My MacBook won't sleep without immediately waking up, and won't shut down without immediately restarting. I can turn it off by holding down the power button, but it still turns back on when the magsafe is plugged in.

It seems like I need to reset the SMC, but when I follow the instructions to do that (turn off computer, push left shift-control-option-power) it just turns on. Is there another way to reset the SMC, or is there something that I'm missing?

Os X Reset Pram

I have a MAC PRO 3,1 8-Core that all USB ports stopped working, I tried the SMC reset, and it does not work, PRAM and NVRAM reset dont work since the USB ports don't work, I dont have a wireless keyboard or mouse (bluetooth), and even if I had I cant configure them since I cannot use the mouse or Keyboard. so basically stuck. Im really frustrated, could this be a logic board issue?
