Cannot display onto external monitor through RGB output anymore

[Darth Menace]

Hello, I often put my display on my TV to watch movies, etc. It's really handy and I just plug in my RGC cable and go from there. A few days ago I was streaming the Olympics onto my TV and my computer stopped displaying onto my TV. For a while I thought it was my RGB cable, but I tested it on another laptop and it worked fine. I deleted the display drivers and re-installed them so they are all up to date, but when I plug in the RGB cable the screen goes black. When I go to "Connect to a projector or other external display" where usually there are settings to change around it won't let me do anything because there is no external display attached, but if i do attach it the screen goes black.

I guessed it was NVIDIA messed up so i go to their website and they say I have to download it from the Toshiba website, but there is no NVIDIA driver for my computer.

Any help or suggestions would be appreciated.
