BleepingComputer.com: Standby/Hibernate problem

Hi All

I have my Hp Pavilion Desktop (xp home Ed) set to Standby after 5 minutes & Hibernate after 10 minutes. 9 times out of 10 it works but not always but the real problem is that when computer has hibernated it starts up again this can happen after hours & hours or after a few minutes then after 10 minutes it goes into Hibernate again. Why does it start up again?

This baffles me , can anybody give me any advice or an explanation into why this happens?

Many Thanks
