thank you guys for your concern... it was the cmos setting... i didnt understand what was wrong but my engineer did so its all cool now....! what the hell is cmos setting ? what could be wrong with it ? he did nothing but just pressed it or something and the pc started working..
If you would have followed the link I gave you above, you would have found this:21. Have you tried resetting the CMOS? The motherboard manual will have instructions for your particular board.
and probably solved your problem a couple of days ago.
Glad your back in business anyway.
