Got an Aopen AK77-600GN and it was working fine at last switch on. Now I'm not getting any BIOS beeps or boot up. I am getting power to the board as the standby LED is on and the cpu fan is running. I've taken the board out of the case and tried it with just the cpu/heatsink/fan, no joy. Tried it with a single stick of RAM in all the slots, no joy. Power Supply in the case is good as I've checked it with a multimeter, as is power out of the power connector. At a bit of a lose now. Can anyone give me any more pointers to try? TIA Claude
