I did some searching and here's a program I found for you. Should be bette than what the other guys suggested since this does have more features.
It's called Auto Power-on and Shut-down v1.44
Here's some detail about it.
This application allows you to control your computer from the power-off state and wake it from the sleep mode. Auto Power-on and Shut-down allows you to control your computer start-up at an appointed date or time, even if the system has been closed. Wake it from the sleep mode at a specified time, and open files, play sounds, run programs, close programs, open a Web site, show a message, and make the computer stand by, hibernate, shut down, or reboot at any specified time.
Anyways, here is the donwload link.
