I have a strange problem. Whenever I start my computer, it starts to boot but the monitor is not displaying anything, the power light on the monitor is off too. It is like monitor is off. The computer boots up properly and no problem on OS. But if I press the power button on the monitor then press it again the the picture comes and everything is ok. The computer and monitor all are working fine thereafter. The problem is just at the time of start up. plz help me.
