I am aware that many people are experiencing similar issues, I figure I would just add to the pile. That, and my issue does have some differences.
Card abruptly started experiencing a black screen issue a few days after upgrading to the radeon software adrenalin 18.2.3 driver update.
System often will display green or yellow graphical corruption, sometimes even in the Bios screen. Once system has booted into Windows, the screen will randomly turn black and the system will become unresponsive. Sometimes a BSOD error will occur citing atikmpag.sys as the cause of the error, other times the screen will simply remain black. In some cases the GPU fan will ramp up to 100% making tremendous noise. I do not need to be running a game or 3D application for this issue to effect me.
Attempting to use DDU to uninstall drivers and rollback to previous drivers have no effect. Have tried 18.2.3, 18.2.1, 17.12.2, 17.12.1, and 17.9.1. All experience this issue.
Disabling the Display Driver in Device Manager in Safe Mode and then restarting stopped the graphical corruption, as well as stopped the black screening, however this leaves the graphics card unusable for 3D applications. The fact that the card no longer causes errors when drivers are disabled or uninstalled leads me to believe this is a driver or, more likely, a firmware issue.
I have seen instructions for fixing BSOD issues concerning atikmag.sys that involve unpacking atikmag.sy files using CMD prompt, then copying them to the windows system 32 folder, however this has not worked.
Some people have had success using wattman to help resolve similar issues, but my card does not support wattman.
When i attempt to run DISM, I get an error message: The restore health option is not recognized in this context
This is such a terrible time to have a video card fail as well.

edit: as soon as i reported this to AMD I started getting the graphical corruption even without drivers installed, so maybe it's not a driver issue, maybe my card is simply failing. I decided to buy an Nvidia GTX 1060. It barely qualifies as an upgrade, and it cost me $350 but I can't afford much better. In-fact, I really can't afford this, but I need a working graphics card, and it doesn't sound likely that a solution will come about any time soon. If anyone has a solution before I open the card, it will arrive Friday, then I'll send it back for a refund, cause I really need the cash.
