Hello, excuse me if I take advantage of your post. I have the same GPU and yesterday I decided to upgrade drivers to 18.1.1 but I had some troubles too.
Mainly about the installation progress which, at certain point seemed to stop, and it's not the first time that happens. At the second try I got the flickering screen then the system rebooted and my hdd disappeared (but I'm not sure that's related to this, since I made some changes inside the case a short before and probably I touched the cable). Anyway, I had to try 2 or 3 times before completing the installation and now it seems all right except that I keep having crashes while in game, I got the same result even when I tried a stress test (random colour screen, freezing sound, no signs of life, so that I have to make a hard reboot.)
It's about a week that I own this GPU, so I don't know it very well...
GIGABYTE 970A-DS3P FX
XFX RX 560 4 GB
8 GB RAM
Windows 7 ultimate x64 SP1
PSU Tecnoware 500W but since I fear it's too poor for my actual equip, I'm waiting to replace it with a TQXGEII-700SAP 700W.
Moreover... what is ##ID_STRING17##? It's appeared in Start menu after installation, under a folder named ##ID_STRING16## .
