fbhushan, the Intel D101GGC motherboard (Grand Country) supports;
1) Intel Pentium 4, Intel Celeron D, and Intel Pentium D processors that fit in an
> LGA 775 processor socket.http://en.wikipedia.org/wiki/LGA_775
The Processor has the socket holes, and the processor socket (LGA 775) has the pins.
775 socket holes, and 775 pins.
The Front Side Bus (FSB) can be either 533MegaHertz, or 800MHz.
2) Supports DDR Sdram ram memory at either 333MegaHertz or 400MHz.
(PC2700 and PC3200, respectively)
Will support Up To 2GB of ram memory.
Has two ram memory slots. The maximum amount for EACH slot is 1GB
3) The SMPS used for it has,
A) One 24-pin ATX main power cablehttp://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24
B) One 4-pin ATX +12 Volt power cable,http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4
The Intel D101GGC motherboard has Four SATA headers (Connectors) on it, so I'm going to assume you are using a SATA harddrive.
This would mean the SMPS you are using should have at least one SATA power cable.
It should also have an assortment of 4-pin standard Peripheral power cables.
(Misnomered as 'Molex')
The Asus P4SD (Motherboard chipset Intel 865PE) supports;
1) Intel Pentium 4 and Intel Celeron processors that fit in a > Socket 478 processor sockethttp://en.wikipedia.org/wiki/Socket_478
The Processor has the pins, and the processor socket has the socket holes.
478 pins, and 478 socket holes.
Your Processor will NOT work.
The Ram Memory WILL work.
The SMPS MAY work.
I state MAY because the Asus P4SD motherboard uses a 20-pin ATX main power cable.
If the last four pins of the 24-pin ATX main power cable that you have on your SMPS right now, Do Not remove, you can Carefully cut them off. Wrap them up, and out of the way.
If you need guidance on this I can help instruct you.
You need an IDE (PATA) harddrive, or a SATA adapter card to use a SATA harddrive.
So there you have it sir.
