Do you need help fixing a black screen on a desktop computer? Here is what you can do to resolve the issue.

1. Check to see if the computer is on so that you can confirm that the motherboard is powering the video card and thus transmitting a signal to the monitor. Lights on the power button or noise from the fan will confirm that it is on.

2. Check to see if the monitor is on. A (red, yellow, green or blue) light on the lower right corner should be illuminated to notify you that it is indeed on.

3. Check and tighten any power and video cables for the monitor. If these cables are loose, it will cause the monitor to not function properly. Remember the cables has two ends so check at the monitor, computer and power strip.

4. Check and test the setup button on the monitor. If the menu window does not appear, the monitor may be bad or need to have the power cable replaced. If you do see a menu window on your monitor, it signifies that your video cable or non-integrated video card may need to be replaced. If the video card is integrated onto the motherboard, you will have to add an aftermarket video card once you determine the integrated video card is the culprit.
