How often should I dust my PC to maintain its optimal performance and longevity? Is there a specific frequency that is universally recommended, or does it vary depending on individual circumstances? For instance, does the environment in which my computer operates play a significant role in determining how frequently I should engage in this maintenance task? If I reside in an area with high levels of dust, pollutants, or pet dander, would that necessitate more frequent dusting? Moreover, are there particular signs I should look for that indicate my PC is in desperate need of a cleaning session? Is there a risk that neglecting this duty may lead to overheating or hardware malfunctions? Could the accumulation of dust not only affect aesthetic appeal but also contribute to performance degradation over time? What best practices should I adopt to ensure I am dusting effectively without causing harm to the delicate components within my computer?
