Still no change with the latest versions? Btw when reinstalling OT, move the existing data dir away or install to a new data dir, to ensure there are no corrupted data files.
Freezing that way must be a driver/OS thing, it's not really possible for an application to freeze the OS completely in user mode. Since you did all the cleaning with the graphics drivers, and presumably this is not a hardware issue ... the only other drivers used by Outerra are network and sound. But that would be quite unlikely and rare (though, your freezing in OT is indeed rare).
