Microsoft Windows

Try this, find another computer and hook the monitor onto it, see if it's blank then.

What to do:

1) If the monitor is not blank then your other computer probably needs a video driver (need help on this? ask another question and I will try to answer you) OR

Your graphics card might be burnt out and you might need to purchase a new one.

2) If the monitor is still blank, try to obtain another vga cable(the blue plug thing), if still blank go buy a new monitor

**Hope this helps would be able to help you better if i know any previous symptoms or was there next to your computer. Good luck!

Update: This answer was written sometime around 2008 and is, at the time of this comment, at least six years out of date. In the computer world, this is a long time in which many things can, and have, happened. The spirit of the answer is roughly correct, but the many details are different.

While I could simply say "yes, Macs are better than PCs," the question is actually difficult to answer since in truth it depends largely both on personal preferences and personal needs. And though I am of the opinion that Macs are significantly superior to PCs and that Mac OS X is significantly better than Microsoft Windows, to state that as fact would be unfair to those with the opposite opinion. Rather, I will attempt to state the differences themselves and let you decide. Nevertheless, I do not want to appaer as a closed minded Mac fanboy simply as a result of my opinion -- in reality, I frequently use XP and have had experience with Windows Vista, not to mention extensive experience with Windows 95, 98 and ME. So onto the answer...

In terms of hardware, Apple Macs (including the various desktop and notebook Macs) tend to use higher quality casings, parts, and hardware than other PC brands. (For example, longer lasting and higher performing Intel processors rather than AMD processors, actual aluminum and steel metal parts rather than painted plastic, and solid glass screens rather than a sheet of gloss plastic.) Webcams, the Apple Remote (for use with things such as the bult in Front Row media center or PowerPoint presentations), internal serge protectors and hard-drive-protecting motion sensors are also commonplace. Macs also frequently make use of magnets rather than clips and other breakable parts (like for securely closing a laptop's monitor or affixing the Apple Remote). Macs are also sleek and are the hardware is nicely integrated with the software.

However, Macs lack of some useful things many PCs have, such as built-in storage card readers or fingerprint security.

Many PC advocates have also made the argument that PCs are cheaper than Macs. However, I would argue that, while inexpensive PCs do exist, they typically lack the high-quality hardware present in Macs. Furthermore, PCs similar to Macs (for example, the Dell XPS laptops or the all-in-one form factor PCs) tend to cost more than Macs and still include slower processors or have other drawbacks.

The prime focus of the argument is whether Mac OS X or Microsoft Windows is better. I will say Mac, citing things such as its resistance to malware, high performance, high reliability, streamlined user interface, and built in tools which can do things such as burn bootable DVDs from ISO images, burn playable DVDs from a VIDEO_TS folder, save any printable document as a PDF, other image conversion and manipulation tools, the bundled iLife software, and the fact that you don't need to activate it when you set it up. Other advantages are the automatic Time Machine backup and the selective restore tool, comprehensive Exposé, Spaces and Widgets time-saving tools.

However, for fairness's sake, I will state the arguments of the PC-supporter. Though the software available form Macs has become very high, there is nevertheless more software made for Windows than Macs. Other arguments for PCs include stating that Macs only seem impervious to malware since all malware is targeted at Windows and that Windows performance is not really worse than that of Mac OS X, two statements I would contest.

Windows' advantages, specifically that of Vista (the most recent version of Microsoft Windows -- one that I would point out has its drawbacks), would include the presence of a Media Center (in the more expensive versions) for use with a TV or for viewing other media on the computer, search-as-you-type in the start menu, and desktop Gadgets. (It should be noted that these new features are also found in Mac.)

So now that I have detailed some differences, it is up to you to decide what you prefer or how either one would best suit your needs. If you are often required to use obscure software and you can't spend more than $500 on a computer, PCs may be the way to go. Or if you are a graphics designer and need a good, quick and reliable for your work, a Mac may be the way to go. Which one is better is up to you.

Generally no.

But if that mac address is currently contacting you, you can usually do a NETSTAT-A and see the mac address translation for each ip address. Then you'll know which IP address to ping.

If you have access to the router (Cisco) that routes for the computer's local

network, then look in the arp table to find the MAC address:

Command > sh arp | inc mac address [0000.0000.0000]

Return will be > : Internet 198.25.15.2 5 0000.0000.0000 ARPA FastEthernet0/0 or

whatever the ip address is and the mac address.

Both Dos and Windows are Operating systems. But, they possess some features which make them differentiate. These features are listed below:

"«Dos is only single tasking while Windows is multitasking.

"«Dos is based on plain interface while Windows is based on Graphical user interface (GUI).

"«Dos is difficult to learn and understand while Windows is easy to learn and understand.

"«Dos is less preferable by users while Windows is more preferable operating system.

"«Limited users can work on dos while in Windows there are many users.

"«We cannot see mouse in Dos while in Windows we can see and use mouse to click on icons or links.

"«Simple text commands are written in Dos while in Windows we operate computer with the help of mouse.

"«In Dos we cannot Play games, watch movies and listen songs while in Windows we can enjoy playing games, watching movies and listening songs.

"«In Dos new hardware cannot work properly while in Windows it can detect and installs software automatically.

"«Application and system software¡¦s did not work properly in Dos while in Windows it runs at a great speed.

"«Dos is not user friendly while Windows operating system is user friendly.

"«Dos performs operations speedily as compared with Windows operating system.

Windows programs, on the other hand, realize that they must share your computer with other Windows programs. Actually, did you know that Windows 3.x itself is a DOS program? What this means is that Windows has control of the computer's hardware, and in turn it shares parts of the computer's resources with Windows programs. The obvious advantage to this arrangement is that you can do several things at once; for example, you could play Beethoven's 5th, start downloading a file from a BBS, then look at your checking account and use a Calculator to check the balance all at the same time. Another advantage is that you can share data between programs; for example, copying a spreadsheet summary into a work processor document.

The important thing here is that many DOS programs will run poorly or not at all in Windows. For example, if you try to run Microsoft System Diagnostics (MSD) while you are in Windows, you will get the message:

You are running Microsoft Windows.

MSD can only report information specified by it's associated Windows Program Information File (.PIF). Therefore information presented may be less accurate or complete than if MSD is run outside of Windows. For more accurate information please exit Windows and run MSD from the MS-DOS prompt.

Some areas may be affected while MSD is run under Windows: Memory values and types will reflect what Windows provides by itself, and through the associated .PIF file; IRQ values may be reported differently; and the visual memory map in Memory, Memory Block Display, and Memory Browser may show different results. Other areas that may be affected include Video, OS Version, Mouse, Disk Drives, and COM Ports.

So how do you know whether a program is made for DOS or Windows? Nearly all Windows programs bear the Microsoft Windows logo Microsoft Windows compatible, while DOS programs do not. If you're still not sure, try running the program from the DOS prompt first. For example, type calc at a DOS prompt; you will get the message:

This program requires Microsoft Windows.

NOTE for Windows 95/98: if you try running a Windows program from the Windows 95/98 command prompt, the computer will simply start Windows (if it isn't already running) and run the program.

A word of warning for Windows users: in the Main group there is an icon called MS-DOS Prompt. This is not the same thing as running in DOS. It will let you run some DOS programs, such as the command prompt or the EDIT program, but it is still running on top of Windows. The proper way to switch from Windows to DOS is to close or exit all of your Windows programs, including Program Manager.

Windows 95/98

One way to switch the computer from Windows to DOS mode is to click on the Start menu, then Shut Down, then choose "Restart the computer in MS-DOS mode". Doing this will close all Windows programs and (mostly) remove Windows itself from memory.

Another way is to adjust the properties of a DOS program. Right-click on your program (or its shortcut), select Properties, open the Program tab, and click on the Advanced button. In the Advanced Program Settings you can set the program to run in MS-DOS mode, and even specify a starting configuration just for that program.

Windows is a GUI (Graphical User Interface).

When working with a CLI, you begin with a blank screen and a command prompt. At the command prompt, you type commands, one at a time, for the computer to process. (i.e. "MKDIR C:\MYDIR" to create a directory called "MYDIR" in the root folder of the C drive) Any programs (text editing, database, etc) are run from the command prompt by directing the computer to the location of the program, and typing the execution command.

Example (Text in italics are commands, other text is command prompt.):

C:\> ''CD PROGRAMS''

C:\PROGRAMS\> ''CD GAMES''

C:\PROGRAMS\GAMES\> ''CD PONG''

C:\PROGRAMS\GAMES\PONG\> ''PONG.EXE''

At this point, PONG would take up the entire screen, leaving you unable to do anything but play the game until you exit the game. After you exit the game, you would be brought back to the prompt:

C:\PROGRAMS\GAMES\PONG\>

On the other hand, a GUI offers much more flexibility by using icons and windows to represent objects and programs. With Windows, you can open several different documents or programs, and easily switch between them. Also, there is the Start Menu, from which you can launch program shortcuts instead of having to wade through the entire file directory to execute your choice of program.

The interrelation is that Windows was originally a program ran to top of DOS. In order to use Windows, you used to need a line in your AUTOEXEC.BAT (a script file that automatically executed on DOS startup) that pointed to the Windows program. Windows versions 3.x - 9x and Me still run on top of DOS. What this means is that those versions of Windows aren't really Operating Systems, because they rely on DOS to process all the programs. All those versions of Windows do is make the programs easier to get to and switch between. Windows NT versions, and the Windows XP/2K line are built on their own system kernel so they are considered true Operating Systems on their own.

On Windows XP, you can get a version of it by pressing Start -> All Progs -> Accessories -> Command Prompt. This is an updated version of the original DOS which would run in fullscreen and be the only thing on the computer. You can get started by typing ''HELP '' to see a list of commands. For info on a particular command type '' /?'' .

1. DOS does not supports GUI, Windows supports.
2. DOS does not supports networking, Windows Supports.
3. DOS is a single user OS, Windows is a multi-user OS.
4. DOS is a single tasking OS, Windows is a multi tasking OS.
5. DOS does not supports threading, Windows Supports.
6. DOS supports maximum 2 GB of partition, Windows supports 2 TB or more.
7. DOS supports FAT 16 file system only, Windows supports FAT 32 and NTFS.
8. There is no server support in DOS, Windows has.
9. DOS is not as stable as Windows.

XP Home

The Home edition of Windows XP---the edition that came with most machines home users bought from the likes of Dell and HP, before Windows Vista---supports only one processor. This means if you want to install more than one processor and you run Windows XP Home, you may need to switch to Professional, or upgrade Windows to a newer version with support for multiple processors.

XP Professional

If you want to use two processors, Windows XP Professional is the way to go. While this advanced program cannot run more than two processors, this is an improvement over Home. Note that, because dual-core processors count as a single processor, you could theoretically have four cores with this license or even eight, if you are willing to buy two quad-core processors.
