The way that the system bios functions is to detect that the Microprocessor is too hot. The operating system now shuts the computer off. This is done to protect the microprocessor and other components from damage. Some of the effects from this are losing data. For example if writing a document or saving data. If the computer shuts down suddenly there could be damage to your hard drive.
It would be a good practice at least once a week check inside the computer and check for dust building up. If it looks clean then check the computer every two weeks. The environment the computer is located in cause the computer to become very dusty. Being close to the floor may cause dust to build up. If the computer is near an open window it may collect dust. Pet hair can collect in a computer.
Do not use a vacuum cleaner to suck the dust out. The vacuum cleaner tip and hose are not static safe. They can damage many of the components with what is call ESD or electo static discharge. Don't use a paint brush to clean off the dust from a component. Don't do this, because the paint brush is not statically safe.
Use Canned Air Duster to remove the dust from components in the computer case . I would suggest to purchase the canned air duster from Amazon, Ebay or at a local store such as Office Max. Before using the canned air unplug the computer from the surge protector so there isn't any electrical connection . Hold the fan with your finger when blowing dust from it. You could damage the fan by it moving too fast. Moisture can form on the components from the compressed air. The moisture could short components resulting in damage to the motherboard etc.....
|Example Of Blowing Out Dust with Canned Air|
Any dirt and dust built up on the fan blades can be cleaned with glass cleaner or household cleaner on a q-tip.
Cleaning the dust out of a laptop computer can be a little more difficult. You may have to dissemble it to remove chunks of built up dust.
Thank You for reading and have a nice day.
