On my 270e I was getting BSODs once I got into Windows, memory management, system_pte misuse. I tracked it down after some Googling to maybe having my external hard drive attached. This is pretty odd behavior I think, I never had to disable that setting before.

So careful with external drives, you may need to disable Legacy USB.

Legacy USB devices always cause conflicts on these new platforms (Z170 and going forward). Sometimes during post and other times inside the OS.

It works with a USB 2.0 memory stick because that's how I updated the BIOS and installed Windows. However it gives me BSODs if Legacy is enabled and I attach my USB 3.0 external drive (front panel connector.)
