Computer beeps then shuts down


Problem: Your Windows computer beeps then shuts down, this mainly happens to laptops/notebooks because of their miniature design. Why does it happen? It’s due to overheating and your computer has self-preserving protocol to prevent it from fire. My 4-year old Sager laptop was no exception.

Disclaimer: You’re at your own risk, if you damage your computer or injure yourself in the process, you cannot hold me responsible or liable for it.


  1. Unplug the power cable going into the laptop.
  2. Flip the laptop upside down and unscrew the screws holding the bottom cover.
  3. Unscrew the metal plate cover that is sitting on top of your video graphics fan, as well as heat-sink fan. Unscrew the screws holding the fans to the casing.
  4. Unplug the little plugs that power these fans and remove the fans.
  5. At this point you will see carpet-like dust build-up on the heat-sink grills (See image below).
  6. Using a vacuum machine with small brush nozzle, vacuum out all the dust from the heat-sinks as well as the fans (both sides of the fan and its propellers).
  7. Reconnect the fans and screw back all the screws you unscrewed, don’t forget the bottom cover while you’re at it.
  8. Send me a post-card if the above helped.
