Server 2012 R2 unexpected crash DRIVER_IRQL_NOT_LESS_OR_EQUAL

Solution 1:

When everything is working great and then suddenly you obtain driver exceptions it is either 1) a driver update caused a problem, which is unlikely, or 2) you might consider that the hardware is failing. If a component is dying then drivers will start throwing exceptions. Do you have another server you can move the drives into? Alternatively, start switching out components, if possible.
