I've been getting weird issues ever since I started running 2 SMP clients on my Quad. My screen will go black after running the GPU client and it's like 5-9% on a WU and Vista will say the device driver stopped responding and recovered, ect. Then when I restart the GPU client it gives the Early WU end error. However, both SMP clients are running fine. I also tried reinstalling video drivers. I don't get any device driver failures while playing games. All three client are on different Machine ID's. Does the GPU client need the '-local' tag now too or is it something else?
