Also having problems with the latest catalyst update.
After installation I think the gamma went totally off whack... my screen went a purple haze, so I reverted back to 14.3 and then everything went back to normal. This new patch has serious bugs that I have not expierenced before in a catalyst update.
I had the same exact thing happen. During the installation of the windows 7-64bit catalyst, it seemed to be running smoothly until it started installing something to do with AMD SATA. I received a big fat bluescreen and could not recover my hard drive. When restarting the computer, upon reaching windows, there is no USB controls at all. I tried to recover the operating system but it was a dead end for me. This driver build was catastrophic to my system, I lost everything.
This forum is not the correct place for Catalyst related posts.
