[Blind-sysadmins] win7 power and not waking up with wireless keyboard or mouse

Hello, I've got a new win7 64 bit machine. It's not working power wise, when it goes to sleep, it does not shut down it's fans, nor can I get wireless devices, I've got a wireless keyboard/mouse attached to it, and neither will wake it up. Currently, i've got a usb wired mouse hooked up and it takes that to get it to come back. I was thinking it has something to do with the system's power plan, and not sure why though it won't shut down fans, nor why wired keyboards and mice can get it to wake up, but wireless same can not. I'd appreciate any suggestions. Thanks. Dave.
