Hi psdsdrew,

I appreciate your efforts to provide a detailed description of the issue and the steps tried to fix it. I suggest you to update the video drivers and check if you can obtain a display on the monitor via the DVI interface. You can download the latest drivers from the following link by punching in the Service Tag and by clicking on the "Drivers & Downloads" tab:

You may also check if the monitor is working properly by checking if it displays color bands on the screen when all the data input cables are removed (E.g DVI and VGA or HDMI cable).

Please let me know about your findings and attach a picture of the rear panel in your reply if the issue persists.

Thank you DELL-Rajath N, I am at work right now but I will download the latest drivers when I return.

Where can I find my service tag?

The monitor works fine, the color bands do show up on the screen when there are no cables present.

Hi psdsdrew,

Thank you for your reply and for providing an update on the status. The Service Tag is a 7 digit alphanumeric code located on the white bar coded sticker on the back panel of Alienware X51.

Please let me know about your findings.

I dl and installed the nVIDIA Graphics Driver and Intel Graphics Driver and will restart my computer now

I just got home and my computer has connected to the monitor, it said their was an error. I am installing and updating the video cards as we speak. Then I'm going to restart my computer and hopefully it will work

Everything seems to be working fine, but i will update you tomorrow. Let's see how she behaves in the morning.

It's doing it again, no signal is sent to my monitor...What next?

Hi psdsdrew,

Thank you for your reply and for providing an update on the status. I suggest you to uninstall the video cards from the Device Manager along with the driver by checking the "Delete the driver software for this device". Restart the system and install the latest drivers again.

Please let me know about the status along with a picture of the back panel if the issue persists.

I cant locate what to uninstall? Is it he Intel (R) HD Graphics?

Hi psdsdrew,

Thank you for your reply. Yes, it is the Intel HD Graphics and any other graphics devices listed. Restart the system, enable the device again and install the drivers.

Please let me know about the status.

the back of my x51

might be reversed

Well now I bought a DVI to HDMI Cable. When I returned home I turned on my computer and it began to malfunction. My computer starts up for 1 sec then turns off, waits about 4 seconds then repeats the process over and over non stop. No signal is sent to any of my monitors. The computer doesn't even show the start up logo. I just keeps turning on and off on its own.

Hi psdsdrew,

Thank you for your reply and for providing an update on the status. I suggest you to remove all the cables, peripherals connected to the back panel as shown in your picture. Press and hold the power button for 20 seconds and release it. Reconnect the cables and power on the computer.

You will need to remove the graphics and check if the system power on or with one memory module each time.

Please let me know about your findings.
