sorry for my bad english...
Got the same errors multiple times. AsRock Pro3-m / I5 2500k
Managed to solve the Problem:
There are 3 Pins (+5V, - ,GND) for the Reset SW connector on my Board. My case had a 2 Pin (+5V,GND) connector. So it doesn't fit... It could be that you made the same mistake
I unplug this connectors and the errors didn't return till now (3 Days).
