I've had the worst luck when it comes to computers. Last night I turned off my computer and went to bed. In the morning when I try to turn it on, it sounds as if its booting up normally, and the signall on the monitor led goes from yellow to green, but I don't get any picture on the screen. The monitor is plugged in tightly and everything appears normal. I can't think of anything other than the video card going bad. Any ideas?
