The first thing to do is identify what issue you need to resolve.
Does the LED on your monitor change from yellow/orange (no signal) to green? If it stays yellow, you need to check your video card. Remove it and reposition it in place. That is a hardware issue.
If the LED turns green, the monitor is getting a signal from the computer but if you do not get a startup screen, you may have a software issue.

I have a Samsung monitor, but the light does not change when turning G5 on..
It has worked flawlessly for a long time, but one day it just wouldn`t turn on.
Have now taken videocard out and put back again, but no change.
