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

Can I get the directions on the disc replacement

It really simple. First, you need the replacement disc. I have one extra that I purchased on ebay. You will need I screw driver called torx to remove stews on rear of unit. Once you remove cover, remove fans from heat sink (fined structure.) Now, locate wire connector on mother board for heat sink and disconnect. With a phillips screwdriver, remove four screws holding sink to unit. Remove heat sink being careful to route wires and connector out of passage way in cabinet. Use your camera phone to take pictures of the unit each step of the way in case you forget how to reassemble. Next, remove the four screws from the smaller square heat sink that was facing inward in unit (cooling side.) These screws may have sealant covering the phillips heads. Separate the two heat sinks and you will see the cooling disc saneiched between. You will have to cut the wires on the old disc to save the white connector to the mother board. Cut, splice, and solder the new disceires to the connector you saved. Replace everything and that's it. Mine works great.

Hey man, I saw a previous post where you were the only person to help the customer out. Probably pretty easy question, but my heat sink retention bracket for the CPU broke. It is an HP pavilion 514n. ...

I'd suggest release the other side and remove the fan & heat sink. They often come as a unit. Its very common to buy a new fan and the heat sink comes with it. It really depends on what processor your using. Its getting hard to find pent 3 stuff but otherwise you should be able to find another heat sink or fan, or combo with both and the bracket to fasten it is part of the heatsink fan assembly. Take the whole assembly to your local computer geek shop. They'll have another one.OR have a bones system they'll borrow from. You should find it on-line somewhere, but it would take awhile to find one. If you can carry in to a shop you'll be more likely to leave with the right thing. You might be able to rig it with something, but with the much heat around it and voltage being so close it wouldnt be a very good choice. I had one that broke one and then a little piece started rubbing the fan and making noise. I think the heat is what made the plastic so brittle and why it just broke.

Power will only stay 0n for a few sec and then shuts off

Hi,the problem with your ps3 is a heat sync failure,it's a common problem with the ps3,however,here is a detailed solution to help you out;

You have to disassemble the ps3 first, (hint) there is a srew were your rubber boot is on the bottom were it stands up remove this srew but you my have to get a star bit with a hole in the center of it. 2. After removing the cover then sides to the screw,lift the cover to remove all visible screws in the second cover.
3. Lift the second cover in a hinged motion to the front of the ps3 be careful not to pull the hidden carbon wire underneath of the cover if done properly you will see the wire when you lift the cover. To release the wire you must lift gently on the black clip holding it and it will release with no problem.
4. You then lift the blue ray drive up and then dissconnect the wires to it. then remove the power pack which is to the left of the blue ray drive remember there are screws holding this down, remove the wires then remove this peice as well, then remove any remaining screws on the mother board cover except the large philip head screws holding the clips that are in a slant. lift the mother board out to reveil the fan on the bottom now remove the srews that are slanted. the fan will then seperat from the mother board. then clean both of the contacts on the mother board and fan with rubbing alcohol. then seperate the metal from the mother board.
attention; there will be a watch battery connected to the metal,disconnect from the mother board. gently lift up on the metal to seperate the mother board from the metal. At this point you must be extra careful not to move any of the parts on the mother board remove the rubber peices then cover the heat syncs so they dont melt use a heat gun that can reach a temp. of 350 degrees Cel heat for 15 sec on the three heat sinks with a distance of 1 inch or greater move the heat gun counter clockwise on the sensors. during this time the peice must be level or it will hurt the system. After heated you will then need to let cool for 15 min. then flip the board over and hit the exact same spots in the same steps. at this point your problem is solved. Make sure all the peices of rubber that was on the chips is put back in the right spots too.You then put the metal back on the systems mother board at this point clean the syncs again then apply the artic silver in a thin bead on two heat syncs note not too much and not to little just enough to cover the syncs with a thin coat then connect to the fan. reconnect the fan then put the screws back in that holds them together then reattach the power supply but dont srew it down then remove the srews on the fan moter then remove it plug in your system switch it on stand by then press the sensor pad metal to start the system note this will not hurt your system this causes the artic silver to soder the heat syncs together only do this till you see a orange light come from the board near the fan then shut the system down then reattach the fan and reassemble.
Take care

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.

How to remove the cooling fan

They are usually mounted on with plastic clips, sometimes with screws. Use a small screw driver to loosen the clips on all the sides at the same time so the fan can some off.
