I know this has been covered many times but i thought i would share with you another solution.
Blue screen on Initialisation of Gigastudio. (either when stand alone or when cubase activates it)
i had just replaced my mother board. it had a sound chip on-board that wanted to load a little file called: RTHDCPL.exe (this seems to be the one that causes the issue)
Simply follow the instructions below to stop it from loading at startup and no more bsod
start - run (type in msconfig)
Go tothe "Startup" tab
take the tick out of RTHDCPL.exe
