Maintaining your Computer

Hardware Maintenance:

1. Clean your computer regularly. Use cotton cloth and other cleaning kits. You can use paintbrush in removing the dusts from the CPU heat sink and the dusts on the motherboard's slots.Make sure that your computer is turned off while cleaning.
2.  Be careful not to bump your computer.
3. If you transport your computer, put it on a carrying case.
4. Keep all liquids away from your computer.
5. Avoid dirty and dusty environment.
6. Make sure that you computer is highly ventilated.
7. Run disc cleanup and defragment tool
8. Shutdown your computer properly.

Software Maintenance:

1. Install all updates required
2. Keep antivirus program updated
3. Do not install different versions of software.
4. Uninstall programs that are not needed.
5. Don't download programs from untrusted internet sites.
6. Be aware of suspicious files from mails.
7. Install only license software. 
8. Shutdown your computer properly.

Back-up files:
       The most important thing you can do as a computer owner is to consistently and reliably back up the data stored on your hard drive. Hardware used to be the most valuable part of a computer but those bits and bytes are now the real investment. 

        Backing up files and removing them from the hard drive frees space for new files on the hard drive. It also protects you from losing important information if the hard drive fails or you accidentally delete files.

       You can use CD's, DVD's, Flash drives, Portable harddisk drive, or even and ordinary hardisk drives in creating file back-ups.

Computer Monitor Troubleshooting

How to Troubleshoot Computer Monitors: 

• Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.
• Check all your power connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable.Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.
• Check for the cables. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose. Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.
• Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark. Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.
• Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.
  • If the new monitor you connected does not show anything either, proceed to Step 6.
  • If the new monitor you connected does show information from your computer, proceed to Step 7.
  Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.
• Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor. Chances are your original monitor is working fine.
• Test your original monitor with a monitor data cable that you know is working. It's possible that the monitor itself is working properly but it can't receive information from the computer because the cable that connects the monitor to the PC is no longer working. Note: If possible, test using the data cable from the monitor that you successfully tested with in Step 5. If not, purchase a replacement monitor data cable to test with. Note: The data cable on some older monitors are permanently connected to the monitor and are not replaceable. In these cases, you'll have to skip this step and proceed to Step 8.
• Replace the monitor.

Super User Account

The superuser account, usually called root, comes reconfigured to facilitate system administration. It is said to "facilitate system administration" it means that this account can access all files and datas of the administrator account even if it is password protected.

This is because the superuser, unlike normal user accounts, can operate without limits, and misuse of the superuser account may result in spectacular disasters.
How to access Super User Accounts: 

• Open command prompt (start > run > cmd > Enter)

• Type this command "at 21:01 /interactive "cmd.exe" then enter." 21:01 is the sample time in which you are now to access the super user account, this time must be set 2-5 minutes advance from the tome of your computer"

• When the system clock reach the time it opens a new command prompt.that looks like bellow.

• Run Task Manager by either pressing CTRL+ALT+DELETE or typing taskmgr at the command prompt. In task manager, go to the processes tab, and kill explorer.exe; your desktop and all open folders should disappear, but the system command prompt should still be there.
•  At the system command prompt, enter in the following: "explorer.exe"
• A new desktop will display and that is the SYSTEM. 

Password on Admin Account

• You accidentally forgot your password.
• Somebody change your password.
• You are attack by a virus.

How to fix this:

1. Insert your original windows xp cd and restrat your computer.
2. Make you that the cd-rom will be your first boot device.
3. When press any key prompted, then just hit any key.
4. When blue screen will display, you are on your way.
5.  Press F8 to agree the license agreement
6. After that, some options will display, then hit enter
7. Your computer will automatically search for the installed Operating System, If your computer finds it hit hit R to repair.
8. Just wait until your computer restarts.
9. When the picture bellow will show , Press Shift +F10
10. When command prompt will display on your screen, type nusrmgr.cpl then Enter. It will allow you to access the User Accounts in the control panel.
11. Now you can add another administrator account on your computer.
12. After making New Administrator account, close it and wait until your computer will be done repairing.
13. After repairing you can use your new admin account to remove the password to the other accounts.

Computer Restarts

Computer will restarts due to this following problems:

• Faulty powers supply
• Defective RAM (Random Access Memory)
• Faulty harddisk drive
• Overheating on CPU
• Overheating on harddisk drive.
• Hardware problems
• Sometimes due to crashes of Operating System
• Virus

Power Supply:

      Loss contact on the sockets from power source can cause restarting. Check all your connections and try it on for another time.If it restarts again then replace you power supply.

Defective RAM:

      Rusty and dusty RAM can cause loss contact from its socket. Remove your memory stick and clean it. Read on this.

Faulty Harddisk:

      Faulty hard disk is one of the most common reasons for abrupt computer restart. Run a hard disk scan to fix this issue. If there are bad-sectors, then replace it.

Overheating on CPU:

      CPU overheats when your cpu fan won't function, maybe your fan won't turn because some wires block it. Most motherboards have CPU temperature setting a their BIOS setup.

Overheating on Harddisk:

      Harddisk overheats when there's no proper ventilation on it's area. When harddisk overheats it won't work as nornal.

Hardware Problems:

      Defective motherboard can also cause restarting. Chances of motherboard to be repair is very low, so you must contact a computer technician to check it and buy a new one.

Crashes of Operating Systems:

       Sometimes a software can also be the culprit behind the computer restart. If you have recently installed new programs and other application you must uninstall it in order to fix your problem. Corrupted boot sector can cause restarting. To fix this click here.

 Virus:
       Some computer viruses are written to reboot your computer without warning. Usually these viruses will make the computer reboot ever 5, 10, 15 or 30 minutes after the computer has booted.

Def. USB Flash Drive

USB Flash Drive
        - a storage device that is smaller to floppy disk. It has a flash memory with Universal Serial Bus interface.This drive is removable and rewritable.A flash disk might become defective if it has bad sectors, in which case a repair is required. Microsoft Windows provides a disk repair utility called "Chkdsk" which checks for errors and will repair any errors it finds.

SYMPTOMS OF DEF. FLASH DRIVE

1. Cannot be detected by your computer.
2. Cannot be formatted.
3. Files inside the cannot be erased.
4. You can't transfer files/data to it.
5. Sometimes it is write protected.
6. The properties will be "0 bytes used space" and "0 bytes free space"
7. Computer cannot recognize the USB flash drive

HOW TO RETRIEVE DATA

   If your flash drive has been formatted unintentionally and you want to retrieve the data you can use some retrieving tools found on internet. There are a lot of retrieving tools so don't have to worry about it..I tried many times retrieving datas from formatted drives. For me I'm using "File Scavenger."

HOW TO REPAIR

1. Click "Start" button, then click on "Computer." A new window will open in which you can establish the drive letter of the defective flash drive. Drive letter "C" is usually the system which Windows is installed. Letter "D" is maybe the CD/DVD drive. For the purpose of this article, lets's assume that letter "E" is the flash drive.

2. Click on  Windows "Start" button and click run. You ca also do this by pressing "windows + R" on your keyboard, the type cmd and hit enter.

3. Type "chkdsk e: /f /r" and press the "Enter" key on your keyboard (in this case, the "e" is the flash drive mentioned in Step 1). This will execute the Chkdsk command line application. Wait for the process to complete. It might take several minutes, depending on the size of your flash drive and the speed at which your computer operates.

4.Restart your computer.

NOTE:
If drive letter "e" is not the correct letter for the flash drive, change the letter in the command, in Step 3, to the correct drive letter.

Def. Harddisk, Cd-Dvd ROM

SYMPTOMS OF DEF. HARDDISK DRIVE:

- The harddisk makes ticking sounds
- The harddisk makes a shrieking or rattling noise
- The harddisk smells burnt
- The harddisk is not recognised any more by the bios
- Your computer won't boot anymore.
- The computer hangs.
- Your harddisk still appears in the bios but cannot be installed by any Operating Systems

If these symptoms occur, your harddisk maybe damage.

WHAT TO DO:

If you can manage your computer to turn it ON for a little while, You must back-up all your important files and save it to your flash drive or any other storage devices. If your computer won't boot-up but your harddisk has been detected on your BIOS then try to make your harddisk slave to the other computer in order to back-up your files.

SYMPTOMS OF DEF. CD-DVD ROM:

- Cannot be detected on BIOS.
- Cannot read your CD's or DVD's
- Wont open or tray will not eject
- Very loud noise
- Works for a while

WHAT TO DO:

If you can manage to disassemble and clean it, then do it.
But if there"s nothing happens just dispose it and buy a new one.

Virus..Trojan..Worm

What is a computer virus?

A computer virus is a small software program that spreads from one computer to another computer and that interferes with computer operation. A computer virus may corrupt or delete data on a computer, use an e-mail program to spread the virus to other computers, or even delete everything on the hard disk.  

Symptoms of a computer virus

If you suspect or confirm that your computer is infected with a computer virus, obtain the current antivirus software. The following are some primary indicators that a computer may be infected:

• The computer runs slower than usual.
• The computer stops responding, or it locks up frequently.
• The computer crashes, and then it restarts every few minutes.
• The computer restarts on its own. Additionally, the computer does not run as usual.
• Applications on the computer do not work correctly.
• Disks or disk drives are inaccessible.
• You cannot print items correctly.
• You see unusual error messages.
• You see distorted menus and dialog boxes.
• There is a double extension on an attachment that you recently opened, such as a .jpg, .vbs, .gif, or .exe. extension.
• An antivirus program is disabled for no reason. Additionally, the antivirus program cannot be restarted.
• An antivirus program cannot be installed on the computer, or the antivirus program will not run.
• New icons appear on the desktop that you did not put there, or the icons are not associated with any recently installed programs.
• Strange sounds or music plays from the speakers unexpectedly.
• A program disappears from the computer even though you did not intentionally remove the program.

Symptoms of worms and trojan horse viruses in e-mail messages

When a computer virus infects e-mail messages or infects other files on a computer, you may notice the following symptoms:

• The infected file may make copies of itself. This behavior may use up all the free space on the hard disk.
• A copy of the infected file may be sent to all the addresses in an e-mail address list.
• The computer virus may reformat the hard disk. This behavior will delete files and programs.
• The computer virus may install hidden programs, such as pirated software. This pirated software may then be distributed and sold from the computer.
• The computer virus may reduce security. This could enable intruders to remotely access the computer or the network.
• You receive an e-mail message that has a strange attachment. When you open the attachment, dialog boxes appear, or a sudden degradation in system performance occurs.
• Someone tells you that they have recently received e-mail messages from you that contained attached files that you did not send. The files that are attached to the e-mail messages have extensions such as .exe, .bat, .scr, and .vbs extensions.

Def. Memory & V-card

SYMPTOMS OF DEF MEMORY

1. System Unit won't boot.
2. Continuous  beeping.
3. Bad graphics/display on screen.
4. Crashes when heavy application is used.
5. Blue screen during installation of Operating System.
6. System Unit will automatically restart.
7. Programs will hang


WHAT TO DO?

      Try to remove the memory stick and clean its connections using a pencil eraser. Clean also the dusts of the memory slots using a vacuum or simply a paint blush will do.If your motherboard have 2 or more memory slots, try to use only 1 memory stick and insert it to the slots one by one. If nothing happens try to use/borrow another memory stick before you buy a new one.

SYMPTOMS OF DEF VIDEO CARD

1. No display on screen.
2. Three short beeps during start-up.
3. Bad graphics display.

WHAT TO DO?

      If your v-card is not on-board, check it if it is not loose (maybe its just a loss contact). Remove your video card and clean its connections using a pencil eraser and re-insert it to its slot. If nothing happens try to insert the video card into another computer, if that computer will display then your slot for the video card is defective and your best option for that is to buy another motherboard. Doing in reverse, try also to insert another video card to your defective unit (make sure that the video card you use is functional) By doing this, you can identify whether your motherboard is defective or your video card.
      If it is on-board, then your best move is to buy an external v-card that will will to your motherboard (maybe its an AGP or a PCI-E).

default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect

Copy the NTLDR and NTDETECT.COM files from another computer using the same operating system. Both of these files are located in the root directory of the primary hard disk drive. For example, C:\NTLDR and C:\NTDETECT.COM should be the locations of these files on many computers.

·        Please keep in mind that these files are hidden system files, if you need additional help with viewing hidden files in Windows please see document CH000516. 

Once these files have been copied to a floppy diskette reboot the computer and copy the NTLDR and NTDETECT.COM files to the root directory of the primary hard disk drive. Below is an example of what commonly should be performed from the A:\> drive.

copy ntldr c:
copy ntdetect.com c:

After the above two files have been copied, remove the floppy diskette and reboot the computer.
