PCs can last anywhere from a few years to several decades, but they will eventually need to be cleaned. Here are some guidelines for how often you should clean your PC: -Every 6 months: If you use your PC for basic tasks such as email, browsing the internet, and writing documents, you don’t need to clean it as often. However, if you use your PC for more intensive tasks such as gaming or video editing, it’s recommended that you clean it every month. -Every 3 months: If you use your PC for basic tasks such as email, browsing the internet, and writing documents, but rarely play games or edit videos, you don’t need to clean it as often. However, if you use your PC for more intensive tasks such as gaming or video editing on a regular basis, it’s recommended that you clean it every 3 months. -Every 6 months if using the computer for gaming or video editing: If you use your computer regularly for gaming or video editing (more than 2 hours per week), it is recommended that you clean it every 6 months. ..
