The most common overheating problems that occur with laptops is usually due to a build up of dust in the ventilation grills. This is usually determined because the fan is running constantly.
All you have to do is make sure all the air vents, grills and CPU fan blades are completely free of dust.
Also make sure that the heatsink is sat level on the processor itself as an unbalanced heatsink will certainly cause the laptop to overheat.

My computer will keep cutting off it mainly do it when im on netflix i thinking it got somethin to do with my shockwave

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Dell laptop inspiron m5010 screen shows 3 images across - external shows the same

This = Not good

Graphics chipset problem.

A) Graphics chipset is overheating.

1) Suggest clean inside of laptop out,

2) Apply new Thermal Paste to CPU, (Processor), and also carefully peel off the Thermal Pad on graphics chipset, and throw away.

Suggest this time instead of using a Thermal Pad again, (Shudder), use a piece of copper sheet that is the correct thickness, and surface area.

Then use Thermal Paste on top if the graphics chipset, and top of copper sheet; before reinstalling Cooling Tube/Heatsink combo.

B) Graphics chipset has overheated, or actually has been overheating; and has now caused a poor contact of graphics chipset; TO motherboard.

Allow me to expand on A and B above.........

First of I think the graphics chipset is bad?
No sir, I do not.
Proof is that you ARE getting graphics on the LCD screen.
Three images, or not.
(Internal monitor of laptop, OR external monitor)

Referring back to A)

The CPU (Processor) and the graphics chipset, are the two hardware components that give off the MOST heat.

If the laptop is dirty inside, the cooling capacity of the cooling system; has dropped tremendously.

This allows the CPU, and the graphics chipset (GPU), to overheat.
Overheating graphics chipset will do all kinds of strange things.

What also transpires, is the Thermal Paste dries up.
Looses it's thermal conductivity properties.
A Thermal Pad is a material that is impregnated with Thermal Paste, so you can see how this equates.
It's impregnated Thermal Paste also dries up.

To regress;
The top of a Processor (CPU), and the bottom of the metal plate of the Cooling Tube, that sits on it; are not perfectly smooth.

A magnified view would detail, 'Ridges, Valleys, and Pitholes'.
When the two parts are mated together, Air Pockets are formed.
Air in this case is an Insulator. Not a Conductor.

Thermal Paste fills the above imperfections, and is an Excellent conductor of heat.

Moving on.........

A Thermal Pad is J-U-N-K!
Carefully peel off, and fly it at the cat. (NO, don't! lol!)

Using a small piece of copper sheet, that is the correct thickness; (And width/length), will allow more surface area for cooling. Becomes more passive surface area for cooling.

(The Fan Assembly does not blo-w air on the graphics chipset. More on that in a moment. Therefore it would not be Dynamic cooling. It is Passive cooling )

Let's take a look at the cooling system for the Dell Inspiron M5010, and I feel it will help explain better........

Scroll down to the three large photos.
The top, or first photo; shows a Top view.
The next photo down shows a Bottom view.
The photo below it shows a detailed view of the finned Heatsink.

Looking at the first photo, or can be said - Top View.....
The black Fan Assembly is at the top.

Note the rectangular area to the Right, of the black Fan Assembly.
This is the Heatsink.

Coming down from it is the curved copper Cooling Tube.
Note the small rectangular copper metal plate, then at the bottom of the Cooling Tube; note the V-shaped Aluminum metal plate.
(V-shape that goes to an odd shape)

Cooling Tube:
Sightly flattened copper tube, sealed on both ends; and filled with Nitrogen.

Has a small rectangular copper metal plate, that sits on the graphics chipset.
Also has an Aluminum metal plate (V-shaped), that sits on the CPU.

Small piece of aluminum strip, that has Tall, Thin, fins protruding from it, and is rectangular in shape.

Fan Assembly:
Small multi-bladed fan, in a D-shaped shroud.

Working principle:
Heat is absorbed from the Processor, and graphics chipset, by their two respective metal plates.
Then the Cooling Tube absorbs heat from the plates.

The Cooling Tube then transfers the heat to the finned Heatsink.
The Heatsink absorbs the heat, then radiates it away with it's tall, thin, fins.
Air flow from the Fan Assembly, helps carry heat away from the Heatsink's fins.

That small rectangular piece of copper plate, that sits on the graphics chipset; it TOO SMALL in surface area.
The surface area needs to be increased.

This would be accomplished by ADDING a small piece of copper sheet, that is larger in surface area; and is of the correct thickness.
(Approximately 1/16th of an Inch thick, or 2mm)

Using this video to help explain adding more surface area,

Posted for added surface area, NOT re-flowing graphics chipset, BGA surface mount.
Specifically go to -> 08:38

You can get a small piece of copper sheet, from a hobby store.
Thermal Paste is used on TOP of the graphics chipset, AND on top of the small copper piece of metal. Then the Cooling Tube is installed in place.

For additional questions on this procedure, or to have me clarify anything I have stated, please post in a Comment.

Moving on in an added Comment.

Cpu fan running at full speed

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

desktop or laptop computer fail to boot for a variety of reasons, but a fast, loud fan noise signifies that the system is suffering from overheating.

The problem, and the steps for troubleshooting it, is not unique to the Gateway Desktops.
When the internal temperature of the computer reaches too high a level, the system will shut down automatically to allow the heat to dissipate.

If you attempt to power up too soon, the machine will not boot properly.

To boot, you will need to correct the cause of the overheating, and keep the machine cool.

Blocked Vents

Although different in size, both desktop and laptop computers have air vents to help the fans keep air circulating around the hot internal components.

If these vents become blocked, by pushing a desktop too near a wall or using the laptop on a soft surface, the air supply your internal fans need to cool the system is cut off.

This blockage also traps the heat inside, allowing it to build to dangerous levels.

Keep the air vents on your computer free and clear to allow proper airflow.

Dirty Computer

Airborne particles, such as dust, lint and hair, can gather on the air vents and internal components over the course of time.

This accumulation of dirt not only provides a sort of "insulation" to the electronic components, preventing the heat they generate from dissipating normally, but it also clogs the fan and heat sink to prevent proper function.

Use canned air and damp, soft cloths to thoroughly remove any built-up debris from inside your computer.

Dried Thermal Paste

The heat sink sits atop the CPU chip to help dissipate the heat the component produces. Thermal paste is layered between the CPU and the heat sink to help draw the heat away from the chip for cooling.

Over time, the cooling properties of this paste decreases, and the substance becomes dry and flaky.

You can replace this paste to renew its cooling assistance by removing the old paste remnants with rubbing alcohol and adding a new layer.

Thermal paste is also known as thermal compound or thermal grease, and is available at most electronics stores.
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.

Hot Environment

When examining overheating causes, don't overlook the environment you use your computer in.

External heat sources, such as fireplaces or even rays of direct sunlight, can cause the internal temperatures of your computer to rise.

This causes your internal fan to run harder in an attempt to dissipate the combined heat before temperatures rise too high.

Move your computer away from external heat sources to encourage more effective cooling.

Hope this helps.

I've a Medion Akoya, it keeps running hot till it freezes

What happens if you just use the power cord without the battery being in the laptop?

Three things that will cause a laptop to overheat:

1) Dust - Dust inside the laptop, dust clogging the vents and fans, dust around the cpu and heatsink. Remedy - take the laptop apart and blow out the dust with a can of compressed air.

2) A Fan not working - Remedy- Replace the fan.

3) The Thermal Paste on the cpu and heatsink has either dried up or is too thin to keep the unit cool. Remedy - Apply a fresh coat of Thermal Paste to the CPU and Heat Sink.

You could try a Laptop Cooling Pad which has fans on it and the laptop sits on it to keep cool. It plugs into the laptops usb port. Try Tiger Direct at:

When the site comes up just type: Laptop Cooling Pad in the white search box at the top of the website then press GO. Sort the returned results by Price Low to High

Below is a link to one I use most times for people experiencing overheating issues but can't afford the expense of going inside the laptop. $12.99

Computer keeps shutting down. It will start up and sometimes work for a while then shut down unpromted. Or if I start it, the computer will just keep shutting down and restarting for no reason. I can get...

That sounds like either a graphics problem or more likely a memory problem. Try taking out a couple sticks of RAM or leave just one in and try that.

The overheating fan is not controlled by a software, there are three reasons why your fan overheats. First in the hard drive, your fan is not connected properly. Second you need thermal paste to keep the metal part of the fan to stick to the CPU to cool it down. The last thing is that the fan could be dusty and not running as usual.
