Hello,

Going to AMD won't help. I tried to install from AMD as well and got varying results but always failing on Display Driver and HDMI Audio. The following two didn't work for me:

amd-catalyst-15.7.1-win10-64bit.exe
amd-catalyst-15.7.1-without-dotnet45-win8.1-64bit.exe

However, the following Dell drivers install without a hitch:

Video_Driver_KRV3R_WN32_14.502.1005.1002_A07.exe

I think it'll be a wait time for AMD to actually put device ID's into the catalyst software. I'll make a bug report.

Also, funny thing is before I tested Win 8.1 to Win 10 upgrade, Dell website stated:

"Windows 10 upgrade available.
Dell has tested this product to confirm that it can upgrade to Windows 10."

Now, after Windows 10 is running, on Dell drivers page I get above plus:

"Windows 10 Operating System not supported for this device
Dell does not support the Windows 10 operating system with this device. Some Windows 10 compatible drivers may not be available on this page. "

Ha, ha. It'll take some time for all these to get sorted, but all Win 8.1 64bit drivers work. The only 3rd party drivers I've installed that are not Dell are:

win64_154004.zip (Intel, Video Driver 15.40.4.64.4256)
Wireless_18.11.0_s64.exe (Intel, WiFi Driver)
WP-BT_17.1.1504.01_e164.exe (Intel, Bluetooth Driver)

Also, I didn't have luck installing Free Fall Protection driver, but my Device Manager is clean (no question marks).

Hope this helps anyone.

I also tried installing Video_Driver_KRV3R_WN32_14.502.1005.1002_A07.exe, but then got a black screen after login (the screen appeared after a minute or two).
