Is the heat sink the same on a motherboard that does not have a video chip and one that does?

You do need much. Just cover the heat sink with a thin layer of thermal paste, the excess paste will squeeze out when you clip the heat sink over the CPU so do not put too much paste on.

INSIDE A COMPUTER OR THE HEAT SINK FOR YOUR COMPAQ COMPUTER?

The "CPU" or central processing unit, otherwise known simply as "the processor," is the primary "brain" of the computer. Processors are very finely engineered components that are not repairable. But replacing a failed processor is an option for the owner of any model Compaq Presario desktop computer. Just check with HP/Compaq for the correct and speed of processor for your motherboard before purchasing a replacement.

Turn off the computer and disconnect all cables. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the cover. Lay the computer down flat. If there is a plastic hood covering an exhaust fan, remove it by pressing in on the indicated release tabs. Examine the processor assembly. The processor is a square chip that is covered by a metal heat sink with fins. A fan will often be mounted on top of the heat sink; unplug its connection to the motherboard. Two clips usually secure the heat sink assembly to the top of the processor. Gently press down and slightly away on the flat end of a clip to release it. Avoid using a screwdriver to release a clip; a slip could scratch the motherboard. Release the clips and gently remove the assembly. The heat sink should separate, leaving the processor behind in the chip holder. Clean the bottom of the heat sink. Use a paper towel and a dab of solvent cleaner to remove the old thermal paste. Set the clean heat sink aside. Lift up the lever to unlock the old processor and remove it from the pin mount. Insert the new processor chip. Align the pins on the processor to the "cut off corner" or dot on the pin mount. The processor should drop into the pin holes easily. If the processor won't drop in easily, check the pin alignment. Once the processor is inserted correctly, pull down the lever to lock in the chip. Apply thermal paste to the bottom of the heat sink. Apply enough paste to cover the area of the small gray rectangle on top of the processor. Apply the paste with a spreader made from a piece of flexible plastic. Spread the paste evenly to a thickness of two sheets of paper. Check the heat sink mounting alignment and lower the heat sink onto the top of the processor. Reinstall the mounting clips. Reattach the heat sink fan to the motherboard if necessary. Plug in the computer and monitor and boot. If the machine won't boot or it emits warning "beeps," unplug the power and monitor, and troubleshoot your work until the computer boots successfully. Shut down again and replace the exhaust fan hood. Close up the computer and reboot. Hope this helps.

The "CPU" or central processing unit, otherwise known simply as "the processor," is the primary "brain" of the computer.

Processors are very finely engineered components that are not repairable.

But replacing a failed processor is an option for the owner of any model Compaq Presario desktop computer.

Just check with HP/Compaq for the correct size and speed of processor for your motherboard before purchasing a replacement.

Turn off the computer and disconnect all cables.

Remove the cover.

Lay the computer down flat.

If there is a plastic hood covering an exhaust fan, remove it by pressing in on the indicated release tabs.

Examine the processor assembly.

The processor is a square chip that is covered by a metal heat sink with fins.

A fan will often be mounted on top of the heat sink; unplug its connection to the motherboard.

Two clips usually secure the heat sink assembly to the top of the processor.

Gently press down and slightly away on the flat end of a clip to release it.

Avoid using a screwdriver to release a clip a slip could scratch the motherboard.

The hp dv6000 has a video card issue that is very comman the cpu heatsink and the video card and conncted to the same copper heatsink and what happens is the video card overheats and the pins that are soldered to the board come loose now there is a couple of ways to fix it option a is to take the laptop apart and remove the motherboard and heatsink and the cpu chip then locate the video chip and isolate the video card and heat it up to remelt the solder points this can be done by taking a aluminum can and cuting out the square that is same size of video chipthen with a heat gun heat up the chip so the solder joints remelt to the board but BE VERY CARFUL IF YOU OVER HEAT THE CHIP IT WILL MELT once the chip has cooled then reistall your cpu chip add new thermal paste and get a flat square piece of copper the size of the cpu chip and put it on the cpu chip then add more thermal paste and put the heat sink back on and reassemble the laptop and if you didnt damage the chip it should fire right up option b is to buy a replacement motherboard that has the upgraged heatsink installed and put that in but make sure yoyu order the right board check the replacement part number sticker on the motherboard and make sure yoyu order the right one i have done this process to about 200 of these hp dv6000 and they are still working today

First step would be to check all cooling fans are running correctly. Second blow out the dust and debris from inside the computer. If the cooling fans are not running correctly you will need to replace them. Thrid have you added any new hardware or have cables that would interfere with airflow? If so move things around so you have good air flow around the processor. Finally (before we get into the professional portion) you might try adding additional fans to the case, there are fans that will go in a drive bay to help improve air flow.

CAUTION!!!! The following steps should only be taken by a competent professional:

1. Check the heat sink, is there thermal paste leaking out around it (too much paste was used). You will need to remove the heat sink, clean up all thermal paste and then remount the heat sink with a small amount of thermal paste.

2. Remove the heat sink, is the thermal paste dried up? If so, inferior thermal paste was used. Clean up all the old thermal paste with alcohol, replace the heat sink with a small amount of good thermal paste.

Of course if you are running the computer in an 80 degree room, that will affect temperature too.

Hope this helps.

The video chip may have over heated just like several of the Compaq models.If this is the case then you need to take the laptop apart and heat the video chip to about 200 degrees and it will fix the issue. Also you need to add some copper strips to the heat sink along with thermal paste witch it does not come with from the factory with thermal paste. That will take care of the overheating and always make sure you keep your heat sink clean as that will cause it to overheat as well. There is several videos on Youtube that show you how to do this same thing. Hope it helps!!!

1 Go Online and get a good repair guide
2 Open the case and get access to the motherboard. This is actually the trickiest part of the process and needs a bit of patience. Just be careful not to lose any screws or damage the case.
Step 3: Remove the X-Clamps. These are the clamps that keep the heat sinks attached to the main CPU and GPU (graphics processor) chips. It needs to be removed from under the mainboard and care needs to be taken not to bend the clamp as you will be putting it back on.
Step 4: Use heat paste and fit risers. You need to use some CPU thermal paste to make the heatsinks more efficient - this will prevent the console from overheating again. Reattach the heat sinks using some polythene risers to give a better seal

those xs on the motherboard are supposed to be there. they alow the procesers to get good conection to the heat sinks. put the xs back on and then go out and buy some thermal paste. (can be found at best buy or radio shack or anystore that carys alot of electronics) just spread a very THIN layer over both of the proccessers under the heat sinks and put the xs back on. unless you got the kit that screw the heat sinks to the the motherboard. but if u just took off the xs and left it put them back on and out thermal paste on the processers.

That is the 'Northbridge' chip that provides the I/O interfacing for the main chip. The heat sink is normally held on with glue as you surmised, and should be re-done with a thermal conductive glue. The glue (a silver filled epoxy) is available from MCM electronics or from Mouser. Be sure to thoroughly clean the chip and heat sink before re-gluing.
