Don't unplug EVERYTHING. If you know the monitor works then the problem is probably your video card. You should get some sort of image on your monitor even if the proper drivers are not installed. First determine if you are using a video card that is built into the motherboard or if you have a video card that is in a slot. The slot could be a PCI, AGP or PCI-express. If it's a video chip on the motherboard, try to install a new video card in an agp, pci or pci-express slot then connect the monitor to that. (you should at least have a pci slot) If you already trying to use a PCI, AGP or PCI-express card, replace the video card and see what happens.I just took my motherboard and every thing in my computer to switch to another computer case i plug everything?
Probably is the Video Card.





- If the Video Card is integrated to the Motherboard it may be damaged.





- If the Video Card is goes to a ';slot';, verify it's properly conected to the motherboard and the Power Supply (if necessary)





- Also check the RAM sticks to be properly conected.





Hope this helps
