See what happens.
Good place to start. If it boots to safemode but not to normal mode, uninstall the driver and see if it boots to normal mode with standard vga. Then try another driver, maybe even a beta one. Also, check firmware version on the card, maybe the previous owner updated to a goofy firmware version or it needs to be updated.
