    Where can i get the last version of "iastor.sys" driver?


      Hello everyone,

      Since the last days of March, my laptop started to get bluescreen very frequently, both during an intense use or at rest.


      The error is always the same:  DRIVER_IRQL_NOT_LESS_OR_EQUAL


      I downloaded the software WhoCrashed to understand better what was the problem, this is the report:
