Somewhat to my annoyance, since adding a new sound card I've had stability problems with SL. I tend to get booted from SL, often with the blue screen of death. I'm using an Acer graphics card (ATI Radeon HD 5400 Series) and a Sabrent sound card (Model: SBT-Sp6C), both of which are current in terms of drivers. I'd like to note that this is the only application that I've having this issue with and SL works fine if I take the sound card out.
