I am no pro at this, but certainly a great troubleshooter. I believe without clear evidence that this is an incompatible set up. Possibly the video card choice. I am getting "driver not intended with this platform" when it is trying to install the wrong drivers "Ati firepro V instead of R7 250" I am going to try another video card later. This has totally been the BSOD nightmare though. Nothing that running in safe mode and uninstalling all video drivers wont cure. *Note* I did get the R7 drivers installed once with a hard drive PSU but it would not use it. I have since cleared all the hidden drivers out of my device manager though. I'll try to keep this up to date to save someone else the trouble I've been through and hopefully not give bad info. *I am using a 450 W PSU: 400 W required for that card*
