Hello. I have 2 DQ77KB boards. All of them worked fine but suddanly one of them stoped to turn on.
I had try components (CPU,RAM, Power Supply) from this motherboard on second MB for exclude the probability of malfunction of them. All components work fine.
When I connect power supply and RJ-45 cable to workable MB i have seen 2 LEDs - 1 led on MB (green) and 1 LED on RJ-45 port (green), than I pressed "start" button on the Case and coller begins to rotate.
When I connect power supply and RJ-45 cable to not workable MB i have seen 1 LEDs - 1 led on MB (green) and all. When I pressed "start" button on the Case coller doesn't rotate.
The version of BIOS probably is 0056.
What is the cause of the problem and what to do?
