problem installing a reburbished 5700LE

So I orded a 5700LE and when it came the first thing I did was disable my intel graphis via control panel> system> hardware> device manager then it said "you will need to restart your computer in order to take effect", I put no. then I turned off my computer then I sticked in my 5700LE in the pci slot, turned it back on and i forgot to download the Nvidia drivers so thats what I did next. with the plug still in my intel gfx I went to download the driver, wich was FORCEWARE Version: 78.01, intalled it and restarted, while restarting I switched my plug in the 5700LE but the screen just stays black?? :sad:

this what is says..well you know what it says I forgot.
what did I do wrong?
btw i cant see anything right now with the lowest resolutin in the world! and these retarded colors.

please respond this is my first card!
