|"Can you tell me if light is coming on the board, Fan is running so it sounds like mother board is working fine, isn't it? "|
Those things can be working, yet your system won't boot all the way because of problems with hardware - most likely the ram connection is iffy or the power supply is faulty.
" My main worry is that board were not be lost"
Usually there's nothing wrong with the mboard or the cpu - processor - usually something else is wrong .
"If I boot the system, keep it at idle for some time, the Fan restart in a frequent interval"
Did you have the case opened up and you actually saw that, or you didn't and are assuming a fan is restarting by what you heard?
The cpu fan should never stop spinning, but it might spin faster when the cpu has warmed up some, then slow down when it gets cool enough. Some power supplies have fan s that respond to temperature the same way. Some case fans have a temperature control and may respond to temperature the same way, but that's rather uncommon.
Are you sure it's a fan you're hearing? If you have a disk in a CD or DVD drive, Windows spinsthe disk at random times and when it does, the led on the front of thedrive doesn't necessarily light up. Remove any disk you have in a CD or DVD drive to eliminate that possibility.
"I removed both HDDs and CD Rom connecting to Mother board, still I could not see the very first bios blue screen."
That has no effect on whether the mboard works properly, unless one of the drive's board is seriously defective, which is quite rare. The mboard itself should work fine, and you should be able to get into the bios and navigate it's pages, even when no hard drive is connected, if nothing else is wrong.
NOTE that you usually can't use a mouse in the bios - you usually can only use keyboard keys.
"I removed jumper from board, and restart the machine.. it was beeping and once I down the machine and reconnect with the jumper, similar behavior appears."
If you mean the clear cmos jumper, you're supposed to move it to the clear position, when the AC power to the case/ PS has been removed, wait a short time, then move it back to the normal position, then restore the AC power to the case/PS. You're not supposed to run the computer when the jumper is in the clear cmos position. In most cases you do not remove the clear cmos jumper, you move it to other pins - the mboard cannot work normally if the cmos jumper is on the pins for clear cmos, or if the jumper is removed when it isn't supposed to be removed.
"Do you have any thought of, that, if I could have windows 98 bootable CD or bootable Floppy, it will make difference?"
Your problem propably has nothing to do with the data on the hard drives - it's probably caused by a hardware problem of one sort or another.
The specs you supplied state this computer has XP on it.
- a Win 98 or 98SE CD cannot recognize the partitions on the hard drive, and can't see any files or folders on the partitions, unless they are using FAT32 or FAT partitioning. XP only allows you to use FAT32 partitioning if the partition is smaller than 32gb, and even then NTFS partitioning is selected by default.
So - a Win 98 or 98SE CD is useless regarding seeing whether the data on the hard drive is okay, if the partitions are all using NTFS partitioning.
- If your computer has a floppy drive, certain programs on a floppy disk can be useful - e.g. you can test the ram or the hard drives - but there are few that can examine the contents of the data on the hard drives.
- Certain bootable CDs or DVDs other than a Windows XP CD in a CD or DVD drive can be useful if you need to fix some problem with the data on the hard drive, or you can test the ram or the hard drives.
"I tried with Del and <F2> both. Your are right, BIOS become faulty"
Your symptoms do not necessarily indicate your bios is faulty - almost always, there's nothing wrong with it, unless you attempted to flash the bios and haven't said so and that was not successful. Your symptoms are probably caused by a hardware problem of one sort or another.
