I hope someone can help me with this dilemma! I have an e-machines 8220 2.8 GHz pentium 4. Sometimes when I turn on the PC by the power button the drive light remains constant without booting up and can only turn it off by holding the power button for a few seconds. This can happen between 8 to 10 times and then will turn on. Also the PC turns itself on and I have disabled wake on LAN. Once the PC is on it works fine, although I have uninstalled absolutely every program we don't need in case any one was causing problems. Do you think it might be the power supply.
