Hi guys,
sorry but your answers are not completely right, I´m no superman but experienced things over the years.
Software CAN cause Blue Screens, when it has incompabilities with hardware.
We had it here with Samplitude, which caused BSOD´s like crazy, while Cubase was running fine on that very same machine!
Reason for that was, that Samplitude had a problem with UAD2, and could not properly talk to that card.
Sonar is a bit picky with plug ins and hardware as well, so you´ll have to check things out.
For example, unplug your Octacapture and run Sonar with ASIO 4all on the native I/O of the laptop.
If it runs fine, there´s a problem with the interface.
Most of the times, when BSOD´s are related to hardware, it´s a memory failure, so run memtest and check your memory..
For me since X1 expanded, things are very stable here, can´t remember my last crash..
Good luck
