i was doing the tutorials on a virtual skipper online sailing game, i had completed 5 tutorials, clicked on the 6th and got the BSoD. I had 3 or 4 internet sites open so I thought that I have overloaded virtual memory or something. System rebooted and ran fine, the following night I tried again without anything else running and as soon as i clicked the 6th tutorial, got the BSoD, the error report stated cmuda.sys, Any clues?
