Bad processor on my hp compaq

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. - rules

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.

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

F06 error code. Its not what you think

Had F06 error usually when the washer went into spin cycle. Followed all tips on different sights. No real concrete solutions to my problem. Sense my problem was intermittent I ruled out the motor. I started looking at my MCU and found my heat sink was really hot to the touch. I slipped MCU out of wash machine still electrically connected and put my window fan on MCU while operating and washer worked perfectly. I the went down to Radio Shack and picked up a 115v CPU fan ($20) and installed on my heat sink. Just splice fan wires to MCU power wires (wire connector w/ the 2 largest pink wires). Mount fan creatively to heat sink (tywraps, hot glue gun, however) . I saved $150 and the heartache down the road. I think this a common problem for that MCU. Hope this helped. <br /> Robert, Aircraft Technician

3 of 4 rings were red, now no lights at all

ok the three red rings was lit to notify you that your board, cpu and gpu have experienced a significant source of heat. So much in fact you really should bring it to a repair shop. I see these at least 4-5 times a day your 360 needs to be disassembled and the heat sinks removed this will allow you access to the cpu and gpu both sides of the board need to be heated with a equal amount of heat to heat up the solder and reseat both chips.

Sonix lcd tv 27lc 27m6s regular horizontal flashes/lines. looks like reception is,

Here is what you do, Open the back cover. Check the heat sink by tweaking it around. Get a small fan which is usually the size of fan over the processor in the desktop PC. connect the positive and negative wire of the fan from the power supply lines within the tv use nearly 3.3v line. now place the fan in the top corner of the tv near the heat sink for the cooling purposes. fix the fan with tape or glue so that you can easily close the back cover.

Where can I get a replacement cooling fan an NVidia Quadro4 750

I had a problem with the fan/heat sink assembly on an nVidia GeForce 5500 FX card a year ago. The card was in a multimedia computer and had lots of running hours on the fan, and the fan's sleeve bearings were shot, causing it to rattle. Failure of the fan seemed imminent, and before it did so and damaged the GPU chip on the card, I decided to fix it. Unfortunately, nVidia had used many different styles of fan/heat sink assemblies on this product, all of which were apparently obsolete. On closer inspection, however, one could see that the original fan on the chip cooler assembly was the core from a Sunon KD1204PFB1 12VDC/1.4W 40mm sleeve bearing brushless tubeaxial fan. One could also clearly see where the three struts were cut to remove the fan from its rectangular housing. The fan was glued to a clear plastic 3-tab mounting "spider", which, in turn, was attached to the heat sink with three small screws.

Here's what I did to fix mine; perhaps a similar approach will work for you.

1. Remove the video card from the computer.

2. Unplug the fan connector. On some cards the fan is plugged into a 2-pin header on the card, while on others it is connected to +12V via a Molex-type disk drive supply tap.

3. Remove three small flat head Phillips screws and lift fan assembly off heat sink. You will need a #0 Phillips driver or small jeweler-type crosspoint driver. DON'T LOSE THE SCREWS!

4. Very carefully pry fan from the clear plastic mounting spider. Most likely, it has been secured in the factory with some type of cyanoacrylate adhesive, i.e., "Crazy Glue". Take care not to crack the spider, as you will need to reuse it. It is better to peel the label off the back of the fan motor, than try to get the entire fan assembly off at once.

5. Clean up cyanoacrylate glue residue from spider by carefully grinding with an elliptical or spherical burr in a Dremel tool, to produce a flat surface.

6. Get a similar replacement fan. In this case we'll use a Sunon KDE1204PFVX 12VDC/1.9W 9.5CFM, 40x40x10mm MagLev bearing fan. (Ordered from Jameco Electronics, Belmont, California, about $7+tax & shipping. It costs about $2 more than the sleeve bearing OEM equivalent, but the MagLev bearings should outlast the computer by decades.) Cut the fan core out of the duct housing in a similar fashion to the original. Be careful not to snip the wires.

7. Align the fan motor cable with the cable guide tab on the spider, to route the cable away from the hub and keep it out of the fan blades.

8. Use a small blob of hot-melt glue to secure the fan onto the plastic spider. Press the fan gently against the spider until the glue solidifies, between your thumb and index finger.

9. Install the motor assembly on the heat sink with the three small screws. Route the motor cable between the heat sink fins as before. (The original cable had electrical tape wrapped around it where it passed between the fins, but I deemed it unnecessary to duplicate this. If the chip were to get too hot, it would probably cause the hot melt glue to fail, as well as cook the PC board anyway. In normal operation the heat sink fins stay close to room temperature.)

10. Connect the motor wires to the original connector, matching wire colors. (red = +12V, black = ground) If connecting to a Molex-type disk drive power tap, note that +12V is on the yellow wire.

11. Reinstall the card in the computer, connect the fan to the power supply, and power it up to verify that it spins. If everything looks good, button up the computer and you're done.

Heat sink fell off processor

Go to your local Staple,Radio Shack or Best Buy and get a new heat sink and fan assembly, if you are lucky it will thread through the motherboard so you can reset it onto the processor chip. DO NOT PUT SUPERGLUE ON THE PROCESSOR.

K8S-LA mobo heat sink fell off.

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.

Alert chipset heat sink not detected system halted error message

This is a relatively common problem in the Dimension 4600c. The small, fan-less heatsink for the Northbridge chip (a memory/video-to-cpu communications chip) is held down by a spring, which is anchored by two small wire loops soldered to the motherboard at locations marked "HS2". The spring completes an electrical circuit between the two wire loops. The spring puts a substantial force on the minscule bit of solder holding the loops to the motherboard, and was a poor design.

If a loop breaks off, the circuit is broken, which tells the BIOS that the heatsink fell off. To fix this, you need to 1) secure the heatsink to the chip, and 2) reconnect the circuit between the two "HS2" locations on the motherboard. I have sucessfully used this solution. This solution will not necessarly stand up to a lot of abuse if the Dimension's enclosure is frequently opened and closed to replace other components such as RAM and hard disks.

0) unplug the computer.

1a) Recover the heatsink, spring, and loose wire loop. Discard the spring. Get:
- a fresh tube of thermal paste from Radio Shack or other electronics supply store,
- some epoxy,
- a round toothpick,
- about six inches of insulated 14 to 20 gauge solid copper wire,
- electrical solder, flux, and a soldering iron,
- and a box of cotton swabs.

1b) Using pure alcohol and lots of cotton swabs, clean *all* of the existing thermal paste off of the Northbridge chip and the bottom of the heatsink. When both are dry, apply a dab of paste to the center of the Northbridge chip. Use a round toothpick like a kitchen roller to spread the paste evenly across the small raised center square of the chip.

1c) Apply small daps of mixed epoxy just outside of the four corners of the raised center of the Northbridge chip. Place the heatsink onto the Northbridge chip, centering and squaring it as best you can. Press firmly to make good contact with the thermal paste. Allow epoxy to dry.

2a) Firmly seat one or both detached wire loops into their mounting holes at the "HS2" locations. While pressing down on the loop, apply a small dab of epoxy to one end of the loop to secure it to the motherboard. Allow epoxy to dry.

2b) Strip the ends of the copper wire, and bend the wire so that it can reach around (rather than over) the heatsink to the two wire loops. Solder the ends of the wire to each loop. Knowing how to solder is an exercise left to the reader. "Use head main ting": don't drip solder onto the motherboard.

You can now plug in the computer and restart. The BIOS and/or OS may have saved the error state and return a different message about the heatsink issue. You may need to reboot a couple of times to allow the BIOS to notice that the "HS2" circuit is (hopefully) now complete. When you've sucessfully booted the machine, shut it down and gently close the Dimension's enclosure.
