Hi. I just updated my graphics card driver after doing a factory reset on my laptop. I have installed the correct drivers from the AMD Website. I have an HD Mobility Radeon 5730. Now when I boot the screen shows the asus bootup symbol and the windows start up, but then goes black when its time to log in. If i plug in an HDMI cable I am able to display the image to my TV with no problem. Does anyone have any idea how to fix this?
