Hello, I have a new GeForce 8500 GT video card and was trying to hook up the computer to the TV to watch movies. For some reason, it was not working and I tried several different configurations offered by the Nvidea control panel. Apparently I pressed the wrong button because my screen went blank and there was no picture on my TV. I tried "escape" and a host of other buttons but nothing worked. I rebooted and I have a picture on my monitor until the Windows logo appears. After that, the screen turns black and the light on my monitor turns from green to yellow. I think the video card is just sending the picture somewhere else, but I can't change the setting back again because my screen goes black after the windows logo. (I'm typing this on my laptop). There is no problem with the video card because I was gaming on the system yesterday for a couple of hours with no problem. This problem only started when I tried linking the computer to my TV. I am hoping there is a relatively easy fix to this. Any help would be greatly appreciated! Thank you!
