From a personal experience here. My son has a AMD GPU R9 390. He replaced it about a year ago as an upgrade. The price was better than the nearest NVIDIA GPU specs. So far until his recent driver update.
The latest driver update basically crashed his GPU. We are both very well versed in step we can take to correct just about any issue with a PC. He spent 4 hours the other evening attempting to correct this problem. He tried a clean install of the drivers once in regular mode and once in safe mode. This didn't work. He tried a system restore point, that didn't work. He tried a clean install on two other previous version of the drivers. That didn't work.
Then he started checking around. There is class action suit against AMD for this issue. It appears they bought out another company and tried to adjust drivers to work for both. Needless to say it didn't work.
So far everything we tried has not worked. It appears to fix the issue AMD currently doesn't know how. One may be able to get into the "chip" on the GPU and make changes but there is not clear path for that either.
So currently he is using his integrated GPU so at least he can get on his system. We ordered a new Nvidia 1070. Which for all instances seem to be on back order at a lot of location, maybe due to this issue, unless you order 6 or so at the same time as a package deal.
I would really hesitate if you have an AMD GPU to update the drivers, I would not suggest purchasing one currently (I'm an Nvidia fan anyway). If you do have one and experienced this problem you may look into the class action lawsuit, which we are.
