1) If the laptop is dirty inside that will sure do it.
If to your knowledge the laptop has never been cleaned inside, then it is.
The Processor and graphics chipset, are the two hardware components that give off the most heat.
Example of a laptop that is dirty inside.
Dell XPS M1710 used for example,

Better idea of what you are looking at,

Click on image to enlarge.
1) To the left you see the rectangular finned Heatsink.
2) The curved copper Cooling Tube
3) The aluminum metal X-shaped plate, that sits on the CPU (Processor)
4) The small square shaped aluminum metal plate, that sits on the GPU.
(Graphics chipset - slang, proper term - Graphics Processing Unit;
http://en.wikipedia.org/wiki/GPU )
The narrator in the video is removing a 'lint blanket', from the fins of the Heatsink.
The Cooling Tube is a slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.
The aluminum metal plates that sit on the CPU and GPU, absorb heat from them.
The Cooling Tube absorbs the heat, then transfers it up 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 fins of the Heatsink.
Example of Fan Assembly,
http://www.parts-people.com/index.php?action=item&id=3059
The side on the right, goes against the finned Heatsink.
Air is drawn up through the center, then comes out the straight side of that D-shaped fan shroud.
Fan in photo is clocked 90 degrees to the Right, to how it actually sits on the laptop.
When the GPU (Graphics chipset), overheats; videos and frame rates seriously slow down.
When a CPU (Processor) overheats it turns off. (BIOS turns it off)
This is a fail safe feature built-in. Keeps the CPU from burning up.
ALSO;
Thermal Paste, or a Thermal Pad is used for the CPU, and GPU.
Generally the CPU uses Thermal Paste, but not always the case.
Thermal Pads are used too.
Most of the time a Thermal Pad is used on the GPU.
The top of a Processor, and the top of a Graphics chipset, are NOT perfectly smooth.
A magnified view would detail, 'Hills, Valleys, and Pitholes'.
Same thing with the bottom of the two aluminum metal plates, that sit on the CPU, and GPU.
Mated together there are air pockets that are created.
Air is an Insulator. Thermal Paste is a Conductor.
Excellent conductor of heat, and fills the above stated imperfections.
A Thermal Pad is a material that is impregnated with Thermal Paste.
(Usual size about 1 Inch by 1 Inch, and 1/16th Inch thick.
[25.4mm by 24.5mm, and 1.524mm thick]
If a Thermal Pad is used, carefully peel it off, throw away.
They're junk, and can't be reused anyway.
Most of the time however, they are needed for the GPU.
The distance between the top of the GPU, and the metal plate on the Cooling Tube; requires this thickness.
NOT this kid.
I find a suitable small piece of copper sheet, and the correct thickness. Then I apply Thermal Paste (PROPERLY), to the top of the GPU, and the bottom of the metal plate.
I also use a piece large enough so that more heat is dissipated, then with that small square of aluminum. (That sits on the GPU)
More surface area = better heat dissipation.
!O_O!
Observe what this tech has done, as far as increasing surface area; and you'll know what I mean,

State the model number of the Acer laptop in a Coment.
This is on the bottom of the laptop.
Perhaps I can find a link to a free Service Manual, and maybe a pictorial disassembly guide.
I can also guide you if you wish.
2) If it's videos on the internet, make sure your Java is up to date, and your Adobe Flash Player.
If you stated your laptop just stalled on certain intense games, I would have stated your GPU isn't good enough to run them.
Post back in a Comment.

Open the Task Manager, click on the Performance tab, is your CPU running at or near 100% while the Media Player is playing the video? If so, you may have to many open/running programs. Running a Media Player requires more Processor and Memory. What Media Player are you using? Are you viewing the video on-line? You didn't supply the Acer model or the OS you are using?
