I am a user of Windows 7. We just shifted our home but when we set up the computer, the CPU was working but the screen was black. We tried restarting it, with the same result. So we plugged the monitor to our laptop, and the laptop screen showed up on it. It means the monitor is fine.
Please tell me what should I do!

Tell me if I'm missing one.
It is an Acer S231HL bid monitor.
Is the mouse active on the black screen? Do you hear the initial beep sound when you turn on the PC?

Open your PC and confirm that all cables are firmly connected.
