I have a laptop named HP Pavilion g7 Notebook PC running Windows 10 x64 legit and have 2 GPUs, ATI Mobility Radeon HD 4200 Series (slow redering) and AMD Radeon HD 7400M Series (fast rendering)
I upgraded my laptop to Windows 10 x64. All drivers are working perfectly but there is a problem. The device AMD Radeon HD 7400M Series has stopped working with error code 43 and the HDMI is not working. The problem occur on Windows 8 and 8.1 x64 too. Everything are updated from Windows Update and the graphics driver with AMD settings were installed itself.
I downloaded the correct graphic driver (Windows 8 x64 version) from the HP manufacturer but it does not work. I can't download drivers for Windows 10 because they said, their drivers are avaliable in Windows Update. Also the graphics driver is also not working with Windows 8.1 even the driver was made Windows 8/8.1.
I uninstalled the graphics driver (AMD Radeon HD 7400M Series) from Device Manager and AMD catalyst software, rebooted my laptop with signature driver check disabled and run AMD driver settings as an admin with Windows 7 compatibility, but not working. I uninstalled the graphics driver and scan for hardware changes, and few minutes later, the driver was installed and windows says it is working fine, but the HDMI still not working. Softwares still using slow GPU ATI Mobility Radeon HD 4200 Series and the video playback still lagging a lot.
I had updated the BIOS to the latest version before i install clean Windows OS. AMD Radeon HD 7400M Series works perfectly on Chrome OS and Windows 7 and video playback is very smooth so it must be a compatibility problem on Windows
Here are the screenshots you can see
