Hi, 

Are you using a Dell monitor with the system? 

In order to assist you in a better way, please let me know the model# of monitor.

You can also run a monitor self test on your monitor following the steps below:

• Turn the system and the monitor if the system or the monitor is in off state.
• At the back of monitor there are two cables connected to it.
• One of the cables is coming from the rear of system tower which is the data cable and the other is the power cable connected to the wall jack.
• Please, disconnect the data cable which is connected to the rear of system tower but do not disconnect the power cable.
• After few seconds there will be a box with multiple colors moving around the screen which would mean monitor is working fine.
• If you do not see that colored box then there could be an issue with monitor of your computer. 

Please reply with findings.
