Additional information

Event Viewer ID 37 is part of the normal frequency/power management that exists on all platforms. 
For example, the OS requests more power/frequency due to increased Hyper-Threading/Applications running. The firmware responds and denies it due to the maximum power for the current system has already been reached. This basically means that the processor is being managed by technologies such as Enhanced Intel SpeedStep® Technology, Intel® Speed Shift Technology, etc.

If the previous steps do not fix these warnings, it is recommended to perform a clean installation of the operating system in case of software corruption.
