Types of Ports

In computer hardware, a port serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors making up the outlet provide a signal transfer between devices.

Serial Port

send and receive one bit at a time via a single wire pair (Ground and +/-).

Parallel port

send multiple bits at the same time over several sets of wires.

USB Port

Can connect up to 127 different peripherals

FireWire Port

Previously known as IEEE 1394 port. Can connect up to 63 devices.


is a device attached to a host computer, but not part of it, and is more or less dependent on the host. It expands the host's capabilities, but does not form part of the core computer architecture.

Examples are Digital Cameras, Image Scanners, Webcams, Microphones, Loudspeakers, Tape drives, and Computer Printers.

Speed Up Your Computer

If you want to improve the speed of your computer, that’s great. However, above all, do no harm and beyond the scope of this Windows forum, ask for help from those you know if you get in over your head. Remember: you have time. You can stop most processes I discuss without causing harm. Caution and common sense go a long way when working with computers; problems are often much easier to fix than they appear.

1. Make Sure Your Hardware is Sufficient

Above and beyond everything you can do with software to optimize the function of your computer, making sure you have the proper hardware to support Windows is critical.

2. Clean Your Desktop

Is your Windows Desktop dotted with files? Have you noticed that your computer has been running slower and slower? Do you see the hard drive light often flashing while you wait for the computer to respond to an action? There are steps you can take to fix it. Read this article.

3. Scan Your Windows System for Errors

An operating system is a collection of files that perform different functions. It is possible, over time, that one or more of these system files has changed or become corrupted. If this happens, the speed of your system may decrease. By using a utility called “System File Checking”, it will inspect these files and correct any problem it finds.

4. Scan for Viruses, Spyware and Adware

Every Windows computer is vulnerable to viruses. Viruses are nasty little programs that cause both major and minor problems for users.

Spyware and Adware are programs created by companies to find out more information about customers, so they can better market products to them. Usually these programs are not created for malicious purposes. Spyware and Adware can load into computer memory and slow it down.

Periodically scanning and removal of Viruses, Spyware and Adware is a great way to improve computer performance.

5. Uninstall Unused Programs

Over time, you may have accumulated programs on your computer that you do not use. When a program is installed, it creates connections between the program and the operating system. Even if you don’t use these programs, they can slow down your system. If you have the original program’s installation disk or file, removing programs will free up space on your computer and may speed up your system's performance.

6. Adjust Visual Effects for Better Performance

Windows provides a number of interesting visual effects including animated windows and fading menus. If you do not have enough operating memory (see above number 1), these effects can slow down your computer. Adjusting or reducing visual effects can make a difference.

To speed up Vista computers in particular you can disable features and function that are not used. For more information, read "How to Speed Up Windows Vista."

7. Don’t Automatically Start Programs

Programs use operating memory (RAM, also called system resources). Unless you always use these programs, you can keep them from loading at Windows startup and speed both the booting of your computer and its performance.

8. Defragment Your Hard Drive (After you have tried everything else)

The more information and programs you have on your computer, the more it is likely that Windows has placed parts of the same file in different locations on your hard drive. It may do this for hundreds of files and programs, depending on how much space is available. Defragmenting the hard drive places all information for each file in one place. The result can be a faster computer experience.

Important Note: Before you even try this, backup all your work onto a different computer, hard drive, CD or disk. Also, you should only do this if you have a reliable source of power for your computer. Doing this when there is a brown out or power problem in the neighborhood, is not a good idea. If a computer turns off while it is defragmenting a drive, it will create more problems than not defragmenting it in the first place.

9. Reinstall the Operating System and Programs

If you have done all the above steps and your computer does not become more responsive, you might consider reinstalling the operating system and programs. This is a scorched earth option - basically you backup all your data and user settings, wipe your hard drive clean and re-install the operating system with your original disks. Next, install all your favorite programs and restore all your data and user settings.

The nice thing about doing this is that you essentially have a new computer, free of years worth of software and registry changes, additions and errors that can turn a fast rabbit of a Windows computer into a slow turtle. The bad thing about this choice is that it takes time and planning to do it correctly. If your PC is 3 to 4 years old and continues to run slower than it did when you purchased it, this might be the only action that will make a significant difference.

NTLDR is Missing


NTLDR is Missing.

Related errors

Below are the full error messages that may be seen when the computer is booting.

NTLDR is Missing
Press any key to restart

Boot: Couldn't find NTLDR
Please insert another disk

NTLDR is missing
Press Ctrl Alt Del to Restart


1. Computer is booting from a non-bootable source.
2. Computer hard disk drive is not properly setup in BIOS.
3. Corrupt NTLDR and NTDETECT.COM file.
4. Misconfiguration with the boot.ini file.
5. Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32.
6. New hard disk drive being added.
7. Corrupt boot sector / master boot record.
8. Seriously corrupted version of Windows 2000 or Windows XP.
9. Loose or Faulty IDE/EIDE hard disk drive cable.
10. Failing to enable USB keyboard support in the BIOS.


Windows XP users

1. Insert the Windows XP bootable CD into the computer.
2. When prompted to press any key to boot from the CD, press any key.
3. Once in the Windows XP setup menu press the "R" key to repair Windows.
4. Log into your Windows installation by pressing the "1" key and pressing enter.
5. You will then be prompted for your administrator password, enter that password.
6. Copy the below two files to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer.

copy e:\i386\ntldr c:\
copy e:\i386\ c:\
7. Once both of these files have been successfully copied, remove the CD from the computer and reboot.

Error Messages on Start Up

Error messages like nwlink.vxd missing or damaged - press any key to continue may lead you through several messages before starting Windows. It is certainly an inconvenience to keep pressing 8 to 10 keys each time you want to start Windows.

This is caused by the incorrect deletion of programs. When removing a program from a computer you need to use the Add/Remove Software in the Control Panel to actually un-install it rather than delete it.
Just deleting a program is likely to give you these error messages.

Solution: Just don't do it again. (The problem can be solved by editing the ini files and the registry but that as that is a risky proposition you may just want to put up with the inconvenience till you next format your hard disk and re-install Windows).

Modem cuts off frequently

Modems cannot handle the beep on BT's call waiting facility. If you have call waiting on your line you will need to disable it before using the modem.

Fuzzy image on monitor

Ensure that your speakers are not too close to the monitor and that there is no other source of interference, especially from TVs, radios, microwaves, dishwashers and washing machines.

-Monitors are sensitive to electro magnetic interference.

-Mobile phones are frequently the cause of this problem.

Computer seems to start up as normal but nothing appears on screen

As obvious as this may sound it is probably a cable not attached correctly, or the monitor power button being turned off. Please unplug all the cables and replace them carefully.


The possible reason is that your graphics card is defective and have it replaced.

No sound from speakers

Please check at the back of the computer. Some computers may have speaker connections on both the soundcard and modem. You will need to plug the single stereo speaker plug into the socket on the soundcard usually marked Audio Out (or in some cases Speaker)


You probably did not install the audio driver.
Please install your audio driver and after installing it restart the system.
