That's the problem: NO errors in any of the logs, no mini dump from Sonar, and if I try to force one through the Task Manager, I can't...it's locked up, too. :(
Not a problem, that's telling us it's drivers all over...
Just update your drivers and firmware everywhere. Display, audio interface, etc. You could even try updating your motherboard chipset and BIOS.
One of these will probably fix it.
