Yeah man I am looking at that graph and listening to what you are saying and that is really weird.. I don't understand how the instability would randomly overload your processor, I mean it seems like something has to tell the processor to run (operating system, drivers, programs, etc..) Maybe there is something worng with the bus drivers, Nvidia drivers have been known to freak out a little have you tried uninstalling everything and trying it again?? That is very odd another question is does Prime do the same thing?? I mean after you stop it does it overload the processor and such?? Have you considered running multiple stress tests to try and isolate the incident like OCCT, Orthos, Prime, Nvidia Stress test etc.??
