Sounds like the power button on your monitor is not on, is the light on the monitor yellow and dim or bright when you start the computer? Make sure the monitor is on. If you hold the power switch in for about 10 seconds the power will turn off. But that is not the recommended way to shut your computer down. Use your start button and log off or close that way. Good Luck.

That more than likely means the video (graphics) card inside the computer is bad. The monitor seems to be ok if it is displaying No Input Signal. Isolate the problem by connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it t the computer. If the Borrowed Monitor displays the No Input Signal then your video card inside the computer is bad. If the Borrowed Monitor works and displays your desktop icons, then your original monitor is bad and the video card is ok.

Can I hook my Mac Cinema HD Display 2005 model to my gateway 420GR? If so, what do I need in the way of an adapter?


Windows PC and graphics card that supports DVI ports with dual-link digital bandwidth and VESA DDC standard for plug-and-play setup. You can check the specification of the graphic card and see whether they support those. For the cable if they are not in the box of the display, you can check the following ones.

Composite connection on Gateway Desktop


They are Video and Audio for connecting device together
  • Yellow = Video
  • White = Audio - left channel
  • Red = Audio - right channel
the connectors on a Desktop PC from the graphics card will be an OUTPUT-possibly labelled TV output, so what ever is displayed on your monitor can also be sent to a TV or recorder etc The connectors on the Xbox are also OUTPUT and designed for connection to a device which has the same connection but for INPUT
Your monitor may have composite inputs and allow you to switch to those Some TVs will have those connections as inputs and you would select one of the AV options to see the signal, often a separate button to choose AV input /HDMI / PC etc Some DVD and Video also have these as an INPUT as video cameras often have that type of connection - to record the signal

Gateway 420gr the HL DT ST DVDRAM GSA 4120B reads and burn CDs /cannot read DVDs inc Restore DVD


It's time to spend $40 to buy a replacement CD/DVD-writer.
There's no way to "fix" your "half-gassed" DVD-drive.
A technician would charge at least $25 to _look_ at your computer.
Instead, "invest" the $25 in a replacement.

Newer monitor to older xp pc


If your monitors are displaying "no signal" they aren't receiving input from the video card. If your PC has two video outputs (onboard) try charging to the other output to see if it will come on. Also reseat your video card in its slot. Also, what can you see that lets you know the keyboard and mouse are not working?
