Depending on your environment, you need to dust your computer every six to twelve weeks. Some of the things that contribute to having more dust are pets and construction near by. Use canned air to dust your computer. Canned air is easy to use and is available at most computer and office supply stores.
To dust inside your computer, unplug your device and turn it off completely. After you open the case of your desktop's tower, use a can of compressed air to spray inside until all of the dust is gone. Avoid using a vacuum cleaner, as they create static electricity that can damage your device.
If you don't want to hurt your PC's performance and lifespan with the added stress and heat, give it a good cleaning at least every six month to a year. While the average user's computer lasts several years, true cleaning of hardware and software could extend your PC's useful life by a few more years.
External cleaning frequency
To keep your computer sanitary and free of germs, follow a proper maintenance and cleaning schedule of every three to six months. If you notice lots of dust following cleanup, you may want to increase the frequency to reduce the dust and debris buildup.
The build-up of dust from a year can cause overheating because it clogs up the filters and fans. The negative effects of your computer overheating include your computer crashing, a shorter life span for your PC, and potential data loss. The best way to avoid this happening is to keep your PC clean and well ventilated.
It's inevitable that dust will end up in your system—whether you use it all the time or play once a week, gaming computers love dust. We suggest you clean your computer every three to six months to keep your system looking its best and to prevent a significant reduction in your PC's lifespan.
Although you aren't really “boosting” the speed of your PC beyond its normal state of operation, you are reversing the slowdown that has occurred over time due to the dust that was building up (essentially, boosting it back into normal operation).
Just turn off the laptop, unplug the power cable and remove the battery (if it's easily removable). Grab your compressed air, give it a quick burst away from the laptop to get rid of any condensation, then start blowing air into any cracks and crevices: the keyboard, the vents and even the USB ports.
Power down the laptop, remove the battery, and unscrew the panel to get at the laptop's insides. If a service manual is available for your laptop, it will walk you through the process. You can use the compressed air, but if you don't have any, don't buy a can. Just use a brush, and blow out the rest of the dust.
Dust can block filters and prevent air from flowing through the computer and causing it to overheat. Dust also acts as an insulator which can add to the heat build up. Dust can also cause a short in circuit boards and integrated circuits causing computers to crash and in some cases- even catch fire!
Open your PC and have a look, if dust have covered most of the fans and the heat sink you really should clean the PC. I clean mine once every two weeks, minimum.
Unclean computers and servers can harbor Bacteria, mold, and dust which can be the cause for everything from allergies to asthma. If your computer is not cleaned regularly, it can spread these germs and make you and others sick.
Accumulated dust in your CPU can prevent your processors from effectively cooling and prevent excessive heat from staying trapped inside your PC. This, in turn, can affect the speed at which your computer performs.
Use canned air to dust your computer. Canned air is easy to use and is available at most computer and office supply stores. Don't use a vacuum cleaner. A vacuum can create static electricity that can damage computer components.
Dust is inevitable in any environment, but it can cause serious problems for your computer if you don't clean it regularly. Dust can clog your fans, vents, and heatsinks, reducing the airflow and cooling capacity of your system. This can lead to overheating, performance issues, and even hardware damage.
Also allow your computer enough time to completely air dry before reconnecting power and turning it on. It shouldn't take long if your cloth was only slightly damp, maybe 5 minutes or so. If you can wait longer, do so.
The extra time that you take to clean up the inside and outside of your gaming PC will ensure that it's running at maximum capacity and thus will improve your gaming experience. We recommend cleaning your computer every three to six months to keep the performance up and increase your machine's overall lifespan.
Hardware issues that lead to the computer keep freezing
A more severe problem is a hardware issue, where a particular computer component is not working correctly or is malfunctioning. This can happen for some reasons, such as overheating or excessive dust buildup on components inside the computer.
All computer fans are not created equal; there are case fans to keep the computer case cool, CPU fans to blow hotter air off the processer, a power supply fan, and a video card fan to keep powerful video game cards from overheating. Any or all of these may require cleaning.
When dust coats the fan blades, it takes more effort for it to spin, causing it to run louder and perform less efficiently.
Normally, dusting out the inside of your company's computers on a monthly basis (more if the environment is unusually dusty) is sufficient to keep RAM modules clean, but if the need arises you can also clean the contacts with rubbing alcohol.
Every time their internal fans turn, drawing in air to keep its inner workings cool, they also draw in thousands of dust particles as well.
