I was playing Ocarina of time, when an error came up. I checked my video card and it was disabled (?). So I enabled it. I restarted, then it was still off, but it said it was on. There was some error. I restarted again, and when it gets to the login screen, and beyond, it's nothing but black, but you can still do stuff..... If I get a new card, will it reset my harddrive?
