Envy had errors when removing and installing new nvidia drivers

Hello

I started with a problem of the composite (RGB) video output missing the red color (faded blue screen) with the Nvidia (nvidia-gtx-new) drivers. My system consists of a MSI K9NGM3 motherboard with 2 gigs of ram. The on board NVidia 7050 chipset is great for HD viewing. This motherboard was capable of 1080i/p output via the VGA and the HDMI connector. The component was the only problem being washed out but had the 1080i resolution. I wanted to use the component out for use with my 47 inch TV until I picked up a HDMI cable. I was told to install Envy which I did. After the install, I ran the program. In the pop-up terminal, it showed that during the uninstall of the original driver it had errors. At the end of all of this I am now stuck with 600x400 or 800x600 video with a generic card driver. I tried to reinstall the nvidia-gtx-new driver that I installed some time ago, and it will not, or I suppose it did not reinstall. I am still stuck with the low resolution. Any way of fixing this without pulling Ubuntu from the drive and starting over. Any help would be greatly appreciated.

Thanks
Gary
