the GUP card does not work

I encountered

graphics card to repair the problem is that the host did not start, and you listen to is not a long call A voice that is a memory problem is to get an out call, and that is the problem graphics, but also you look at the keyboard light is not bright, according to the NumLock key to whether or not a bright light, would prove Host is opened, the problem is the graphics display data line ..there is no problem now, there is no information transmission
