S!
No my GPU is not part of the Hadron Collider Experiment
Yeah it does effect only steam games, i have no problem what so ever with non steam games.
My PSU is about 1 year old and i have no other related problems i guess that would present themselves if it were a PSU issue.
I will disconnect my card, reboot my pc without the card and fully uninstall all ATI drivers, reboot. Shutdown. Reinstall Card and drivers and pray.
I really cant afford a new card right now
