[SOLVED] Urgent question: Starting up on its own

My new Hackintosh is starting up on its own after I shut it down - usually after about 30 seconds. How can I stop it doing this??

Disabling Wake on LAN in BIOS did not fix it.

Try something simple like taking your ram out of your system, make sure you unplug your computer or turn off the switch and wait a while before removing. Also try one stick or 2 sticks of ram at a time. Also if you have windows unplug the osx partition and try to see if it's related to the disk some how. That way you know its a hardware or bios issue.

Hey there, thanks for your reply. I think I've found the culprit, and it's not ideal. The computer is plugged into the monitor via USB 3.0 in order to power the monitor's USB hub. Useful for mouse/keyboard etc. I think the screen was pulsing power back and turning the computer on. Seems to be solved when I remove that USB connection but I'll keep testing!

Glad to see you found the culprit...ya best way to troubleshoot is to eliminate variables as much as possible. I had restart issues back in the z68 days.

Good luck
