I have upgraded my cpu, motherboard and case. Now my monitor(futura) displays please check signal cable. When I hook my system to another monitor(viewsonic) it works. I even hooked another computer system to my monitor and the monitor works. So I'm going crazy trying to figure out the problem. And I cant have the other monitor, its my husband
i've had this problem before, check the seating of your video card and make sure its screwed into the back of your case. make sure you screw the cable in tightly. try holding the cable and the vid card at the same time and applying pressure to them if the above doesnt work.
Might be a refresh rate or resolution setting that you have your system set to now that is keeping your monitor from displaying anything. Try connecting your system to the Viewsonic monitor again so you can see what you are doing. Go into your display properties and set the resolution and refresh rate to something that you think it will handle. I suggest 640 x 480 60 Hz to be safe. Plug the other monitor back in and see if it comes on. If it does then you can set your resolution and refresh rate back up to your normal settings or those settings in which your monitor will handle.
