I recently upgraded my machine to Windows 10. I have an AMD Sapphire HD 7750 card in the box. On the first upgrade, I had no problems with the machine. Around the end of August, new updates came from both Microsoft and AMD. It's at that point that I started to have problems - specifically, the box boots, shows the Windows logo for a while, then goes black and does not boot fully. I've completed removed the AMD drivers and software and can get the machine to boot. But once I try and install the 15.7.1 or 15.8 drivers the same thing happens - machine won't fully boot and sits at a black screen. Can anybody at AMD tell me what's going on here?
