Hi all. I know there have been previous posts on this topic, but none have solved my problem. I was buffering a movie to watch and had left it paused full screen while I went out for a few hours. On return the screen was black and there was no response from mouse clicks, esc hits, or any other inputs. I shut down the comp holding in the button for 10 seconds or so. Now, every startup, the screen is black expect for a quick flash of the windows load screen. I've tried the graphics card and monitor on another computer and they are fine. I've blown out all the dust with an air can too. I can't get to a safe mode screen either or rather, I could, if I could see it! I won't be able to restore to an earlier time, if that is offered as part of a solution, as I don't have any earlier saves. My computer is a HP Pavilion m7480n desktop with a GeForce 6800 ultra graphics card. It runs windows xp with all the service packs. Please help!
