Been at this problem for a few hours and struggling. When I watch a movie/tv/music from a laptop connected to this PC via a simple Windows Workgroup, it will occasionally BSOD with PAGE_FAULT_IN_NONPAGED_AREA. The media is located on a Lacie External HDD. It does not BSOD when on my local drive.

I've run various virus/malware scanners and all is fine. I assume it has SOMETHING to do with my external HDD.
