|"No signal input check video cable"|
The monitor's not getting a signal from the video card. The problem is not with the monitor.
"I even moved the CPU to another moniotor but it still did not dispaly anything"
A CPU is a chip that fit's in the motherboard, it's also known as a processor. You apparently have a dual core CPU. I think what you mean is you tried connecting a different monitor to your computer but that it still didn't work?
Are you getting any kind of beeps when you 1st bootup?
