@Gabi Its a known issue with the gigabyte boards. It is known as coldboot issue I believe. The reset procedure is to take the cmos battery out, leave the pc unplugged and batteryless for about 10 minutes and then it will work again. I had the same first reaction as you when I had the issue first time. Not fun. Typically it happens when the machine is left powered down for a while.
