It possible for the Saffire 6 usb to bluescreen a Windows 7 or 8 pc when it is either connected or disconnect with the computer on. This is normally caused by the usb chipset drivers on the computer being out of date. To resolve this please go to the computer or motherboard manufacturers website and download the latest chipset drivers. You should also be able to get the chipset drivers directly from the chipset manufacturers website. If you are unsure of the usb chipset your computer has, please contact the computer or motherboard manufacturer.
