I bought a Inno3D 512mb 9400GT and installed it into my computer following the instructions that came with it. When I turn my computer on, the monitor shows a black screen and a flashing yellow light under the power button. The graphics card i had before works with my computer but the new one doesn't. I have run out of ideas and really need help. Thankyou in advance.
