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.

You must have been in a situation where you’re pissed off  because of a slow computer shutdown while you’re in a hurry.  If you take a shortcut by shutting down by force before  the shutdown process is complete you put yourself at risk of damaging your computer or notebook. Then how to accelerate computer shutdown?

You can speed up computer shutdown by modifying Windows registry key. After going through the following registry modification procedure you will notice an increase in shutdown process. As usual before you proceed you’re advised to make a full back-up of your computer registry just in case you’re not following the procedure correctly. Note that this tips  is only  applicable for computer running Windows XP/Vista/7, other window versions may have different registry key locations.

In this case I do the registry modification in Windows Vista to make the computer shutdown faster. When your computer is being shutdown, your machine needs time that must be passed until the process is complete to ensure and all Windows system is closed. By default, Windows set  twenty seconds as the time needed to perform this which is simply  too long. You can cut down this shutdown process with  a simple registry settings tweaking.

Folow the step-by-step guide carefully otherwise you will end up getting a painful consequence  because if you perform the following procedure the wrong way, your computer won’t boot up

1. Click [Start] and then on the box [Start Search] typing [regedit].
2. In the windows registry locate the  following key: [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl]
3. Once you find it, while on the right pane, right-click on [WaitToKillServiceTimeout] and select [Modify] , see picture bellow:

Under  EditString window , change the default  number of 20.000 with a figure  between 5000-10000. Do not put with figures  under 5000, because by doing so  you do a  force shutdown. If you set the figure to  6000 it means you set your computer to shutdown in six  seconds After you specify the numbers click [OK] and exit the registry then shutdown the  computer twice. Your computer will now shutdown within the time you have set above.

Now you have fix a slow computer shutdown
