My computer was recently repaired with a new motherboard, and a nVidia GeForce 9800 GT video card. Now I am getting kicked back to my desktop, sometimes after an hour of being in SL, sometimes after 15 seconds. Might be a problem with settings on the graphics card, but I am not sure what the proper settings should be. It only seems to happen with virtual worlds, like Second Life. I have checked out the heat issue on the video card, and it is fine. I have also deleted all my chat and IM logs, but that made no difference. I have a feeling that it is a settings conflict, but I have no idea about how to resolve it.
