Hi there, I've been looking for some help regarding this issue. It has become more frequent over the last 2 months. Each time, the message is the same: driver_irql_not_less_or_equal I have attached the most recent save.dmp file. Could someone advise as to what the issue might be? I built this pc 2 years back and haven't had many issues with it until this. I have recently updated my sound and video drivers in an effort to tackle the issue but with no success. I am using on-board sound.
