Tried disabling the Legacy USB but since I'm using basic USB mouse and keyboard, they don't work when doing that. I also disabled the USB3 so its supposed to run USB2 only. That didn't work either. Using a stick in the USB port still shuts downs the system.
I also tried using just single memory sticks (tried both sticks) USB still crashes system.
BTW, my RAM is 1.67v Muskin DDR3 dual channel. Since the motherboard automatically sets the RAM voltage at 1.58v, I bumped it up to 1.64v. System booted fine and RAM tests were good, but USB problem did not go away.
Anything else?
