1. Try unplugging and reattaching the power cables. 2. Try swapping power cables for your monitor and your computer tower if they are the same. 3. If the above steps do not work, most probably your monitor is busted. Try to get it replaced/repaired if it's still under warranty.
Compaq's are notoriously under powered. You should take a look at the power rating on your power supply, then cheque the necessary voltage for the card. Also make sure that the card doesn't have an extra power connection that you need to fill to make it work.
Well as you have already tried disconnecting the peripherals from your computer, and tried restarting the computer too which did not help you, it sounds to be an hardware issue with the monitor. However if incase you have not tried this, you can disconnect the monitor completely from the tower, power on the monitor, if it powers on and you get a message as no signal, your monitor is working good. If not replace the monitor. If the message appears on the monitor screen, disconnect everything from the tower, push and hold the power button on the tower for a minute. Connect just the monitor and check for any display. If you do get display, thats good, connect one device at a time and check to see if the display appears.
If theres no display with just the monitor connected, the issue would be with the graphics card. You may need to replace it or get the system repaired.
You would have got a CD with this moniter..
we ahve install that cd..
and its better to check the cables first which would be the
VGA CORD that is blue in colour which connects your moniter with the tower.
We can check the connections with the moniter for the Tower and then install the cd.
