Mother Board part?

no and no. the CPU or Processor is not included in a motherboard. if your buying a completely different board from the one you have you may need to expend a few hundred more to buy a new processor to match. also you may have to buy new RAM depending on the new board vs the old board. also you need to match up the PIN number of the board to processor. if its a 966 pin you need a 966 pin processor to match. and RAM DDR1,2,3 to same.

you do not need to buy a new hard drive as long as you dont need a new one. but when you replace a motherboard windows will demand you re enter your activation key before it will open right back up to you. so make sure you have it handy.

It seem that changing the mother board was needed to confirm as there seems to be a problem related to non communication of the mother board with the CPU, RAM and sections.
Swap and confirm.

The graphics chip.

The HP Pavilion dv9310us is one of the Pavilion dv9000 series of Notebook PC's.

The dv2000, dv6000, and dv9000 series of HP Pavilion Notebook PC's, all have an inherent problem they share.
They have a poor cooling design for the Processor and the graphics chip.

A Chip or Chipset is an Integrated Circuit. Chip and Chipset are slang terms.

http://en.wikipedia.org/wiki/Integrated_Circuit

A graphics chip is attached to a small circuit board. (PCB) The board itself is attached to the motherboard via a surface mount type of technology.

BGA. Ball Grid Array.

To explain this type of mounting I will use an older Processor for an example.
The older Processors used pins on the bottom of them. These pins lined up with matching socket holes in the processor socket.

[Newer Processors have the socket holes, while the processor socket has the pins]

On the BGA type of surface mount, there are no pins protruding from the bottom of the graphics chip's circuit board.
There are solder balls.

On the motherboard there are matching copper pads.
The graphics chip is set in place on the motherboard so that the solder balls line up with the copper pads, then heat is applied, and the solder balls melt.

This action solders the graphics chip directly to the motherboard.
(Integrated Graphics. Also known as OnBoard Graphics. ON the motherBOARD)

With the poor cooling design of the above mentioned Pavilion DV series, the graphics chip overheats, and the solder connections begin to unsolder.
This makes a poor connection between the graphics chip, and the motherboard.

Dear vijay, Please check your power ic of mother board there is problem. When you change it then your cpu and processor fan will be working.
Thanks. Rakesh.

Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty because a computer has to have an end to the circuit any fulty leads will lead to no boot up
good luck

YEs you can purchase new processor fan and also if you are some tech savvy then you can change its clip.
BUt new processor fan purchase is good choice becasue not cost of it.

have u check ur memory?... ur videocard and powersupply...thats the main problem of pc if it has no display....just try it one by one...hope it can help u

All major motherboard manufacturers offer this support on most boards. The em64T indicates the processor is capable of running 64-bit operating systems and software. Do you already have a processor and if so what model is the processor? Based on the processor model you'll need to select a motherboard that has the correct socket type and bus speeds.

That board used a ZIF (Zero Insertion Force) Socket that has a small lever attached to it that will rotate the CPU out of its locked-in position.

Disconnect the main power cable from the back of the computer - the one that is plugged into the wall. Make certain that the power is off to the display.

After being certain to ground yourself and remove any static electricity, detach the power connector for the fan and then carefully open the ZIF Lever.

With the lever in a fully upright position carefully grip the fan chasis and ease the chip straight up. Be aware that the chip has a number of delicate pins on its base which is how it plugs into the motherboard and if any of these are bent or moved out of alignment it can both damage the chip and make it difficult to re-install it.

If you are upgrading the CPU be aware of the following:

You will need to reconfigure the motherboard settings for the new CPU

You will want to use thermal paste when attaching the new heatsink and fan.
