the motherboard is powering on but no display also i checked that 3.3v from PSU is showing 2.8v and there is one IC GR8313 for PG signal generation that ic pin 8 is PG out and no voltage at that pin , also i checked with PCI post card and it is showing 0000 code and Reset LED is steady and no clock and reset signal present. please help.
You can externally supply low voltage with high current, the component that sinks all the current will get hot, so touch them individually to find which one is really hot and that is the one most likely faulty. Unplug the computers ac power source before you do this and take every precautions while you do this.
