I got a old pc that the kids use and I got a old fx5200 also so I was gonna replace the mx400 with the fx5200 but I cant get the fx5200 to work correctly, Ive updated the board drivers and the viedos drivers but it still dont work right, in games the pic gets all messed up. Its justa 4x board so the card isnt working a 8x like it can but it that the main reason its not working right? or is this board just wont work with ths card? I mean it is a old board.
