I was using gpuz since 0.27 on same system and everything was fine untill a week or so ago. It just started refusing to start. That was with version 0.30. I got the 0.31 but same error message: "Could not start driver: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it." I have 4850 512mb, c2q 6600 @3ghz, 4gb ddr2, asus p5q running vista 64. I have ati 8.12 catalist drivers. As far as I can tell, I didnt do anything, but GPUZ just started rejecting to work one day on random. I like to start GPUZ every once in a while to check GPU temp, and one day gpuz just failed to load with that message. It has been like that ever since. I reseted and turned off/on computer many times. Everyting else works flawlessly, no bugs, BSODs, slowdowns... nothing but smooth everything except GPUZ wont work. Any help appreciated. Thank you!
