AkemB.
I have a habit of unplugging my sound interface (Focus rite Scarlett Solo (2nd Gen) USB Audio Interface) as a way to save a tiny amount of power; the interface emits a small green dot. This time, I did the deed with a guitar amp simulator open (Cakewalk by Band Lab). At first, I blamed the software and moved on to Amplitude 5. Yet again, another blue screen. I was trouble shooting this for a solid 4 hours to no avail. One thing was common, the blue screen only happened if there was an amp simulator running, and the sound interface had been physically disconnected from the tower. Additionally, there were no bluescreens while disconnecting with Audacity running. This is what the bluescreen itself had said during reboot “stop code: SYSTEM_SERVICE_EXCEPTION, what failed: FocusriteusbSwRoot.sys”. Drivers for the interface are up to date. Any assistance will be greatly appreciated.
