So about 2 months ago while using my PC the computer suddenly crashed to a black screen with orange lines going vertically through the black screen. I was unsure of why this would happen and through the help of Tom's Hardware myself and others concluded that my video card had failed. I purchased a new card and hooked it up and alas nothing happened. There is still a blank screen and nothing happens. Then thorugh the help of others concluded that it was my motherboard all along. I got a new motherboard just hooked everything up and still there is nothing. The pc turns on fine and there seems to be no visual problems but still nothing comes onto my monitor. I have tried DVI cables and HDMI that I know work properly. Any help?
