This is driving me nuts, as i don't see many others with same issue. All steam games crash within 3-6 minutes. Locks up so bad, it takes a power down/reboot. 7 sits on its own partition, fresh install, newest ATI drivers for 7 were installed, yet to no avail. Not seeing it here yet, but ive read...
