A system for preventing processor errors in accordance with one exemplary embodiment of the present disclosure has a processor core, a patch, and a controller. The patch configures the processor core to detect occurrences of an event indicative of an imminent error in the processor core. The controller is configured to adjust, in response to a detection of an occurrence of the event by the processor core, a clock signal or a power signal provided to the processor core such that the imminent error is prevented.
