I was on my computer and then it froze. I restarted it, and when it restarted, nothing came up on the screen. I plugged it back in but nothing, stayed black. The monitor is still good because I can feel static and the green light is on. I re-inserted the card (not sure the name, where you plug the monitor into-blue plug-in) and turned computer back on. The computer was running but monitor stayed black. I tried another monitor and that one stayed black too. Does anyone know what's wrong? Sorry about posting this twice, the first post wouldn't come up.
