I own a AMD machine running Windows 8.1. The 290 I own has run well for the last 18 months but I'm ready to upgrade. I uninstalled the Catalyst suite and 290 drivers, remove the 290, plugged in the 390 and powered up the machine, but then the OS goes into a tailspin of repeated failed boots. When I boot the machine into Safe Mode, the device manager is still reporting the 290 and fails to detect new hardware. Similarly, attempting to install the Catalyst suite or chipset drivers fails to load detection drivers. Is there something that I'm missing? I'd like to get this GPU running without dropping a pile of cash to take it to a computer repair store.
