Computer Keeps Shutting Down: Computer Overheating

User Rating:  / 5

Computer Fans Keep Your Computer Cool

Whether you use a laptop or a desktop computer, your computer has fans inside to keep cool air flowing through the computer case, keeping the components and parts inside cool and running at the correct operating temperature.  These fans by default will operate in a similar manner to your home A/C unit.  When the temperature on the inside of your computer is high, these fans will turn on in order to cool the components down.  The fans will continue to turn on and off in order to keep the inner parts of your computer at a consistant temperature.

Computer Fans Always Running on High

If your computer keeps shutting down randomly, you may notice that the case fans inside your computer are running more often, and may sound like they are running much louder or faster than normal.  This is a good sign that something in your computer case is running too hot and is overheating, or that the cooling fans are unable to cool down the computer at normal speeds and must run higher in order to stop the computer from overheating.  This may be a sign that it's time to clean your computer case and attempt to increase the air flow through the computer and cooling fans.

How to Fix an Overheating Computer

If your computer is overheating or keeps shutting down randomly, you may need to open up the computer case and remove dust from the components, vents and fans.  When dust builds up on the inside of your computer case, it restricts airflow through the computer and the components inside may begin to overheat.  Without regular cleaning, dust will build up inside the computer and can cause immense damage inside your computer and to your components should it overheat.

Use a Vacuum to Clean Computer Vents and Fans

Many people will discourage using a vacuum to clean a computer, but when done properly it can help increase airflow through the computer and prevent it from overheating.  While it is not recommended to open your computer and use a vacuum to clean the parts and components, using the vacuum hose will allow you to clean dust off of computer vents and fans without forcing the dust inside of your computer case.  This is especially helpful with laptop computers because they can be difficult for a novice when attempting computer repairs.  If you are using a desktop, it may be a good idea to remove the motherboard, power supply and any removable disc drives or hard drives and vacuum out the inside of the case.

Use Compressed Air to Clean Computer Components

If you are comfortable with opening the case of your laptop to clean inside, or if you have a desktop computer, the best way to remove the most dust from the inside of your computer is to use compressed air.  These can be found at any hardware store or local shopping center and generally won't cost you more than $5 or $10.  With the straw attached to the canister, hold the tip of the straw 2 inches away from the computer component you wish to clean and blow air at the part in short half second bursts.  Make sure not to use long bursts as the canned air may freeze quickly and start spraying liquids onto the computer parts.  Make sure that your remove as much dust as possible and remember to blow air through the heatsinks and fans to remove as much dust as possible from critical components and to prevent computer overheating.

Cleaning Your Computer Regularly Prevents Overheating

If you regularly clean your computer vents and fans, and internal components, you will greatly reduce the risk of computer components overheating, which will help prevent problems and keep your computer from randomly shutting down.

If you are still experiencing issues after cleaning the components of the computer and it continues to keep shutting down, you may need to take it to a computer repair shop to ensure there are no damaged components and that everything is working properly.
