Hi pawassius , i am happy to assist you , can you tel what is your really problem so that i can able to help you more , now i will just explain what is basic component in computer , to make it more clear i will tel in normal English.

Motherboard - its the main board for computer or laptop, all your device will be plug in to motherboard only just see the pic
I have the exact same - immortal4u_6.jpg
BGA - The BGA is descended from the pin grid array (PGA), which is a package with one face covered (or partly covered) with pins in a grid pattern. These pins conduct electrical signals from the integrated circuit to the printed circuit board (PCB) on which it is placed. In a BGA, the pins are replaced by balls of solder stuck to the bottom of the package.

immortal4u_7.jpg

GUI mean - A graphics processing unit or GPU (also occasionally called visual processing unit or VPU) is a specialized microprocessor that offloads and accelerates graphics rendering from the central (micro-)processor. It is used in embedded systems, mobile phones, personal computers, workstations, and game consoles.

The problem with the HP Pavilion dv2000, Pavilion dv6000, and Pavilion dv9000 series; is inadequate cooling for the graphics chipset.

The metal heatsink area on the Cooling Tube, is too small in surface area.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The I.C, or chipset used for graphics is the graphics chipset, or more properly known as the G.P.U.

The mounting to the motherboard is with a BGA surface mount.
Ball Grid Array.

The bottom of the graphics chipset has Solder Balls.
The mating area on the motherboard has matching Copper Pads, and they are gold plated.

The graphics chipset is set into place with the Solder Balls, lining up on the matching Copper Pads; and heat is applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset TO the motherboard.

Due to the constant overheating the solder connections (joints) made, are partially melted.
Then when the laptop is turned off the graphics chipset cools down, and the solder joints re-solidify.

This causes Cold Solder Joints, and a poor contact of graphics chipset to motherboard.

The solution is to add more surface area, to the small metal plate of the Cooling Tube, that sits on the graphics chipset.
Plus reflow the solder joints for the graphics chipset.

BEST, and surety of repair; of reflowing the graphics chipset's solder joints; is to use a BGA Rework Station.

Watch a BGA Rework Station at work, and also view more information about the BGA surface mount,

Dell l702x 17 motherboard


The chipset in reference is a graphics chipset.
Allow me to digress for a moment, and bring you up on a few basic things, so you know what we are talking about;

1) Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

2) The chipset, or Integrated Circuit for graphics; is a graphics chipset.
Proper term is G.P.U.
Graphics Processing Unit,

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

Upon reading the article, you will learn that the GPU can be mounted directly TO the motherboard, or mounted on a separate graphics adapter card.

You are probably familiar with the last term.
It's a graphics card. Also can be stated as video card.

Doesn't quite work that way in all laptops, or can be said, all laptop manufacturers.
Best way to sell a laptop? Make it seem better than it is.
Stiff competition.
Use the fuzzy definition of Graphics Card, and make the laptop seem better than it is.

Going back to the term GPU. The graphics processing unit, is actually the little chipset in the middle. Around it is a small circuit board.
The circuit board is an interface used to connect the GPU, to the motherboard, OR graphics adapter card. -> Such as used in a desktop computer.

Laptops usually have Integrated Graphics.
Means it borrows from the System Resources. The Processor, and Ram Memory.
Yes.
This means the Processor, and Ram Memory are overloaded, when an intensive program is run. Such as an intensive game, for example.

An actual graphics card has it's own Processor. The GPU. But, it also has it's own graphics memory. Means it does not borrow from the System Resources.
Makes the laptop perform better. Also makes it sell better.
See why laptop manufacturers want to 'fudge', the graphics that is REALLY installed?

It IS a graphics card, but it is mounted to the motherboard with a BGA surface mount. This makes it TOUGH to replace, therefore tough to upgrade. Not really a graphics card IMHO.



From what I can gather looking at the specifications, for the
Dell XPS 17 Model L702x, it can come with a separate graphics card, or the GPU is mounted to the motherboard. (Integrated Graphics )

If it is mounted to the motherboard, it is Integrated Graphics.
IF so, the GPU is an Intel HD graphics. The GPU is built into the Processor itself.

If it is a separate graphics card, it is an Nvidia GeForce GT 550M,
OR, an Nvidia GeForce GT 555M. (Two options were offered)
M stands for Mobile.
It is a graphics chipset built for a Mobile computer.
Which a laptop is.
It is Mobile because you can carry it around.

According to what you have stated, from what you have been told, the motherboard needs to be replaced.

This means to me we are dealing with Integrated Graphics, whereby the GPU is soldered directly to the motherboard.
(Not a separate, thereby replaceable, graphics card)

The mounting for the GPU, or graphics chipset, is a BGA surface mount.
Ball Grid Array.

To explain the BGA surface mount;
Compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.
I do not know if you are familiar with this. If so disregard the following;

The processor has contact pins on the bottom. 478 of 'em.
The processor socket has matching socket holes,

http://en.wikipedia.org/wiki/Socket_478

Now to go on;
With a BGA surface mount there are no contact pins, nor socket holes.

In place of the contact pins are Solder Balls.
In place of the socket holes are Copper Pads.
The Copper Pads are mounted directly to the motherboard, (Simple explanation), and gold plated.

The graphics chipset is set down on the motherboard, with the Solder Balls lining up on the Copper Pads.
Heat is applied at a specific temperature, and length of time.

This action melts the Solder Balls, and solders the graphics chipset TO the Copper Pads.
(Which in turn, of course, solders the graphics chipset TO the motherboard)

If the cooling system area for the graphics chipset is inadequate, the graphics chipset overheats.
Constant, repeated, overheating can cause the solder connections that were made, to partially melt.

When the laptop is turned off, the solder connections re-solidify.
This causes a Cold solder joint, or solder joints.
(The solder connection is a solder joint)

This cause a poor contact of the graphics chipset to the motherboard, and apparently what you are seeing.

I state apparently, because -> I do not have the laptop in front of me, and have not diagnosed the problem. Going by what you have stated, from what you have been told.

From the specifications I have seen so far, I see a touchscreen can be an option. Do I assume your laptop does Not have this option?

Now I would like to show you a BGA Rework Machine (Station), at work. Gives you more of an idea of what a chipset is, and the BGA surface mount,

This is an example of the CPU Heatsink, used to cool the Processor, and graphics chipset.
(Digressing; CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short),

http://www.parts-people.com/index.php?action=item&id=12048

Click on the image to enlarge.

You are looking at a Top view.

1) At the Top is a rectangular copper finned Heatsink.
It has thin pieces of a foam material that are black, on it.
(A type of Filter)

2) Coming away towards the right, you see two Cooling Tubes.
Slightly flattened copper tubes that are sealed on both ends, and filled with Nitrogen.

3) The first Large aluminum looking plate of metal at the Top, sits on the Processor. Two Philips head screws.
4) The rectangular shaped plate of metal at the bottom, sits on the graphics chipset.

The Fan Assembly is not shown. This is an example of it,

http://www.ebay.com/itm/Genuine-NEW-Dell-XPS-L701-L701X-L702X-CPU-COOLING-FAN-DFS601305FQ0T-W3M3P-/260861096735

(Scroll down)
Left side is the Bottom, that sits on the motherboard. Right side is the Top.
The Fan sits next to the rectangular copper finned Heatsink.

Heat from the Processor, and heat from the graphics chipset, si absorbed by their respective metal plates. The heat is then absorbed by the Cooling Tubes. The Cooling Tubes transfer the heat to the finned Heatsink.

The Heatsink absorbs the heat, then radiates it away with the thin fins. Air flow from the Fan Assembly helps carry heat away from the fins of the Heatsink.

That rectangular metal plate sitting on top of the graphics chipset, is TOO small in surface area. The surface area needs to be increased.
How? Here is one tech's idea. It has been around a long time, just showing you an example. This is towards certain HP laptops.

How do i change my graphics card


Yes, and no.

Pretty clear huh? lol!

Let me explain a few rudimentary things first. May be a long read, and a 'bumpy ride'.

ONE:
Laptop manufacturers tend to 'exaggerate', in order to sell laptops.
They can get away with this due to their 'advertising license'.

"This laptop has an XXXXXX graphics card"

When in reality it isn't a graphics card. It is a graphics chipset soldered directly to the motherboard.

The term 'graphics card' is used rather loosely.

A graphics card is actually a graphics adapter card.

The graphics chipset is soldered to a circuit board, or 'card'.

The circuit board has contact pins on it, which plug into a connector on the motherboard.

This is a basic example for a desktop computer,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7168071

A graphics card made by Powercolor, and uses the AMD ATI Radeon HD5450 graphics chipset.

Left-click on the photo of the graphics card shown at the top.
It will come up in a separate window.
In the views at the Bottom, click on the second view from the left.

Here you will see the gold plated contact pins.
To show the gold plated contact pins in more depth, let's look at an average SO-DIMM ram memory module, for a laptop,

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

[ You can click on the photo to enlarge. You can enlarge twice ]

These gold plated contact pins go down into a slot. A graphics card slot. (Expansion slot on the motherboard)

For laptops that TRULY do use a graphics adapter card, they use the MXM technology. There IS a graphics adapter card, and it DOES plug into the motherboard.

This is an example of an ATI Radeon HD5450 MOBILE graphics card, that uses the MXM technology,
(Mobile meaning for a laptop. Laptops are a Mobile computer. Can take it with you wherever you go),

http://www.ebay.com/itm/HP-ATI-Mobility-Radeon-HD-5450-MXM-Type-A-Graphics-Card-512MB-DDR3-608544-001-/190626056695?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item2c6232c9f7

Here you see the gold plated contact pins again. Means this mobile graphics card, (Mobile meaning laptop), plugs into the laptop's motherboard.

It is mounted to the laptop's motherboard, with screws through those brass ringed holes you see. (Probably with just two holes)

MOST laptops do not use a graphics adapter card, based on the MXM technology.
They just have a graphics chipset soldered directly to the motherboard.

Let's regress for a moment, and let me explain Chipset, GPU, and BGA surface mount.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

[ A Processor is just ONE example of an Integrated Circuit ]

G.P.U. stands for Graphics Processing Unit,

The chipset, or Integrated Circuit, for graphics, is a GPU,

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

Left-click on the photo to the upper right, that the heading states,
GeForce 6600GT (NV43) GPU

The actual GPU (Goldish/brown square), is in the center of that square
green circuit board. The GPU uses the green circuit board, to connect to the motherboard.

The entire thing you see is termed as the graphics chipset, or GPU.
This is because that circuit board is actually part of it.

BGA surface mount:
Ball Grid Array,

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

To explain a BGA surface mount;

Compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

This particular processor socket has 478 socket holes.
The bottom of the Intel Pentium 4 processor, has 478 contact pins sticking out of the bottom.

With a BGA surface mount there are No contact pins on the chipset, (GPU in this case), nor are there socket holes.

The bottom of the graphics chipset has Solder Balls.
The motherboard area where it mounts, has matching Copper Pads.
(The copper pads have a gold plating on them)

The graphics chipset is set into place, over the matching copper pads on the motherboard, and then heat is applied.

Heat is applied at a specific temperature, and length of time.
This action melts the solder balls, which in turn solders the graphics chipset TO the copper pads.

[ Which in turn of course, solders the graphics chipset TO the motherboard ]

IF, you have a graphics chipset, THAT uses the MXM technology, and IS an actual graphics adapter card, you MAY be able to upgrade it.

IF, the graphics chipset is Integrated Graphics, and therefore uses the BGA surface mount, I would forget about it.

Replacing means using a BGA Rework Machine.

However things get more complicated, than just replacing a graphics chipset, that uses the MXM technology.

It isn't, " OH, it's a graphics card? I'll just take it out, and use a better graphics card."

Depends on what the motherboard chipset is, and what type of graphics interface it uses. PCI, or AGP, or PCI-Express.

(PCI, and AGP, and PCI-Express, are technologies. Doesn't just refer to the type of expansion slot )

Let's look at the specifications, for the Gateway NV59C41u Notebook PC,...(Continued in an additional Comment)

When the Caps Lock flashes, it is then being used in a diagnostic mode. 5 times flashing means a problem with the System Board.

Motherboard.

I don't doubt it.

Two common problems, all based on one issue.
Overheating.

1) Problem One;

Primer;
The Processor, and the GPU are the two hardware components that produce the most heat.

[ GPU = Graphics Processing Unit. Slang? Graphics chipset,

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

GPU,

http://en.wikipedia.org/wiki/GPU ]

It could be something as simple as foam has melted, and melted down onto the motherboard, near the Processor socket. Removal puts the laptop back into service again.

It could be much more complicated, and follow an issue that has beleaguered the HP Pavilion dv2000 series, dv6000 series, and dv9000 series.

The cooling system for the GPU is inefficient. Allows the GPU to overheat.
Constant overheating partially melts the solder connections of the GPU to the motherboard.

The graphics chipset (GPU) is mounted to the motherboard with a BGA surface mount.
Ball Grid Array,

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

To explain the BGA surface mount;
Compare to an older Intel Pentium 4 processor, and it's Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

The processor has contact pins on the bottom. (478 of 'em) These line up with matching socket holes in the Socket 478 processor socket. (478)

With a BGA surface mount there are no contact pins, nor socket holes.
Solder Balls take the place of the contact pins, and Copper Pads take the place of the socket holes.

The graphics chipset's Solder Balls, are lined up with the matching Copper Pads on the motherboard.
Heat is then applied at a specific temperature, and length of time.

This procedure melts the Solder Balls, and solders the graphics chipset to the Copper Pads.
(Motherboard)

With constant overheating the solder connections that were created, start to melt. This creates a poor connection.

The professional method to repair this problem, is to use a BGA Rework Machine, to Properly re-solder the connections.

Due to the location of repair shops that have a BGA Rework Machine, and the C-O-S-T, many are attempting to perform the procedure with a non-professional method.

A thin metal shield is cutout in the middle, for the graphics chipset. This shield is set over the graphics chipset, and lays on the motherboard. Heat is then kept just to the graphics chipset, and the other components on the motherboard are protected.

Heat is applied with a propane torch, or a hot air gun, (Not hair dryer), in a circular (Spiral), pattern to the graphics chipset. With a more proper method used, the tip of a thermometer that can read this heat range, is laid on the chipset, and is used to keep the chipset at a specific temperature.

(Too much heat will burn up the chipset. Too little will not properly remelt the solder connections. A Cold Solder joint, or joints, will result)

The heat from the heating instrument, (Propane Torch/Hot Air Gun), is rotated around in a spiral pattern on the chipset. Constant moving around to distribute the heat evenly.
(You do not want a 'hot spot')

When the specific heat range is met, the heating instrument is slowly moved away from the chipset.

Move up an inch or so, keep spiraling. Then move up another inch or so, and keep spiraling the heat source. Slowly move up in increments while spiraling. S-L-O-W-L-Y back away. Method is used so that the chipset slowly cools down. Otherwise a cold solder joint, or joints, could result.
(Right back to where you started)

This link is to a video that shows one style of the procedure. It is not an advertisement for the video, just linked for the procedure information,

Your diagnosis is correct abhisheks27, it is a graphics 'engine' issue.

The HP Pavilion dv6835nr is one of the HP Pavilion dv6000 series of Notebook PC's.

The Pavilion dv6000 series Notebook PC's have an issue with inadequate cooling for the GPU.

{Graphics Processing Unit, or graphics chipset,

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

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

The cooling system consists of the Fan Assembly, Heatsink, and Cooling Tube.

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv6500-dv6600-dv6700-dv6800-notebooks/

Scroll down the page to Step 18, and it's second photo.
Here you are looking down at the top of the laptop, and can see the Fan Assembly, in the top left corner.

Steps 25 and 26 show the bottom of the motherboard, the Fan Assembly, Heatsink, and Cooling Tube.

The Cooling Tube is a hollow copper tube, slightly flat, and is filled with Nitrogen.
You can see it's curved J shape.

Looking at the photo in Step 25 observe the aluminum looking X shape, at the left side of the Cooling Tube. It has 4 red circles marking it's mounting screws.

This X-shaped object is a flat plate. It is a type of Heatsink.
This particular metal plate sits on top of the Processor.

Heat from the Processor is absorbed by this plate, then transferred to the Cooling Tube.

Observe the next aluminum looking plate to the right. Looks like a square tab, attached to the side of the Cooling Tube.
This metal plate sits on top of the GPU.

Heat is from the GPU is absorbed by this plate, and transferred to the Cooling Tube.

{Step 26 shows the top of the Processor uncovered, {Processor (CPU) }, and the GPU uncovered.
The GPU is the greenish square to the right of the Processor }

The cooling area (Size) of the small plate of metal, that sits on top of the GPU, is inadequate.
It cannot absorb enough heat away from the GPU.

This leads to the GPU overheating.

The GPU is mounted to the laptop's motherboard with a BGA surface mount.
Ball Grid Array.

To explain the BGA surface mount technology, I'm going to use an older Socket 478 Intel processor.

The Socket 478 Intel processor's have pins on the bottom of them. These pins line up with socket holes in the processor socket.

With the BGA surface mount there are no pins on the bottom of the chipset. (Chipset circuit board, actually)
There are Solder Balls in place of the pins.

On the motherboard there is no socket. In it's place there are Copper Pads.

The chipset is set into place on the motherboard, with the solder balls lining up with the copper pads.
A specified temperature of heat is applied, and this melts the solder balls. The chipset is soldered to the copper pads on the motherboard.

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

When the chipset overheats, (In this case the chipset is the GPU), the solder balls start to partially melt again.
This causes a poor connection due to cold solder joints.

{The solder balls have melted, and rehardened again. Not done properly this causes a cold solder joint }

The poor contact of the GPU to the motherboard caused by inadequate cooling, is the problem.

The solution is too have the GPU's BGA surface mount reflowed, and to install a better Heatsink plate for it, or add to the heatsink plate.

This is to show you more in-depth as to the problem. It also shows a possible solution.

I am Not providing this link for the possible solution it provides. The tech is also advertising selling a repair. I do not advertise for other people, and know nothing of this tech.
