One of two problems, or maybe a combination of both.

1) The laptop is dirty inside. Using a can of compressed air from the outside, (ALL power removed FIRST!), will NOT do the job.

Using compressed air in the air intake duct, (NEVER in the exhaust duct!), will just shove the 'Gunk' in further.
('Gunk' = Dirt, dust, hair, lint, food crumbs, etc)

The laptop needs to be disassembled, and a THOROUGH cleaning done.
(Not just take the top off, and bl-ow air around, and perhaps use Q-tips, and a soft small brush.

The cooling system assembly needs to be removed, and everything Thoroughly cleaned, to include the rest of the inside of the laptop.
Plus, it is GOOD advice to clean, and then replace the Thermal Paste )

2) It is because of a graphics chipset cooling problem. The cooling for the graphics chipset is inadequate. Plus barely enough for the Processor.

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

The graphics chipset is a GPU,

The cooling system for the Pavilion dv2000 series of Notebook PC, consists of a Cooling Tube, Heatsink, and Fan Assembly.

The Cooling Tube is a slightly flattened copper tube, filled with Nitrogen, and sealed on both ends.

Scroll down to Step 5, a).

The copper curved tube you see is the Cooling Tube. Along most of the length of the Cooling Tube, is an aluminum plate.

At the other end of the Cooling Tube is attached a Heatsink.
This is the rectangular Black finned object, you see at the top of the black Fan Assembly.

The Fan Assembly of course, is the silver looking shroud, with the Black fan in the middle.

Heat is absorbed from the top of the graphics chipset, and Processor, into the aluminum funny shaped plate.
The heat is then absorbed by the Cooling Tube.

The Cooling Tube transfers the heat along up to the Heatsink.
The Heatsink absorbs the heat in the middle, then radiates the heat away through it's Tall, Thin, fins.

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

The rectangular area of aluminum plate, that you see marked off by 4 screws, covers the Processor.

Come up the Cooling Tube a little bit to the left, and you will see a triangle shape meeting a small rectangular shape.
Has one screw hole in it, with no screw.

This small area covers the graphics chipset.

The Processor, and the graphics chipset, are the two hardware components inside a computer, that produce the most heat.

With the cooling surface area of the graphics chipset being inadequate, the graphics chipset overheats.
This can occur for quite a while, then tragedy strikes.

The graphics chipset is mounted to the motherboard, with 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.

The bottom of the Processor has 478 contact pins.
The processor socket has matching socket holes. (478)

With a BGA surface mount there are no contact pins, nor socket holes.

Solder Balls take the place of the contact pins on the graphics chipset.
Copper Pads take the place of the socket holes.
(The pads are usually gold plated)

The graphics chipset is set into place over the motherboard, with the Solder Balls lining up on the matching Copper Pads.
Heat is then 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 solders it to the motherboard)

Excessive heat in long periods can slightly melt, or soften, the solder connections that were made.
This creates a cold solder joint, or joints.

Result is a bad contact of the graphics chipset to the motherboard.

Solution is to remove the motherboard, (Following Anti-Static Precautions), and take it, or send it, to a shop with a BGA Rework Machine.

THIS, is THE proper method.
All other methods are chancy, and you may have the same problem again, REAL soon!

For reference only,

For additional questions please post in a Comment.

Follow the steps below to verify the microphone settings.

  • Right-click the Sound icon in the system taskbar, beside the clock. Select Recording Devices from the drop-down menu.
  • When the Sound window opens to the Recording tab, select Microphone . The Microphone entry should say that it is working, and there should be a meter beside the entry.
  • Tap the plastic above the display gently. The meter should respond to the sound stimulus by rising and falling.
  • If the microphone is not working, or if the meter is not present, or does not seem to respond to sound input, follow the steps below.
    1. Click Properties . The Microphone Properties window opens.
    2. Be sure that the device is enabled in the Device usage drop-down menu on the General tab.
    3. Click the Levels tab. Set the microphone volume to 100.
    4. Click the Advanced tab. Be sure that all of the checkboxes in this window have checks in them.
    5. Click Apply , and then OK . Close the windows.

Error message on dv 1000 pxe-mof and pxe-e61

The error PXE-E61: Media test failure usually means the hard disk has failed or the hard disk needs re-seating or the disk controller is faulty. First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

Hp Pavilion DV 8000 (dv 8113 ea) heats up then hangs & turns off

I believe that would be the battery I would get a new battery that should solve the problem. When you use office or surf the internet that does not require as much power as playing games and watching videos. Just buy a new battery and that should solve the problem

I have a hp pavilion dv 1659 us (dv 1000) the sata drive goes bad

It will recognize the new drive if you were able to "migrate" your data from the old drive. If not, you can clean install by booting from an optical drive (changing your boot order at start-up) and using a new OS disk or your recovery disks. You might be able to perform a remote partition & format and install from one drive to the other with USB external enclosures for each drive and another computer (depending on the 100G drive's condition). I hope this helps.

My frnd has now got his dvd rom replaced for the 15th time within 1 and ha;f year.. so replace ur drive.
