your PSU voltage is ok, but 5.8V on 7805 output can't be normal... (max 5.2V)
Have you pulled out chips from motherboard to read 5.8V? in this case the "current helping" of R10 can be too much and overfeed the 5Vcc.
Another component to check is diode D11, it is near heatsink and the ceramic resistor, after some seconds of power up put a finger on it: if it heat the diode is damaged (leakage reverse current).
