as you know , ever or whatever or however you call it your os never makes a suesite ( self killing ) so you need a thirth party to kill you os ...

You need to stop talking garbage and just talk in plain words so that people can understand what you are on to!

How were you trying to format the computer?

using bootable CD of windows XP

Since this is an office computer it may be locked to prevent this from happening. This is the only reason that I am aware of that can cause this to happen. Either there is a BIOS lock or an admin lock preventing you from doing this.
1) for the admin lock you must contact the admin for the unlocking it.

2) I have heard tell of an embedded BIOS from some manufacturers that had a specific rule that would not allow the format or installation from another source except for the disc that was used to install the operating system originally. I have yet to run across one myself but have heard from others concerning this.
If I remember right it took a computer engineer from a certified repair shop to repair this as it takes a special BIOS program to open the lock! This program is only sold to certified manufacturer authorized repair shops and can not be obtained any where else. You can call the manufacturer and ask them about it and I believe that for a fee they will or can do this over the phone and through remote access.

Good Luck!

thankx that was really informative and new stuff for me. but i dont think that is the matter because i have formatted same computer a year back so is there any other issue which causes the problem????

It could be a heating problem.

There is a safety feature within the BIOS that will auto shut down a system if the CPU fan quits working or there is a loss of efficiency....dust build up on the heat sink and fan blades, no air flow through case. Unplugged connection to CPU fan and failure of thermal paste between the CPU and heat sink.

A simple test is to open the case and examine the fans when you boot the system to see that they start up ok. With the case open use a small desk fan to blow cool air into the case and see if there is any improvement.
