You should check several things for several reasons.
1) Update your Windows. Many energy savings issues have occured with windows for the type of power profiles set incorrectly in the bios. Use defaults and check if it sleeps normally, and returns to an active state normally. Many MS KB articles have addressed most of the power state issues of the major brand board systems.
2) Replace the bios battery. This keep the profile settings active after shutdown.
3) Check your Mainboard pin connections for your headers. Make sure they are "polarity correct" and also in the "correct placement" for the case switches.
(this is what i'm thinking is the issue, as i've seen the same problem with user built systems too many times to count)
