Recently switched out an old motherboard for a GA-970-UD3P. Everything works great, except I noticed that when I use the reset button on any case (tested with 3 cases) that the system freezes; the screen goes black, keyboard and mouse are unresponsive but the computer is still powered - fans are running, leds are glowing. Have to switch off and on the PSU to get it running again.
Anyone have any idea what could be causing this? This did not start happening until I switched out to a new motherboard, everything else in my system the same from when I Had the previous motherboard (where the reset button worked just fine).
