what is the problem with this motherboard...?
the circuit is traced and it was found that just it before it goes to a
southbridge there is a resistor. the oncircuit measurement of the resistor is 9.7k. But the voltage is 3.3 V on one side and the side of the resistor has zero voltage. SO what is wrong here? |
