view story

http://askubuntu.com – I bought a used nvidia 7800 gtx card and plugged it in to the motherboard and then plugged the monitor into the the vga portion of a dvi to vga converter located in the back of the card. I booted up and got a 640x480 resolution. I then attempted to install the nvidia 304.37 driver. I now know that this driver has been updated to 304.64. Anyway, I installed the 304.37 driver, restarted the computer, the screen went white and black then dropped me to a command prompt. I have since uninstalled that driver, reinstalled 304.60, 304.64, and attempted a couple of others -- all of which were unsucce (HowTos)
