I just finished a new system build. Everything went great until I tried to shut down. Using the Start>Shut Down option (XPSP2) the PC will shut down but about 5 secs later it powers back on and boots. It boots fine, no errors. This is a fresh install of XPSP2, have not updated yet.
Just looking for ideas on what to try. Have read about Wake On features and disabling them, disabling hibernation.. Any thoughts would be appreciated.
