Hi and welcome.

I am afraid that you haven't given us much information to go on but I think it is probably your PSU that needs replacing. It sounds like it ios not getting enough power to the graphics card. I would recommend something around 750W.

To be honest I am not sure exactly what the green LED indicates as I don't have access to one of these cards to be able to test and say for certain.
