My notebook is suddenly making lots of noise! What should I do?

Update Time:2016/10/20
he amount of noise your notebook makes depends on many factors - obviously, on the operating temperature and the CPU load, but also on the operating system configuration, installed drivers, and the BIOS. Did you reinstall your OS before the problem occured? Installed new drivers? Upgraded the BIOS?

In some cases, it may help to put your notebook back to its original operating system configuration with the aid of a recovery CD (or recovery partition) supplied by the manufacturer.Refer to you notebook's documentation for instructions how to do that.

If you believe that the noise is related to a defect in the notebook's cooling system, read below.
