Online chat good day to you, i have acer 5920g but video card burnt( nvidia geforce 8600m gs) i would like to change it but are there any other videos supported by my motherboard? for example 9300m gs or others.

Well the first thing I would try is to hook the computer up to an external monitor to check and see if the video controller itself is causing the problem.... If the same thing happens on the external monitor, then it's the controller hardware or the driver.... so to rule out the driver, download a different version of the driver for that card and install it. If the same thing still happens, then you should suspect the card itself, and yes, on a laptop the video card is integrated on the motherboard, so if it needs replacing, then you must swap the whole board. Hope this helps!

SOURCE: no solution found. I wonder if the solution exists

Follow the instructions at the bottom of this page for the sound card:

for the video card: http://www.opendrivers.com/freedownload/284952/nvidia-geforce-8700m-gt-8600m-gt-8400m-gs-8400m-g-forceware-driver-176.37-windows-xp-x32-download.html

Hi,

It seems that you have an integrated video card.

let me give you two options.
upgrade your mobo and video card which will probably cost you $500.00

or upgrade your memory for $200 to increase shared video memory.

hope this helps.

thanks,.

SOURCE: I have a HP DV9830us with a NVIDIA GeForce 8600M GS GPU that is giving me a blank screen that is on.

AM GLAD you posted first!

Yes; the HP pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series; all have inherent problems with indequate cooling; for the graphics chipset.

Let me explain, and you'll see what is going on. Apologizes in advance for the long read. (I guess -> I, am the manual, lol!)

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

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

The I.C., or chipset for graphics; is a graphics chipset, or more properly known as the G.P.U.
Graphics Processing Unit,

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

The GPU you are referring to is an Nvidia GeForce 8600M GS.
A Mobile graphics chipset, (Laptop is a Mobile device. Desktop computer is not),

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_8_.288xxx.29_series

Scroll down. GeForce 8600 GS in left column.

This is what it looks like,

http://www.ebay.com/itm/1-NEW-nVIDIA-Geforce-8600M-GS-G86-741-A2-G84M-Chip-BGA-/330632950894?pt=LH_DefaultDomain_0&hash=item4cfb42746e

Looking at the large main view, you are looking at the Top View.
The black rectangular chipset in the middle, is what the Cooling Tube's small metal plate, sits on. More on that later.

In the small views shown (2), click on the one to the Right.
The Left side again shows you Top Views, the Right side side shows Bottom views.

The Bottom has Solder Balls. The Bottom is mounted TO the motherboard.

If we compare an older Intel Pentium 4 processor, that uses a Socket 478 processor socket; we see the bottom of the Processor has Contact Pins; and the processor socket has matching socket holes.
(478 pins, 478 socket holes),

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

The graphics chipset for your HP, is mounted to the motherboard with a BGA surface mount.
Ball Grid Array.

In place of the contact pins are Solder Balls, on the bottom of the graphics chipset.
In place of the socket holes are Copper Pads, on the motherboard.
{They are also gold plated. Just like Ram Memory module ('Stick') contact pins}

Read closely;
The graphics chipset is set down onto the motherboard, with it's Solder Balls lining up on the matching Copper Pads, of the motherboard.

Heat is then applied EVENLY, at a SPECIFIC temperature, AND length of time.

This action melts the Solder Balls, and solders the graphics chipset TO the Copper Pads.
Can also be stated as solders the graphics chipset, TO the motherboard.

Due to inadequate cooling FOR the graphics chipset, the solder joints made, (Solder connections), begin to partially melt from constant overheating.

When the laptop is turned off, the solder joints then re-solidify.
This causes Cold Solder Joints, and a poor contact of graphics chipset TO motherboard.

Hence what you are seeing.

To remelt the solder joints, is to reflow them. Referred to as reflowing the graphics chipset, in this case. (Or can be said as reflowing the BGA surface mount)

THIS WILL NOT DO!
The problem will come up again!
-> Inadequate cooling for the graphics chipset.

The surface area for the graphics chipset, needs to be Increased.

Now to explain the cooling system;
The cooling system consists of a Cooling Tube, Heatsink, and Fan Assembly,

http://www.geeks.com/details.asp?invtid=434678-001

You are looking at a Bottom view. Turn it over, and it mounts on the Processor, and graphics chipset.

In the front you see the aluminum D-shaped fan housing. The fan is Black, and in the middle.

What cannot readily be seen, is the fins of the Heatsink. The Heatsink is that Black rectangular object, in the very front of the D-shaped aluminum fan housing.
The Heatsink is a small thin piece of metal, that has Tall, Thin fins, protruding from it.

At the back is the Cooling Tube. Slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.
Note also the two small rectangular copper plates.

The small plate at the back, with the Y spaced mounting arms, is for the Processor. The one closest to the D-shaped aluminum fan housing, is for the graphics chipset. (Has small square blue Thermal Pad, on it)

That little rectangular copper 'bump', (Plate), is TOO small in surface area. Let's the graphics chipset overheat. POOR design.

Heat is absorbed from the Processor, and graphics chipset; by the two respective small copper plates of the Cooling Tube, that sits on them.
Heat is then absorbed by the Cooling Tube.
The Cooling Tube transfers the heat up to the Heatsink.

The fins of the Heatsink radiate the heat away.
Air flow from the Fan Assembly, helps carry the heat away from the fins, of the Heatsink.

This is what one tech has come up with. Posting for REFERENCE, and specifically; increasing the surface area of the cooling tube plate, for the graphics chipset. Not advertising for this guy,

http://www.youtube.com/watch?v=bnkQNmKauEc

I do NOT subscribe to using a Heatgun.
Why?
The heat MUST be applied EVENLY. The entire surface of the graphics chipset. Cannot be any 'cold spots'.
Outside perimeter, and inside area; must be heated the same.

The heat MUST be raised to a SPECIFIC temperature, and KEPT there for a Specific length of time.
To gauge it a special type of thermometer is used. A Heat Probe.

The chipset then NEEDS to be cooled down slowly. Otherwise 'Cold Solder Joints' will occur.

I don't even like his torch method.

{However; he has videos for the dv2000 series, dv6000 series, and dv9000 series. I have read in Comments from him, that he agrees the BGA Rework Station is the BEST method )

The PROPER method is to use a BGA Rework Station. Not something an average computer repair shop has. HP, Acer, Toshiba, Lenovo,....you name it; sends the motherboard out to a specific shop; that has a BGA Rework Station.
(Or just scraps the motherboard)

View a BGA Rework Station in action, and learn more about the BGA surface mount,

http://www.ersa.com/art-ir-pl-650-346-1472.html

Scroll down, click on the Red -
Take a few minutes to view the IR 650 demo video

Also; using an oven is d-umb. Heats ALL the chipsets, and can permanently ruin a motherboard.

Make SURE you wear an ESD wrist strap, and connect it's alligator clip to a good ground source. Your body carries Static electricity, and Static WILL fry out (Short Circuit), the delicate hardware components in a computer.

[Electro Static Discharge. Average cost is $3 to $6.
Here is but one example,

http://www.radioshack.com/product/index.jsp?productId=2103245

It isn't a piece of wire attached to your wrist. There is a metal plate in the wrist strap; that touches your wrist. That is connected to a Capacitor, then to the wire for the alligator clip.

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
I feel an Anti-Static Mat is unwarranted.
{Also do not want my wrist connected to the local, yokel, electric companies ground source. If you catch my drift}

You can also set a large metal serving plate (Unpainted), on the TABLE you're working on, and connect to it.
Or a large metal knickknack. (Unpainted ]
