Have ever you had situation where your laptop or  computer is unusually hot and sometimes turn itself off?  Then you’re not alone since chances are many computers owners may have similar situation

Why are computers too hot and turn itself off? Generally speaking there are various  factors that cause computers to overheat. These can be due to both hardware failure and incompatible drivers or software as well as the result of wrong computer settings.

Computers that shut itself down may be  the result of  not only overheating but several factors may also play a role such as damaged memory, driver or software incompatibility, hardware conflict and virus or spyware infections. It is highly recommended that you install application that monitor you computer performance such as, fan speed, CPU temperature etc

Before we proceed, first of all you must take a look at the following facts: different processors have different maximum tolerable computer or CPU temperature range. AMD-powered computers’ maximum tolerable temperature range is 85oC  whilst those running the latest  Intel processors is 72oC.

Below are a list of major causes that make your  computer to overheat:

  1. Wrong BIOS settings. If you perform BIOS  overclok you might run a risk of making  your computer too hot even in the worst scenario you can cause the computer not functioning at all. The only solution to this problem is to revert back the  default BIOS settings.
  2. You’re an avid gamers and you use your computers to play resources-hungry games. These type of games eat into your memory resources, processors and VGA hardware. In this case you get your computer processor to work extra hard. This will result in computer overheating and if your processor is not able to handle it anymore your computer will turn itself off immediately. The solution : add the suction fan at the back of the CPU to suck hot air from inside of the CPU
  3. Damaged or dirty cooling fan. If the coolling fan speed decreases or is  very dusty, the cooling air it suplies the CPU will also decrease resulting in hot or overheating processor. How to get aroung this? open the cooling fan, clean the dust and make sure that the fan is still spinning normally. Faulty or damaged cooling fan should be replaced with a new one.
  4. Power supply leakage. This will result in significant increases in the voltage output to the mainboard and other components. The unusually high voltage will cause electrical components of the CPU to overheat or even damaged. To resolve this problem you’re recommended to use stabilizer to keep the voltage stable.
  5. Dusty or dirty aluminum heatsink/  processor or the VGA cooler). If the cooling fan is just fine, make sure that the aluminum coolant is clean and  dust-free because dust can inhibit the cooling process supplied  by a fan. Solution; Clean  heatsink with a good cleaner and this should be done on a regular basis ie six-monthly.
  6. Aluminum heatsink coolant is not appropriatly placed. If aluminum heatsink is not properly attached to the the processor, the processor will overheat and will likely make your computer turn itself off. The solution: Open the your CPU and carefully go to the fan and check that the aluminum heatsink attached properly on the processor.  You might also want  to check if the coolant at the alumunium surface is still clean or apply new paste if it is dirty.
