what is the setting for power restart in the bios follow you motherboard user manual to see if this is set correctly
yea boot into the bios and there is an option for something like "power on self/wake lan" or something like that. Make sure it's not checked and be sure to save settings. Tapping f4/f8 at boot should get you there in case you weren't sure..
page 64 of user manual there is a setting for power lost and on page 68 mouse and keyboard setting for wake up the system,you this do not solve the issue contact there support team for this http://www.asrock.com/support/tsd.asp
