Windows 7 pro USB 3.0 , something did make the laptop freeze for a 10 seconds or so to, dont know much about technical stuff tbh. I was thinking the warning (be sure ur device is idle before push start) was the problem. Wat does idle mean on the opus, complete black screen or just dimmed, as mine was just dimmed when i pushed start? *edit* Damn this board is quiet something else, very impressed after using it awhile. Cant wait till my ti wire is here to play with that. Great job evolv, opus is very nice to, been lurking at those since the opus 20, was the perfect moment to get of those, so happy i made the jump.
