Hi guys,

It all started when i was changing the Network Card. After, i installed the new one, the pc when turned on, starts to beep. 2 beeps then immediatly 6 beeps.

I tried the VGA, the RAM, the hard disk on another pc and they all worked.

Now I disconnected totally the motherboard from the case and only connecting the VGA, the Ram and the hard disk. No beeping is sounding but also nothing is happening.

What should I try? what should I test?

I disconnected all the pins of "power on", "sleep led", "reset SW" etc.... and there's also a pin with 4 openings and 2 wires on the sides (1 black and 1 red) which when i connect, the beeping start again.
