Running Windows XP SP2 on a ThinkPad G41, has non-integrated nVidia GeForce FX Go5200. Whenever I install the driver for the video card, the LCD shuts off. I tried using the IBM driver from their site, the nVidia Forceware driver, and the Forceware driver with a modified .inf file. Using the IBM service partition to reinstall factory settings doesn't even allow XP to install successfully. I have to manually install XP. I just replaced the video card to get the Laptop working again before the driver troubles. I theorize that I replaced my bad video card with a slightly broken video card. Can anyone confirm this or come up with other possibilities?
