This is not operating system specific, it did this before I even installed anything. So I have an Intel D945GCLF motherboard and hooked up an extra power supply to it. The only thing I have hooked to the board is the 20 pin ATX connector and the 4 pin P4 connector, that's it. No power button, nothing. As soon as I plug the PSU into the wall, the computer boots up. I've never seen this before, any ideas? The CMOS battery was dead so I replaced it and it's still happening.

Plus whenever I turn it off, it turns on by itself a minute or so later.

Do you have any PCI devices installed? You might need to change a setting in your BIOS. On my computer, it's called "PME Event Wakeup," under "power management." There are several other "wake up" settings in my BIOS.

On another computer it had a different name, which I do not remember. I installed a PCI sound card and the computer immediately powered up, so I had to change the setting.

Turn auto power on after power off in your bios off. it's intended for if theres a storm or something and your electricity gets cut while it's on it turns itself back on once the power is restored.

No PCI cards and that auto on setting is already off.

Are the pins for the power touching each other through metal or directly somehow?
