Check the BIOS. Most have an option to power on the computer at a designated time. You can disable this function.

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.

If it is just waking up from sleep then it could be that Windows is installing updates in the middle of the night.
