I’m using Asus P5B deluxe/wifi-ap, 965 chipset. I have intel speedstep enabled, q-fan control enabled. I made a new power management profile, oriented on low performance and low power requirements. I use this profile only during the night to lower the pc consumption since its on all the time. When I have balanaced or high performance profile everything is ok. when I switch to low performance, it takes only a small amount of time and windows explorer freezes and restarts. I also noticed that when I wake up the pc from screensaver, the whole pc “freeezes” – the pc acts like windows explorer is not responding, and nothing can be done, have to reset the pc. This happened to me like 2times. Anybody experiencing something like this??
