Describe "turns on", do the fans all spin up and you hear the hard drive start up too?

If so, and this is not a new build, im thinking that you have "Power on on AC loss" enabled in BIOS, which means when the PSU looses power then gets it back the motherboard will automatically boot the system. As for why it doesnt get all the way, you are probably failing post somewhere along the way, go through this check list to figure out where

you should try to disconnect from power; unplug all USB and then connect PC back to power and you will see...i got the same problem and cause was that the mouse was plugged into 3rd usb port and that starts my PC automatically ....
