I have built a Gigabyte GA X79 UD3 with Intel i7 4820k and I used my previous PC Power and Cooling S750 power supply. When the system sleeps, it powers down instead. Could that be that the power supply is not ErP compliant? Thank you.
I am sorry for not being specific. I mean it doesn't sleep, it powers off. Therefore it doesn't wake up. I have to start it from the power switch.
So I have called Gigabyte and they said try updating video drivers, and if that doesn't work buy an ErP compliant power supply. Video drivers didn't help, so I ordered a Corsair TX850M.
