Not exactly on topic, but related to this issue for those on Linux using proprietary nvidia drivers. Apparently, the latest version of the driver, 295.40, suffers from some serious bug that tends to slow down the system and occasionally max out X to 100% system resources, with consequent freeze. The issue as surfaced among Archlinux users and has also been reported elsewhere. Some users have benefited from downgrading to the previous version. Others, like me :-(, are still waiting for a revised version to come from Nvidia.
