Hello. I wanted to install the ssd drive as the main device, and Hdd to replace the optical drive. But unfortunately, my laptop produced a black screen, with the processor running. Removed SSD drive installed Hdd drive everything works. I decided to install the SSD in place of the optical drive, the problem returned. In addition, I can not start boot through bios a flash drive. And on the official site I could not find new drivers for bios. Laptop model amd a6-3400m, bios Phoenix Technologies Ltd. V1.15, 12/05/2011 Regards Ivan Kharitonov.
