I have a lenovo T440 with windows 8.1, it crashes once or twice per day with SYSTEM_SERVICE_EXCEPTION (igdkmd64.sys). I am guessing that this is the intel HD 4400 graphics drivers?
I have updated to the latest driver version 2014-05-17 (10.18.10.3621) newer than lenovos driver, but the machine still crashes.
This is using normal office applications, no gaming or any display heavy applications.
I do use 2 external monitors and the built-in screen, but it crashes with 2 screens and the built-in monitor disabled also.
DxDiag attached, I have disabled the auto updates of drivers, but I do not think this is why my machine crashes, any suggestions or fixes??
Added a eventlog showing how often it crashes.
