Yesterday I decided to try to update my computer to Windows 10 from Windows 8.1. Waited a year so that known issues could be worked out, which was good because I had blue screens due to driver errors that were quickly fixed. But now I've run into a serious problem with my Radeon R7 graphics card. By way of preface, I had no problems with the display before changing to Windows 10, in fact I've had virtually no problems with the computer at all since I got it.
Specs as I know them:
Model: HP Envy m6-n113dx Notebook PC
CPU: AMD Fx-7500 Radeon r7, 10 compute cores 4c+6G
GPU: Radeon R7 Integrated graphics (not sure about details because I can't find additional info)
The Radeon R7 display adapter simply does not work.
When I tried to open Radeon settings, I got an error message saying that there was no driver installed or the driver wasn't working properly, and the settings app will not open. In Device Manager, there's a warning icon next to the Radeon R7 display adapter, and when I go into details it says that the device was stopped because of a problem (Code 43.) This has occurred with both my original driver and the newest driver available; I tried running Crimson 16.3.2 to update it and it did not yield any improved results.
When I turn on or restart the computer with the Radeon driver installed, the screen is blank on start-up. Putting the laptop into hibernation and waking it up will bring the display back so I can log in, though it is using the Microsoft basic display adapter for display rather than the Radeon graphics (the Device Manager still shows the stopped R7 adapter). After that, the display will sometimes randomly go blank, and I'll hear an alert sound like I just unplugged a USB device. Hibernate, wake up, display is back. It most frequently goes out if I'm doing something with the driver - installing, uninstalling, disabling, etc. - if it's trying to look at or change the driver it's likely to take away the display.
If I uninstall the AMD driver completely, it reverts to the Microsoft basic display adapter. In this condition, I do not experience these problems - the display shows up on start-up and does not blank out unless I try to install an AMD driver. Of course, the graphics are laggy and slow, not good enough to run most things effectively, so it's not a solution to just stay with them, but at least the computer is basically functional and I can go looking for solutions.
I've checked my Event Viewer for any sign of something to help explain these issues. I have noticed a warning from Win32k that seems to coincide with the times the screen goes blank, though I can't tell if it's something that happens when the display fails or happens when I wake the computer up from hibernation. In any event, it gives a 263 error code, which hasn't been all that helpful because the error details don't provide any insight into what it actually is.
I have a system restore point from before I installed Windows 10, so I can go back to Windows 8.1, but I would prefer that to be a last resort, only if the problem cannot be fixed and I have no choice in the matter.
Any advice or insights would be deeply appreciated.
