In general there are many things that cause the computer to be overheating alias too hot, here are some of the causes and solutions to solve.
1. Computers are used to play the game too long. To play games especially with high-resolution images, needed 3 component of the heavy work of processor, memory and VGA. Processor working too hard will cause high heat and may cause the computer immediately turns itself off. Prevent it, you can add a suction fan at the back of the CPU to suck hot air from inside.
2. Note the processor. There is a difference between AMD processor with Intel. Intel's latest processor allows only heat up to 72oC to 85oC while AMD can be no significant difference when touched by hand. But if this hot issue then cause the computer to become slow or die alone then be a problem.
3. Cooling fan is damaged or dirty areas. If the fan speed is decreased or very dusty, the cooling air supply will also decrease so that the processor be overheating. How to prevent it, you can open a cooling fan, clean the dust and make sure that the fan is still spinning with the normal, or if it has been known to corrupt, then replaced it.
4. BIOS overclock. BIOS overclocking or performance graphics card, CPU, motherboard, RAM and all the components inside the CPU casing is made maximum, can cause the computer to heat or, worse, could cause the computer not work at all. Prevent it, if overclocking is the cause, return the BIOS back to its normal position.
5. Power Suply problem. If a leak on Power Suply, then the voltage out to motherboard and to all electrical components of the CPU to be hot, or a number of components damaged directly. Prevent this, use Stabilizator bias or UPS to maintain voltage.
6. Position Aluminum heatsink (cooling) is not appropriate. If aluminum is not attached properly to the body of the processor, the processor can easily overheat and then the computer would die alone. Prevent, if possible you can do it, be careful when opening the fan over the processor and check if the aluminum heatsink attached properly to the processor. If necessary, open the refrigerator and clean the aluminum surface of the paste on the processor surface and rub back the new pasta.
7. Aluminum heatsink (cooler) processor or on the VGA dusty / dirty. Ensure sufficient cooling aluminum dust because dust can inhibit the process of cooling fan. How to clean the processor cooling fan once every 6 months.
