When I turn my computor on the monitor will only stay on for about a sec and then goes black. I can turn monitor off and on and it does the same thing. A new motherboard and been installed and computer works well with other monitors. Was using upgraded video card which has been removed and using orginal video card that came with computer. The monitor started acting up and before new board installed and would come on when monitor was turned off and then on. Now it just stays black after being rebooted or turned on. Can anyone help or have any ideas what could be the problem?
