Every time I attempt to login it fails just as the login screen is about to give way to the in-world view and I get a message telling me something to the effect that the graphics driver and the open GL driver no longer communicate. Friends are able to see my avatar but I can't log in to control it. I wait until it poofs, try again and get the same fail message. I have reinstalled my graphics drivers several times to no effect. My computer setup is: Pentium-D 3.4gHz, 3gB RAM, Nvidia GT440 w/1gB RAM, Intel D945PVS motherboard. Strangely the same graphics card was able to log into SL on my friends' computer with all features enabled including lighting, shadows and D-o-F although it was a bit slow. Update #1: I just managed to log in at Low settings with all features turned off. Everything looked very blocky. What can I do to use the regular features that I used to be able to use with my old Nvidia 8400 GS? Update #2: I was able to log in with everything set to high w/ anti-aliasing @ 4X but had to have basic shaders switched off. The moment I attempted to enable them I got the video driver to open GL driver fail message :-((( BTW, the crash logger fails every time.
