Dust Kills the Computer
This computer was only 2 1/2 years old, and it failed prematurely. That could have been avoided had it been maintained at least annually and had the dust cleaned out. The heat sink cools the processor (the brains of the computer), and it requires a good, clean airflow.
If you have pets or are in a dusty environment, then the machine should be cleaned every 6 months.
How can I avoid this? A sure clue your computer is dusty is the noise the computer fan makes. If you notice it getting louder, then it cannot push the cool air
through the heatsink.
Your antivirus protection can also be checked at the same time.
