A. reverse vacuum B. any small vacuum device C. blow real hard on the system board D. use a lint-free cloth and wipe gently E. non-static compressed air

The correct answer is: E. non-static compressed air

Dust in a computer can cause a number of problems, including overheating, decreased performance, and data loss. To prevent these problems, it is important to clean your computer regularly. The best way to clean your computer is to use a can of non-static compressed air. This will help to remove dust from the components without damaging them.

Other options, such as using a vacuum cleaner or blowing on the system board, can damage your computer. A vacuum cleaner can create static electricity, which can damage the components. Blowing on the system board can also damage the components, as it can force dust into the components.

Using a lint-free cloth is a good way to clean the exterior of your computer, but it is not effective for cleaning the components. The dust on the components is often very fine and can only be removed with compressed air.

Therefore, the best way to clean your computer is to use a can of non-static compressed air. This will help to remove dust from the components without damaging them.
