Last night my computer runs well without any problem. But the next morning it suffers a problem which I state in the title. I check the brightness and contrast settings,but nothing happens.

See if the cable from the motherboard is correctly connected to your monitor.

Does the monitor give any error message when you switch it on after detatching the cable from CPU?
