|"This same CPU was |
working on the same motherBoard fine previously."
OK, then the mboard's bios is probably already able to recognize the cpu type properly.
"Actually since I noticed this problem I formatted the system
4-5 times but no effect Found."
It should have been obvious once you had formatted it once that you hadn't figured out what your problem was.
"About the C Partition,Total capacity of This partition is 78 GB and Only 13 GB occupied."
OK, then your C partition is not too full - that's good, and is not a possible cause of your problem.
"This MB is manufactred by Simmtronics and based on Intel Chipset i945G.."
"If it's not an Intel made mboard, the model is usually printed in obvious larger characters on the surface of the mboard, often between the slots. "
Did you look for that?
If you don't see that, look for stuck on labels that might have the mboard model printed on them. The one for the mboard itself often also has a bar code printed on it. Sometimes the label with the model printed on it is on the top of the parallel port, when your mboard has one.

These are the only i945G mboards they list - i945GC chipset models.
I suspect your mboard is the first one, unless yours is older and they have no support for it.
I see in all three cases, they do not list drivers for the 945 series main chipset. Sometimes mboard makers omit listing those drivers because there may be newer main chipset drivers on the maker of the main chipset's web site, and they don't want to have to update their main chipset drivers download.
You MUST install the main chipset drivers in order for the operating system to have all the proper info about your mboard, and for it to be able to properly support your cpu, and for it to be able to run your drives at their rated max speed.
E.g. Your mboard has USB 2.0 controllers. All USB 2.0 controllers also have USB 1.1 support - support for USB 1.x is always installed when you install a Windows operating system, Win 98 and above, but the support for USB 2.0 controllers is NOT installed in the operating system until AFTER the main chipset drivers have been installed.
After Windows Setup has finished, you MUST install the drivers for the components on your mboard, especially the main chipset drivers.
The CD that came with your mboard probably has all the necessary drivers, including the main chipset drivers.
However, if you have been going to the Simmtronics web site and loading only the drivers listed for your mboard there, they DO NOT list the main chipset drivers.
In that case, or in any case if you want to load the latest available main chipset drivers, go here:
You MUST download and install this
INF Update Utility - Primarily for Intel® 5, 4, 3, 900 Series Chipsets
Optional - the latest onboard video drivers
Intel® Graphics Media Accelerator Driver for Windows* XP (exe)
If you have already installed video drivers, un-install any listings in Control Panel - Add/Remove Programs for the onboard video BEFORE installing the video drivers software installation.
If that doesn't help, go into your mboard's bios Setup and load bios Defaults, or, better still, Optimized defaults if that's listed, Save settings.
The Simmtronics web site has no mboard manuals you can download; therefore, I don't know which key you must press to get into the bios Setup.
Often that's displayed on your screen while booting.
If you don't see that, try pressing Del, or F1, or F2, repeatedly while booting, starting early in the boot - e.g. right after the mboard beeps once,
or - if your mboard came with a printed manual, and/or a mboard manual that's a *.pdf or Word (*.doc) document that's on the CD that came with it, look at that to find out which key you press to get into the bios Setup - that's usually stated at the beginning of the descriptions of the bios Setup settings
