The type of error you are receiving (DRIVER_POWER_STATE_FAILURE) is often caused by third party firewall drivers.
There appears to be Sunbelt drivers, such as the SbFw.sys, loaded on your system that may be at issue.
Try removing the Sunbelt drivers and see if the issue resolves.
The Sunbelt drivers may be a component of Ad-Aware and seemed to be the issue in the following thread:

There appears to be two Sunbelt drivers still loaded on the system, the SBFWIM.sys and the SbFw.sys.
These drivers should be able to be removed manually along with the corresponding registry entries.
However can you run the spfclean.exe (Sunbelt Kerio utility) in the following link:

I would recommend to create a System Restore point prior to running this type of application.
Afterward check that the SBFWIM.sys and the SbFw.sys no longer exist in the C:\Windows\system32\drivers folder.
