I went to turn on the computer, got a small static shock, and the computer won't turn on now - totally dead, no response when pressing power button. Does anyone know the hook up of the power on/off switch in ATX12 ver 2 PCs ? I notice that none of the LEDs are lit now - so "stand-by" power must be dead. Details : Case : Antec Sonata 2 MB Gigabyte GA-M59SLI-S5 9 (AMD socket AM2) Does the signal (Momentary Short to Ground??) of the Power button go just to the MB, just to power supply, or both? Thanks for any help you can give me Mike K
