PC Won't Boot Past Windows

FIRST: If your Operating System is Windows Millennium,turn on the computer and immediately press and hold down the CTRL key. Once the startup options appear, release the CTRL key. Select Safe Mode and press Enter. You are now in Windows limited version. If you know what caused your computer not to boot, you can now either change or delete that program.
SECOND: Repair your Registry by selecting Start,Run and typing "scanregw/fix" and press enter. This will fix any damage done to the Registry. You can also restore your registry which replaces your current registry with an earlier copy that was backed up by your computer. Click on Start,Run and type "scanregw/restore" and press Enter.
To repair your Windows 98 Registry,hold down the CTRL key as you start the PC and select "Command Prompt Only".Type "scanreg/fix" and press Enter and "scanreg/restore" to restore a previously saved copy of the Registry.
If you have Windows XP,press F8 after rebooting the PC should Windows freeze while booting up. You can select "Last Known Good Configuration" after rebooting to allow the computer to boot the last backed up files. And you can choose "Safe Mode" to remove any files you know caused the operating system to hang up. Be prepared when your operating fails to boot. It would be a great idea to go over this article a few times and print it. Make yourself s notebook and place this and all related articles there.
If your computer fails to boot or begins to become unstable,you can refer to these articles to make corrections that are needed. Learn these steps from your television set with the PC Super Pack.
Be sure to note any changes you make to your Registry and if you're not sure,its best to find a friend that's pc savvy first. Above all,be certain you back up your registry before making any changes and know how to restore as well.

Keep Your Antivirus Up to Date and Scan Your Disks

Bring your antivirus program up to date and regularly do a full virus scan of your computer. Check your antivirus program as it will tell you when the last full scan was done. You may be surprised to see it is not what you thought, but was done months ago.
If you don't have an up to date antivirus program, and don't want to pay for a new one, there are several high quality free ones available to the private consumer.
They are: AVG, Antivr, avast, PC Tools antivirus, Comodo antivirus and the open source Clam AV.
Also look into a new different kind of antivirus program ThreatFire which you can use to supplement your other antivirus. ThreatFire doesn't look for the fingerprints or DNA of known viruses. Instead it looks for suspicious behavior like key logging.
Also try the no longer free WinHki Anti-Virus, which acts as a supplement to normal Antivirus program like above. WinHki calculates the checksums ( a mathematical calculation extremely difficult to fool) of your files on initialization.
After that, whenever a virus changes a file it will be flagged by WinHki because the
check sum will change.

How To Add Random Access Memory To Speed Up Your Desktop

When you purchase a computer, it will come with an adequate amount of RAM or Random Access Memory to run the operating system and all software that is installed.
However,as you install more software, your PC will begin to slowdown. The amount of RAM you need depends on your operating system on all applications you may be running on your computer at any one time.
           Installing memory is one of the easiest tasks. Take the time to first be sure you have the right RAM for your computer. If you're in doubt take it back to the place of purchase and be sure you have the right RAM.
          After being certain you have the right RAM, you're ready to open the system unit and begin. But first, you need to remove static electricity. Watch this short video about installing RAM Memory on the motherboard.
          Remove static electricity before you remove the new memory from its protective wrap. Its best to purchase a Wrist Strap if you plan on working in your PC often. But if not, you can simply touch a door knob or your computer's metal case to remove the static electricity. To install your new Ram, perform the following.
        Check to see if you have ample light. You may want to have a container to place small screws in. The system unit cover may have small screws and you don't want to lose them.
         After you have plenty of work space and ample lighting, prepare your mind as well. Make this and every other adventure of working on your computer educational and fun.
         Take the time to study the actual components inside your computer. You'll be glad you did should something go wrong. Follow these steps to install your drive.
  • First: Turn off your computer and unplug all peripherals. Take notice of how you unplug
or disconnect any devices. Locate the RAM on the motherboard.
  • Second: Remove the side panel of the tower system or the cover if you have a 
desktop. Place the panel in a safe place well out of the way.
  • Third:Before touching anything inside the system unit, remove electrical static charge
from your body by touching a door knob or any unpainted metal surface.
  • Fourth: Remove the new memory from its protective wrapping and locate the sockets
or memory banks to install the new memory chips.
  • Fifth: Notice the type of retaining clips that hold the chips in place. Remove any old
chips you intend to move.
Now to be sure you won't damage the chips, ground yourself again to remove any
remaining static electricity.
  • Sixth: Pull the retaining clip open and carefully slide the RAM Chips in their memory
banks. Push the clips back over the new memory chips.
  • Seventh: Check and double check the firmness of the chips by gently trying to move
the from side to side. Take a good long look at the chips for anything that looks unusual.
  • Eighth:Replace the system unit cover and reconnect all peripherals.Reboot the 
 computer and the operating system should recognize your new or added memory without  
 any problem.
          Its that easy when it comes to installing new or more memory. Read your computer's
manual first to find out what type of ram memory you have and what is needed for upgrades.
         Take time to Visit the Kingston Memory site above and use their memory configuration to find out the memory you need to upgrade your computer.
      And go ahead and enjoy the faster speed you should experience once your new memory is installed. Don't forget to run scan disk, defragment and disk cleanup to clean your hard drive of extra space.

HTML Tutorial(version 5.0):Part-1

This tutorial is designed to teach you some the basics of HyperText Markup Language (HTML),with an emphasis on transforming a word-processing document into a simple Web page.
You can get the most recent version of this tutorial from the CAT website:
http://cat.xula.edu/tutorials/
Contents
This tutorial will guide you through the following steps:
  • Retrieving the necessary materials from the Web
  • Copying text from a word-processing document and pasting it into an HTML template 
  • Marking block elements and validating your work
  • Marking inline elements and validating your work
  • Using Netscape Composer
  • Using Word's "Save as HTML" feature.
  • Uploading your files to the Web server
Prerequisites:
This tutorial assumes a level of competency with basic computing tasks and concepts. You should
understand the following terms:
  • Files
  • Folders
  • File hierarchy
  • The desktop
  • The Finder (Mac only)
Conventions
Actions that you need to perform are bulleted, like this:
  • Open the file.
Menu commands look like this: File > Open. This means choose the Open option from the File menu. Sometimes, for the sake of brevity, common menu items may be referred to simply as Save or Open. The same style is used for other user interface elements, such as key you're supposed to press and buttons you're supposed to click, i.e. "Click the OK button."
HTML code and URLs look like this:
<BODY BGCOLOR="white">
Names of files and folders, as well as text that you are supposed to type, are rendered in italics.
Before You Begin:
  • Look over the "Hypertext Markup Procedure" and "30-Odd Safe HTML Elements" quick reference sheets. Re-examine the handouts on "Anatomy of a Web Page" and the"Container Model."
  • Read the following information about filename extensions
About File name Extensions
  • Some operating systems use filename extensions to identify different types of files. For example, a file named document.htm or document.html is marked as a Web page. A file named document.gif is marked as a particular type of image file, while document.jpg indicates an image file of another format. A Microsoft Word document might be named document.doc, whereas a plain text file would most likely be named something like document.txt.Web servers, which may run on a number of different operating systems, use file name extensions to identify file types.
    The Microsoft Disk Operating System (MS-DOS) uses filename extensions. Windows uses them too, since it is built "on top of" MS-DOS. Windows is often configured to hide filename extensions, so that you may no t be aware of them. (But see below for the remedy.)
    The Mac OS doesn't use filename extensions. A very different system is employed to identify different file types, so that a file named document could be almost anything -- text, graphics, audio, video, whatever. Mac users who want to publish on the Web or share files with Windows users need to be aware of filename extensions and start using them correctly.
    Examples of Common File name Extension Problems
    • You find a file named document.html.txt. Which is it — plain text or hypertext?
    • You create a web page that is supposed to display an image. The image file is named picture.jpg but you mistakenly set the SRC attribute of the IMG tag to point to picture.gif. The image does not appear.
    • You're a Windows user. A Mac user sends you e-mail with a Word document attached. It is named Final Report. You can't open it. Because Final Report has no filename extension, the Windows operating system can't identify it as a Word file. If the Mac user had named the file Final Report.doc, this would not have occurred. Also note that it's good practice to avoid spaces and case variations in filenames if you plan to share them over the Web, so an even better name would be final_report.doc, final-report.doc or finalreport.doc.
    Windows Only: Configure Your System:
    Follow these instructions to make Windows display filename extensions at all times. This is highly recommended for aspiring Web authors, because it reduces opportunities for confusion.
    • WinXP: From the Start menu, choose Control Panel, then double-click on Folder Options. (In older versions of Windows, Open any folder or drive. From the View menu, choose Options or Folder Options.)
    • A dialog box should appear. Click the View tab.
    • Look for an option that says "Hide file extensions for known file types" or "Hide MS-DOS file extensions for file types that are registered." Make sure this item is not checked.
    • Click the button marked OK.

How to Update Your BIOS

Your computer's BIOS (Basic Input/Output System) is the first software your PC loads. It sets the stage for your operating system, so to speak, by finding all your PC's various hardware components and letting the operating system know it can use them.
As with any software, your computer or motherboard manufacturer periodically updates the BIOS to fix bugs, add compatibility with new devices, improve caching functions, and make several other hardware tweaks that can speed up your boot time and fix annoying issues. These updates are available at the manufacturer's site. But if you make a mistake in the update process, you risk rendering your PC unbootable. Here's how to make sure your BIOS update goes without a hitch.
  • Identify your current BIOS version: The easiest way to find your BIOS version is to open up the System Information app in Windows--just type msinfo32 into the search bar (for Windows 7/Vista) or the Run box (XP), and click System Summary; your BIOS version should now show up on the right under your processor speed. Record your version number (and the date that appears afterwards, if applicable).check your BIOS version, without restarting your PC, by using msinfo32.exe (as described in the text)
  • Check your PC/motherboard manufacturer's Website for BIOS updates: Those of you who assembled your PC yourself will need to look for BIOS updates from your motherboard manufacturer's Website. If you don't remember your motherboard's model number, you can look it up without opening up the case by downloading and running CPU-Z and clicking on the Mainboard tab. Most PC manufacturers handle BIOS updates based on your specific line and model, so head over to your manufacturer's support page and check its listings for your PC, because if you download and install a BIOS intended for a different model, your PC probably won't work (although most BIOS updaters are smart enough to notice if you try to install them on the wrong hardware). If there is a BIOS update file available, grab it--along with any documentation it comes with, because often warnings and specific instructions are contained in the Read Me docs. 
  • Read the included documentation:  
  • The BIOS updater's Read Me file will most likely include a list of fixes and new functions, often to support new hardware. Updating the BIOS for my Lenovo Thinkpad T500, for example, added support for a new AC adapter and a 1600-by-900-pixel screen resolution on an external monitor; the update also fixed fan speed and Webcam issues that could not have been handled by updating Windows or my specific device driver software.
    More important, however, were these notes in the Read Me file: If I was running Vista on my T500, I'd need to make sure that I had a certain patch installed; and if my T500 had a certain graphics card, I would need to update its drivers above a certain version before updating my BIOS. Read and reread your docs, or you might make your PC unable to boot without even knowing why. 
  • Update your BIOS
    Most newer PCs have a fairly easy BIOS update procedure: Just download the .exe file from your PC manufacturer's Website, quit all open programs, run the .exe, and let it handle the patch; then reboot. If your PC suddenly shuts down in the middle of the BIOS update, you won't be able to boot up, so make sure you're not running off a laptop battery. Ideally, you're plugged into an uninterrupted power supply (UPS), especially if you're in an area prone to blackouts.
    Older PCs, however, might require you to set up your own bootable disk to update the BIOS yourself. You might still be able to download an app that configures a USB thumb drive, blank CD/DVD, or even a floppy disk so that you can boot off of it to update the BIOS, or an ISO image file that can be used in your disc-burning app of choice (if you don't have such an app, try ISO Recorder for Windows XP or the version for Windows 7/Vista) to create a BIOS update CD.
    Other systems will have you copy a few files to your bootable disk, restart, and open up the BIOS during start up (typically by pressing a specified key for setup options), and change the boot order so your system looks for a bootable USB drive or CD before loading the OS from your hard drive.
