Power Mac dual 2.5 sleep problem

I recieved my dual 2.5 last week. Just yesterday a problem occurred after sleeping. I can put it to sleep fine by pressing the button, and it will wake up fine with either the mouse or the keyboard. But as soon as it is awake, none of my inputs plugged into my computer work. The keyboard, mouse, and ipod. Nothing will get a response on screen. Also after putting it to sleep it will not go back to sleep by pressing the button and I have no way of doing it through the OS. The only thing I can do is hold down the power button until it turns off. Since this has happened I have run the extended hardware test with everything passing, repaired permissions, and restarted multiple times. I am kind of out if ideas and was wondering if anyone has any suggestions or this has happened to anyone.
