My computer was working fine, I went to get something to eat and then when I come home my monitors (2) are both black and my razer keyboard and mouse aren't displaying their colors but my computer is still running. I shut off my computer and restarted, to no avail my monitors displayed nothing. I have unplugged everything except 1 monitor and tried restarting but still nothing is displayed. My computer starts up fine, the fans, graphics card, lights, everything starts up fine but my monitors, keyboard, and mouse stay black. I have no idea what's going on
Look around your computer and make sure nothing is loose. Check the inside to see if any of the USB wires are loose or if your cable for your monitor is loose.
