when I want to turn on my computer I can't just press the power button, I have to either unplug the power supply from the wall and count to like 30, or switch the hard power supply switch to off and count to 30, and the switch it back on again. After that I can power on my system by just pressing the power button. Additionally, if I just turned the system off, I CAN just press the power switch to start it up. But if I keep it off for more than 15 or 20 minutes, I have to switch off or unplug it. Hmmm?
