Core-15 2500k, 16GB ram, Win7 Ultimate.

My machine has lost two features. Suddenly, and for no apparent reason, my autorun has stopped working. If I insert my memory card the little window doesn't pop up and ask what I want to do. In the past, the menu would pop up and ask if I want to run, or view in folder, etc. Would like to get that back.

Also, the power management choices have not changed, but my computer will no longer sleep. screen saver comes on, sometimes the display will shut off properly, but it never goes to sleep as it should. It is set to sleep at 25 minutes. Anyone help?
