nothing happens, when i click on the power button...
and again if i remove the card, the system starts.......
tried with other normal lan cards,,,,,(10/100) and the system starts normally...
but with these cards,,,(10/100/1000,(SVB International) the system doesnt start at all....
but all the cards working well...on the rest of the 6 pcs.....
