Hello,
As in the title I've got a problem with that motherboard. At the beginning this board wouldn't POST - it would hang at CPU led, different CPU didn't solve this issue, as well as externally programming entirely new BIOS chip.
Now it's a bit worse, there is no reaction to power. However, while on stand-by, HD LED is always dimly on, as well as "GO_LED". What links these two lights is IC 6MU1, but I don't think that it's the problem.
According to the boardview PU2007 regulates VSB just fine, 3.4V on pin 2 and 5V on pin 3, but there is quite a bit of "backfeeding" into PSU on ATX plug - 0.1V on 5V and 0.6V on 3.3V. 5VSB is at 5.14V and power_on(green wire) is also at 5.14V.
I've got no idea what could cause such behaviour, so any help will be appreciated.
