Break the system back to only hard drive, cpu, memory, video.  Do you still have a problem?  If so, it is one of those main components.  If not, add parts and pieces back until the problem returns.
adilkhan...

you say that it won't boot up unless you leave it alone for a few minutes... where is it hanging?  Does it stop prior to even seeing the the Windows splash screen or after?

could be bad harddrive.  use windows boot disk and try to run scandisk.  Or you probbaly have delete some of the important start-up files.  good luck...

Welcome to experts-exchange!  We all look forward to the additional input you will have on the variety of topics covered in the community.

Please note that it is common etiquette in some topics areas to always post comments and not answers. There are several reasons behind this thinking, mainly:

- Questions do not become prematurely locked and the collaboration process is not inhibited when the question is indexed as open for proposed solutions.
- The question-asker has the power to select the best solution rather than one that is simply suggested as an answer.

In the future, please refrain from posting an "answer" unless it is the absolute resolution to a post.

Again, welcome to experts-exchange!  Happy to have you onboard!

adilkhan,

difficulty powering up is generally a p/s issue.  an expansion card can cause the system to halt, but i've never seen it cause the system to shut down during a boot process (i guess it's possible, but i've never heard of it happening).

here's what i'd do, were it my system... unplug your power supply from the motherboard, drives & fan.  go out to radio shack, or the like, and pick up an inexpensive DMM (digital multimeter).  you're going to want to check the voltage output at your P8 and P9 connectors.

once you can verify that your p/s is providing the proper voltage without a load, plug in your motherboard... check your voltages again;  now add your master hdd, slave hdd, cd-rom, etc., checking voltage from P8 & P9 after each component is found.

power supply issues can wreak havoc w/a system because there are so many symptoms that can be experienced... but i think you're on the right track here.

hope this helps

Devdas comment did not solved my problem but Increased my headache, I am really Serious about  Data in my Hard Drive. after testing it on other workstation it is for sure Hard Drive is fine. I changed the MotherBoard but my Motherboard is not detecting anything, I am still working on it. if it helped me out then I have to think which expert deserves expert points. if you have any other comments please Post them. Any information on  Jumpers would be helpfull.
If the mobo is not detecting ANYTHING it sounds like you are having mobo or cpu problems.
Have you checked to see if perhaps your Motherboard has a BIOS update that is needed, from the Motherboard Manufacturer's Web site?  It is unclear what you did when you said you changed your Motherboard.  You said you tested the hard drive on another system, if we understand you correctly, and it worked/was fine.  Perhaps if you can tell us the Motherboard type and model and BIOS date/information it'll be a good starting point.

Do you hear any beeps when you try to boot the system, if so how many, etc.  

With so little known at this point, it is tough to give specific guidance, in my humble opinion.

Have you tried only installing, as recommended above, the bare minimum devices to see if the BIOS can detect the hard drives, and basic components?  Is the BIOS configured for Plug and Play Operating System = yes?  Is Power Management turned off at the BIOS level?  Does you BIOS have Boot Sector Virus detection, etc?

Actualy I was confused with the mobo Jumpers now that problem has been Solved. But after the bootup Screen Blue window pop ups "Error stop : 0x000000 7b " you need to recover your system. I had done it 4 times no luck so far. Is there anyway That I could reinstall my windoes Xp without losing any data?
I simply Changed the motherBoard and everything is running smooth Now. thanks everyone.
