Vista on boot camp does not goto sleep

I just installed vista home premium on my core 2 imac with bootcamp. I have few issues

1. Performance Counter driver? What is this and where do I get this

2. Vista does not go to sleep, does not go in to screensaver mode. I have tested this many times. Pushing the sleep button does put the mac to sleep (including blinking light on the bottom right of the computer). But it will not go to sleep according to the power settings. It will also not go to screensaver. I think I am missing some kind of power control driver. Any ideas?????
