    No signal means the monitor is not receiving an input from the PC. This suggests the PC is failing to POST (power on self test) properly when you turn it on. This is probably unlikely but is it overclocked?

    Never mind, it obviously isn't. Does moving the mouse or pressing keys on the keyboard resolve the problem?

    i would check the cable is fitted right first, then with another if pos, then i would do the same with the vid card. if both of those still give the same results i would then guess its the screen.
