Disassemble the machine completely and clean the Heatsink fan, blow away the dusts from the motherboard, if possible use brush to wipe away all the dusts. Reassemble it, but don't connect or install anything on the motherboard except the the power supply, the cpu with the heatsink and the system speaker.
Now plug in the mouse, keyboard and the monitor (please connect the monitor on the integrated VGA port on the motherboard)
. Plug in the power chord
on the back and short the two terminals
of the power switch pins on the motherboard's Front Panel connectors, i.e PWR
with a screwdriver or with any metallic object you think is suitable (
Remember to switch on the mains switch (wall outlet connected to the power supply
) and make sure both the power connectors on the mother is connected, i.e. 20 pins and 4 pins.
Check the status on the monitor and listen the beep codes (the system speaker is compulsory for this diagnosis). If you see anything on the display or if you could hear the beeps, note the beep sequence (let me know if it's not 2 beeps or 3 beeps, if it's 2 or 3 beeps, the proceed forward), Switch off the machine and install one memory stick (Ram) and reboot. If it was 2 or 3 beeps, then you should no longer hear them, if you still hear the same beeps, then try with another Ram on another SIM bank(s) [Ram slot] after the machine is put Off and boot again.
If you don't hear anything or you don't see anything on the monitor, then your motherboard is bad or perhaps the integrated video card is dead or it could be the BIOS chip itself. I would suggest you to replace it, as it's not worth repair. Buying a new one will cost you less then repairing this motherboard under such circumstances.
If you see or the beeps continues, try with another working Ram, it should definitely work if the Memory module on the motherboard is still working, otherwise.. I would again recommend you to replace it.
Well, in case if it's successfully booted or the display is ok, then proceed forward by installing the component one by one and reboot everytime you install a component or plug in connector (s). You'll be able to find out the culprit, whether the hdd, or the Dvd/Cd drive or the front panel switches or others.... Will need to replace or will need to repair.
Please update so that I will be able to assist you further.
