Cpu not getting started



Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty


make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty


computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error


even something as small as a faulty electrical or fan lead can cause you problems



motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail



check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working



also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in


check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.


Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

hope this helps

Electrostatic Discharge (ESD) can kill your computer

ESD can permanently damage your laptop. Always ware ESD wrist strap when you work with internal computer components.

How notebook screws are marked


In Toshiba notebooks most screws are marked. Here are some examples:
F4 - flat-head screw 4mm long
B6 - button-head screw 6mm long
F16 - flat-head screw 16mm long
B8 - button-head screw 8mm long

When you are taking apart a laptop you'll have to deal with lots of screws. Keep everything organized.


Removing Memory Modules


Carefully spread latches on both sides of the memory slot with your fingers.


Carefully spread latches on both sides of the memory slot with your fingers.


Carefully pull the memory module from the slot by the edges.


Removing Wireless Card

There are two antenna wires connected to the wireless card.
White wire connects to the main connector on the card.
Black wire connects to the auxiliary connector on the card.

To disconnect the antenna wire from the wireless card grasp the connector with your fingers and unsnap it from the card.

Carefully spread latches on both sides of the wireless card slot, just enough to release the card.


The wireless card will pop up at 30 degrees angle.

Pull the wireless card from the slot by the edges.


Disconnecting Keyboard


Before you pull the keyboard cable from the connector on the motherboard, you'll have to open up the connector.

Before you pull the keyboard cable from the connector on the motherboard, you'll have to open up the connector.

After the connector is unlocked you can pull the cable. Be very careful with the connector. If you accidentally damage the connector, you'll have to replace the motherboard.

Removing Modem Card

The connector is located under the modem and you cannot see it until the modem is remove. After the modem is removed, disconnect the cable (on the left side).

\Usually the modem is secured to the motherboard by two screws. Remove them.

To disconnect the modem from the motherboard lift it up.


CPU came out attached to heatsink
In some cases, when you remove the heat sink, the CPU might get out attached to the heat sink. DO NOT install it back into the socket like that, separate the CPU from the heat sink first.


CPU came out attached to the heat sink because thermal paste dried out and glued the processor.

Insert a flathead screwdriver between the CPU and the heat sink surface. Carefully rotate the screwdriver until the CPU separates from the heat sink.

\Lift up the CPU and install it back into the socket on the motherboard. Now you can safely remove old thermal paste and apply a new layer of paste.


Removing and Installing CPU


The CPU is locked in the socket. Before you can remove the CPU, you'll have to unlock the socket. Use a flathead screwdriver and turn the socket screw to "Open" position.


Lift up the CPU by the edges. Be careful, there are a lot of fragile pins on the opposite side of the CPU. You should be able to install the CPU back into the socket without any force.

There is only one correct way to install the processor into the socket. Both CPU and socket are keyed. When you are installing the CPU, make sure to match pins on the processor with holes on the socket.

Before applying thermal grease on the CPU, clean the surface with alcohol.

After the CPU surface is cleaned, apply a small drop of thermal grease.

Spread thermal grease evenly and install the heat sink.


ATTENTION! If you forget to lock the CPU in the socket, the laptop will not boot. If you install the heat sink without applying thermal grease, the CPU will overheat.

When I was turning on my laptop after 5 mins. my laptop turning off on its self. I need your advice solution.


When the laptop shuts down and you can't boot up until it has cooled down, then your notebook could have an overheating problem. The CPU shuts down when it overheats (thermal shutdown) and if this problem is not fixed the the CPU will eventually fail.
The overheating problem could be caused by a faulty CPU fan or the fan and hear sink assembly is clogged with dust.
Check the CPU fan and if is does not spin freely then it needs to be replaced. If the fan and heat sink is clogged with dust, then remove the dust, you can also use a can of compressed air to clear the dust from the heat sink fins.

Computer shuts down by itself


There can be many reasons of unexpected shut down of your system.Below are some remedies to solve it

1
Run an anti-spy ware and anti-virus utility to make sure that the shutdowns aren't being caused by a malicious program. If the shutdowns are infrequent, install a CPU temperature monitor utility to keep track of the CPU's temperature. If the CPU is overheating, or the shutdowns are frequent, then you will need to troubleshoot your computer's internal components.

2
Check any recently installed internal components to ensure that they are properly connected to the computer's motherboard. Make sure any new expansion cards or memory modules are securely seated in their slots, and ensure that the power and data cables are properly connected to any new drives.

3
Check for large dust buildups on your CPU fan. If the fan isn't effectively cooling your CPU, the overheating CPU will cause your computer to power off. Carefully pick away large pieces of dust with your fingers, and then spray the CPU fan with a can of compressed air to remove the rest of the dust.

4
Reapply the heat sink compound between the CPU and heat sink if the computer continues to turn off unexpectedly. Heat sink compound is a pasty substance that fills the space between the heat sink and processor, which increases the heat sink's ability to absorb heat from the CPU. But worn heat sink compound won't properly redirect heat away from the CPU. Power down your computer, disconnect its power cables and open the case. Unplug the CPU fan's power cable from the motherboard, remove the heat sink and fan combination from the CPU, and then apply the heat sink compound to the CPU--refer to your product manuals for details on reapplying heat sink compound.

Thanks .
Have a great day.

Laptop won't boot turns on then off after about


Hello,

Your Laptop seems to be full of dust - Maybe your CPU Heat sink FAN cannot turn because if this THUS causing your laptop to heat up and shut down again to prevent your CPU from receiving damage due to high temperature.

Close your laptop lid, then put the unit on its backlcd. Make sure you disconnect the Battery and the A/C Power chord. With the emty battery slot is facing you, take note of the screw that is facing you to the right on the bottom cover. There might be others like this in the same area. The cover that you need to remove is of rectangular shape, and the largest cover.

When you have removed it you should see the CPU Heat sink and a FAN. This is the part where you blow the unit out at that spot with compressed air so that the dirt will no longer block the heat from venting away from the laptop mainboard/cpu.Please check if the CPU FAN is still turning licenly. If it doesn't turn or very difficult - replace .

[ADVANCED]
Then, remove the 3 screws from the CPU heat sink and thereby remove the HEAT sink completely. Remove the CPU Heat sink FAN and clean it as nessesary. Use a small flat to switch the CPU from closed to open and remove it. Then clean it with a cloth and ethanol - make sure you remove all dirt and old heat sink paste on top if it. make sure you do not touch the bottom of the CPU and handle the pins carefully.

When you are done, place the CPU back and reaaply a eyedrop of fresh heatsink paste onto the CPU, lock the CPU switch again. Then clean the backside of the CPU heat sink where it rests on the CPU. When you are done with that, place the CPU heat sink back onto the CPU then screw the 3 screws back onto the CPU heat sink and onto the mainboard. Keep the sequence in mind. Reconnect the CPU Heat sink FAN to power on the mainboard with the cable then place the cover back onto it. Tighten all screws again and reconnect battery and A/C Power chord.

Is my cpu getting to hot my cpu fan runs in high speed a lot. do i need a bigger fan or my cpu is going bad.


Neither.

Turn the computer off.
If it is a HP laptop, remove the battery.
Disconnect the AC power.

Buy a can of compressed air, and give your computer a "blow-job",
to blow all the dust away from the heat-sink on top of the CPU,
and also, if it is a desktop, from inside the power-supply.

A layer of dust is a layer of insulation, preventing the heat-sink on top of the CPU from "radiating" the heat away from the CPU. So, your motherboard is detecting that your CPU is "too hot", and automatically speeds-up the cooling fan, to try to move the heat.

Fails to boot, fans and lights on, no bios or anything


My recommendations would be to remove all connections to the board.
Remove the CMOS battery.
Remove the CPU fan and CPU.
Look at the top of the CPU, if you have a crust over the top of the CPU, you will need to remove it to a clean surface.
Next, your CPU fan should be a 3 wire connection on the motherboard, within two inchs of the CPU holder.
After cleaning the CPU, re-inseart and apply a heat sink lub for good heat transfer.
Re-install CPU fan and plug in to board connection.
Re-install your CMOS battery and power up unit.

With the CMOS battery removed, the time and date will need to be reset.
Also, in the BIOS for that board, you should be able to see temps. and rpm readings. ??
Hope the CPU has not taken a dump on you.!
Before you plug in the drives and other devices, check temps. rpm and voltages.
Have fun, hope this has helped you.

Hi Donna,
I'm not asking you to unplug the CPU's fan while the system is running!
(That would be a bad idea & the system would over-heat for sure).
The fact that you are not able to enter the bios is a major factor & you should have posted this.

So far this is what I do know. Memory was added to the system.
You can not enter the motherboards bios menu. Your old CPU fan was running at 1713Rpm, temp 46C which is, 114.8 Fahrenheit & you cleaned the CPU fan & assembly.
Than remove the heat-sink & fan assembly & applied new thermal grease.
(Guess the video's helped)?
Now tell me. Did the problem - (System restarts), did this start happening shortly after you added new memory onto the motherboard?
This is what I want you to do. Gather up a couple cotton swabs & a bottle of house hold alcohol. Unplug the power cord from the PC. Open your case. There are two memory slots on the board. You said you added memory 2 years ago. Carefully remove the memory from their slots. Look to pages 102-104 in your user manual for instruction on how to remove & install your memory. If you no longer have your user manual you can download it & print it out from this link: http://h10032.www1.hp.com/ctg/Manual/bpb13287.pdf
You will also need Adobe PDF reader to view the manual, which can be download for free at Adobe's web site: http://www.adobe.com/products/reader/

Once the memory has been removed take a cotton swab & place a couple drops of alcohol on it.
(Not dripping wet). Wipe the memory’s contacts/ each side both sticks. (Do not touch the contacts with your fingers). Use canned air & blow the memory slots out. If you do not have canned air you can use a powered sweeper with the brush attachment to clean the memory slots out. Than re-insert both DIMMs back into their slots. (Press firmly down while "slightly" rocking the memory left to right as you push down until both locking ends snap onto the memory). Before you close the case, I want you to check every connection in the case. Any one data cable or power cable could be loose.
If in doubt of a solid connection, unplug & re-connect carefully but firmly.
I'm pretty sure your system is not restarting because of the CPU but rather a loose connection or dusty / dirty memory, poor connection & bad or too weak of a battery. Normally I would suggest clearing the cmos/bios jumper on the board but Compaq does not provide the motherboard layout in the user guide. The battery on the board. Is about the size of a quarter. The average battery life is five years. This Compaq was built Aug-2003. One can remove it & check its voltage with a volt meter. It should hold 3volts DC. You can buy a replacement online or ask a friend that owns a volt meter to check the battery. Here is a picture of the battery:
8ee2615.gif

When finished, close the case & plug the power cord in.
That second fan in the system is not connected to the board & that is why there is no speed reading coming up with the software you installed. (This is ok). (Use a small clean paint brush to wipe the fans blades from dust build up, (both sides).
I'll provide Compaq's link for your Presario S5000NX DM171A. (Drivers & software):
http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&cc=us&dlc=en&product=359576&lang=en
Never know when you might need a driver.
Need to buy a battery:
http://www.amazon.com/Energizer-Watch-Electronic-Batteries-batteries/dp/B0002DSVTC/ref=pd_sim_e_6/192-5794784-5234322

Well this should fix the re-start issue. Take your time.

Post if the problem persist........

Good luck Donna!
Mike
