I'm having a very similar problem, began ~ 2-3 weeks ago. Sorry Tom I'm not sure if it was right after an update.. Here's what mine does: A) After a random span of time, could be 2 minutes or 2 hours, my crt monitor trips to standby mode. (I have set windows power options to always on, never shut off monitor/disks/etc) B ) All sound is off, almost as if the power on the pc has been shut down. PC drives and fans are still spinning but no access, cannot ctrl-alt-del, alt-tab, alt-f4, ctrl-x (matrix spoof lol), or anything. C) Need to restart pc to bring it back to life, and unfortunately no logs are up todate becuase it was hard-booted. I've also disabled windows screensaver, however not the attract screensaver because im constantly manuvering around gameex. I've replaced video card, ram, and even reinstalled windows (yes, lol) . This doesn't just happen to me while playing games in gameex, also around the gameex menu's it will do this to me. -Matt
