Hallo
My Windows 7 machine returns from hibernate state by it self, almost every morning the computer is on.
What could possible be wrong? I didn't have any problem when I was having Windows XP, so it can't be the hardware.

Check your time service notifying settings:

If that doesn't help, just open the event viewer, click on the System log in the Windows Logs folder, and filter on Kernel-Power events. You will see the machine go to sleep, and afterwards there will be another event showing the machine waking with the device, driver, or reason (if known) that triggered the wake event. Note that if a scheduled task wakes a machine, it should also go back to sleep after the timer has passed again after waking, so if the machine stays on it's usually a rogue program or a misbehaving driver.

you can use powercfg to see what wakes up the PC:

powercfg  -WAKETIMERS

and

powercfg -devicequery wake_armed
