While using your Windows PC you might have noticed sudden Windows reboot (or blue screen) without any notification. That’s what happens your PC crashes or Freezes. Sometimes your PC shows up the error messages that caused the system crash but getting to the root cause of the problem with those error messages is really very hard for a normal PC user.
Most of the system crashes are due to device driver incompatibilities, installation of new hardware and software etc. Now to know what actually went wrong, that crashed your system, you may use WhoCrashed. Its a nice free little tool that lets you know about the drivers which are causing Windows PC crash. On Windows crash WhoCrashed generates a complex log file of what went wrong.
