Hello Fory,

In addition, check using the tutorial below to see what last woke your computer up to see if it can narrow it down to a specific cause, and post back with that information. We'll see what we can do to help.

Ensure you haven't left a disk in the CD/DVD drive. That will cause some optical drives to run at full speed after awhile.
