photos"
  5. If you saved your pictures in "My Pictures", click on "settings" and there will be a section in the box where it says "browse"
  6. When you've chosen the photo, click save, and then click OK.

To create your own slideshow for a screensaver:

  1. Go to Windows Photo Gallery
  2. Click the pictures you want to display in the slide show. If you have more than one picture, hold down the CRTL key and click on those photos you want to include
  3. Click the "slide show" button located at the bottom of the photo gallery.
  4. If you don't choose any picture, Windows Vista will play all the photos filed in the picture gallery once you click on "slide show."
  5. Remember that you can control the speed of your slide show.

Now that you've change your screensaver feel free to walk away from your computer and show your unique screensaver to everybody.

Why Bother to Wipe Hard Disk Drives


When you delete a file from your hard disk, it may seem as if it is gone forever. In truth, however, this is not the case. The seemingly permanent process of file deletion actually leaves the file data still on the hard disk. When a file is deleted, it is simply marked 'deleted', and the space that it occupies on the disk is accordingly marked 'ready for use'. Hence, it may be overwritten when more disk space is required, but this is by no means certain, unless the entire hard disk is filled with data.

Now, the actual data that make up the file is still on the hard disk, even after deletion. This makes it available for recovery, usually done using specially designed data recovery programs. MSDOS, in fact, has a built-in UNDELETE command which may recover recently deleted files.

The reason why file deletion is not as thorough as it can be is a simple one; resource management. Actually overwriting every bit of every file that is to be deleted will use more resources than would be practical, for everyday use. And in fact, this simple file deletion is usually sufficient for the basic user's needs.

However, security considerations might necessitate the complete erasure of a given hard disk or collection of hard disks. When reassigning hard disks, for instance, or switching computers around, confidential data might need to be deleted. To lessen the possibility that this data is recovered, a hard disk wipe may be performed. When a hard disk wipe is performed, the entire area of the hard disk is actually overwritten with random data. This means that the data that used to be on the hard disk becomes much harder (practically impossible) to recover after such a process. Almost no traces of the previous data that used to be on the disk is left, making a hard disk wipe a secure improvement upon ordinary file deletion.

The metadata or information on the data that used to be on the hard disk is also wiped clean, since the entire space of the hard disk is overwritten. The randomness of this data used to overwrite depends on the algorithm used to generate it. Some hard disk wipe programs give users the choice to select the algorithm they want the program to use. However this is not as necessary for hard disk wipe programs as it is for file shredder programs, which wipe individual files. This is because when it is the entire hard disk that is wiped, the degree of randomness of the overwriting data is not anymore as important.

Performing a hard disk wipe is often as easy as clicking a few buttons in a specially designed hard disk wipe program. Some programs are set to run automatically when a CD containing the program is placed into the computer containing the hard disk to be wiped. This makes it easier to perform batch wipes on many computers at once, and makes the hard disk wipe a feasible security solution for multiple hard disks.
