Install Microsoft Windows XP

Below are the steps required to installing the standard version of Microsoft Windows XP. It is important to realize that some computer manufacturers have their own proprietary install of Windows XP on a Recovery or Restore disc or may have a hidden partition that installs Windows XP. Therefore the steps below may not all apply to how Windows XP is installed on your computer. If the steps below do not apply it is recommended you contact your computer manufacturer for additional help, Computer Hope will not know how to install Windows using your manufacturers CD.
  1. If you're still able to get into Windows before following the checklist of things to consider before erasing the computer and starting over.
  2. The standard Microsoft Windows XP CD is bootable. Therefore start by placing the Windows XP CD in your computer and reboot.
  3. As computer boots a prompt to press Any key to boot from CD should be seen. When seen immediately press any key. If you do not get this prompt or are unable to boot from the disc run through the booting from a CD troubleshooting steps.
  4. When the Windows XP setup menu appears press ENTER to continue the setup.
  5. Next, the Windows XP licensing agreement will be shown, if you agree to this agreement press F8.
  6. Next, Windows gives you the option to repair Windows XP or to install a fresh copy if Windows XP is already installed on the computer. If you're wanting to install a new copy of Windows XP press ESC.
  7. Next, the partition setup will appear, it is recommended that if a partition already exists and you do not plan on having multiple operating systems on the computer that you delete the existing partition before continuing the setup.

5 Common problems of Hard Disk

Hard Drive Running Slow
This is probably the most common problem people have with their hard drives. Unfortunately, that is not a hard drive problem but an operating system (OS) issue. Simply defragmenting your computer will fix this situation.


Hard Drive Won't SpinIf your hard drive won't spin,
This is possibly because of a power differential. Either there is a problem with the electrical cables or your hard drive simply is not getting enough power.

Hard Drive Not RecognizedIf your computer won't recognize your hard drive, you may have to play with the BIOS. Ensure that your hard drive and disc drive BIOS are enabled.

C Drive Not Recognized
As with your hard drive not being recognized, if your computer will not recognize your hard drive as the primary C drive, check your BIOS and run any BIOS discs that came with the hard drive.

Frequent Drive Failure
If your hard drive fails on you often, you may have a simple case of dusty computer. A thorough cleaning should help with this issue.

5 Fixing a Hard Drive Problem

Hard Drive Failure 101

There are a few signs that can mean a hard drive failure is coming. A clicking noise coming from a computer is one of the most common and clear signs that a drive is on its last legs. If you hear your hard drive clicking, chances are it's time to get a new one - before it quits. Another common error is programs freezing. While blue screens can often indicate RAM problems, freezing programs often indicate that the hard drive has an error on it. These problems are usually cheaper - but not always easy - to fix.

So if you think your hard drive has a problem, what do you do? 

Fixing a Hard Drive Problem

Back It Up
Regardless of hardware or software failure, it's always good to back up your data. The simplest solution is to use a cloud-hosted solution, although what option you use will depend on how much data you need to save. You don't need to copy everything off your hard drive, but include any irreplaceable files. If you have fewer than 5 gigabytes of data, consider using Google Drive. If, on the other hand, you have a lot of photos and videos, consider a paid data backup option like Crashplan, or a physical backup drive like the Seagate GoFlex, which you can use for automatic backups. (Get more tips in Cloud Vs. Local Backup: Which One Do You Need?)

Check Your Disk for ErrorsThe easiest way to see what's wrong with your disk is simply to ask it. If you're running Windows XP, Vista, Windows 7, or Windows 8, open "My Computer," right-click on the drive you want to test (probably c:), then click "Properties," the "Tools" tab, and the "Check Now" button. If you have a pretty good feeling it's going to find a few problems, check both of the boxes. They'll fix any errors that can be repaired. If you're lucky, this will solve your error problems.

Replace the DriveThere's a chance your hard drive will be almost kaput and the diagnostic tool will tell you so. If the diagnostic tool crashes, replace the hard drive as soon as possible. If you do this, make sure to deactivate any software like Office 365 or Adobe programs. You can then install Windows on a new hard drive and restore your files from backup.

Clone the DriveIf you're feeling a bit more ambitious and don't want to start from scratch, you can make an "image" of your drive and put it on your new hard drive. Daemon Tools can help you do this, and you'll find instructions on how to restore the image here. Be warned that this is a technical process, and if your hard drive errors were due to viruses, you run the risk of transmitting the viruses to the new computer. If you want to do this but feel completely out of your league, make sure to contact a computer repair professional.

Hard drives cause problems more often than you'd think, and they can render your computer virtually inoperable. Fortunately, the fix is often fairly simple. No matter what you do, remember to back up your hard drive regularly. That way if it does fail, you'll still be able to retrieve your most important data.

Hard disk Problem

Hard drive serial killers are the destructive forces that threaten to destroy your hard drive. The six worst hard drive destroyers are simpler than you might think.

Serial Killer #1: Heat: The primary cause of hard drive failures is hardware overheating. Inadequate ventilation and cooling in and around your computer hardware can cause severe damage to the equipment. Overworked hardware with little or no downtime and smoke or fire damage can wreak havoc on a system.

Serial Killer #2: Physical damage to your computer: Any type of physical force, such as bumping, jarring, or dropping your computer may lead to physical damage to the hard drive. If your computer is in use at the time of the impact, the read/write heads may touch or gouge the disks, causing damage to the platter’s magnetic surfaces where the data is embedded. This is known as a head crash, and the damage can be significant. Even if your computer is powered down, the likelihood of jarring your computer’s components is still present.

Serial Killer #3: Power Surges: A power surge can be caused by lightning strikes, interference with power lines, or by any event which causes the flow of energy to be interrupted and then restarted. Power surges can result in data loss when the read/write heads fail to function properly, and in the worst case, a complete computer crash.

Serial Killer #4: Water Damage: Moisture caused by flooding or even by spilling a liquid onto your computer is almost assuredly bad news. The casing that holds the hard disk drive is not designed to be a barrier against water penetration. Water will have damaging effects on a computer’s electronic parts and disk components, possibly even causing unwanted electrical currents which can further damage your computer.

Serial Killer #5
: Corrupted files: Improperly closing a program, turning of your computer before closing files, and installing new software can cause files to become corrupted. Power failures and accidental computer shut downs can contribute to corrupted files, and causing damage to the hard drive.

Serial Killer #6: Human error: The functions of the hard drive can be impaired by human tampering with the system files. Accidental deletion of files imperative to the disk drive is not uncommon. Improper installation and removal of files from your computer can cause the hard disk to malfunction. Activities conducted during a forensic investigation of a computer may also compromise the hard drive.

Study Tricks - 1

Reading, writing, arithmetic. They're the core of the grade-school curriculum - but often the bane of a child with attention deficit disorder (ADD ADHD). Your child's teacher may not have the patience or expertise to offer your child tips to master these subjects in ways that work best for her.
That's where you come in. Help your child use these creative learning tricks, and watch the three R's soar.

Reading

  • Follow with a finger. Encourage your child to read with a guide finger. This can help with losing his place, skipping lines, and omitting or repeating words.
  • Stick 'em up. Have your child mark important passages with sticky notes, so she can find them later. Use a symbol for each topic, for example, a smiley face for information about a character, a house for setting, a star for important ideas.
  • Pace read-alouds. Suggest that your child take a short breath at each comma and a regular breath at the end of each sentence. This will improve his reading pace - and comprehension.
  • Find the five W's. Focus on who, what, when, where, why, and how when reading. Help your child track them with a chart.
  • See it. Help your child to visualize a story by seeing it as a movie in her mind. As she reads, the movie should change. This will help her remember characters, facts, and concepts.

Writing

  • Chart it. Have your child verbalize what he will write, then make a flow chart or mind map. Have him write the main topic in a circle in the center of a piece of paper, then write subtopics in other circles and connect them to the main circle with spokes. This will enable him to articulate ideas and link them appropriately, regardless of the order in which they were generated.
  • Use a story organizer. This works for both reading and writing. Your child should make a list that includes characters, setting (time and place), the problem, the goal, the action, and the solution. Fill in the details under each heading.
  • Draw it. Use diagrams or drawings to plot and tell a story.

Math

  • Use games. Here's an example, for multiplying 9s: Lay your hands flat on the table, palms down, and label each finger 1 to 10, from left to right. For 5 x 9, curl your number 5 finger down. The numbers before this break will be tens, those after will be the ones. With four fingers on the left side of the break and five on the right, you have 45. 5 x 9 = 45.
  • Be manipulative. Use blocks, tiles, even playing cards, to work out computations physically.
  • Draw a picture. For example, if the problem is to divide 48 cookies among 12 students, draw a plate for each student, then divide the cookies among the plates. Seeing the problem helps kids who struggle to learn math in traditional ways.
  • See the sign. Have your child highlight the operational sign (+, -, x, ÷) for each problem before working the calculations. This reinforces the type of computation asked for.

How to cheat in Exam Method - 5

Try cramming information last minute. By spending the few minutes before an exam skimming over your notes or studying, you have a shot at being able to do well without cheating.

  1. For essays, try to remember key words. Usually professors or teachers have "key words" that they are looking for in an essay. This means that the actual "fluff" of the essay is less important. If you know the topic or possible topics of an essay question, cram four to five terms you know your professor will be looking for. Instead of having to study everything, you can succeed with less effort.
  2. For math exams, try to memorize formulas. Knowing a formula can be more powerful that spending hours doing practice problems. If you can write down a formula enough to memorize it, then you can spend the test trying to apply those to the problems.
  3. For multiple choice exams, try "chunking" information you know will be on the test. Instead of memorizing a list of words, try breaking it into easier to remember smaller lists. For example, if I am studying for a history test, instead of remembering "Jefferson, Hamilton, Franklin, Washington, Grant, Lincoln, and Lee" break it up into the "4 of the founding fathers: Franklin, Washington, Jefferson and Hamilton" and the "3 civil war leaders: Lee, Lincoln, Grant." By memorizing the number of men to a specific topic, it'll be easier to narrow down who you are missing.
