I have been experiencing issues for a while now, since I upgraded CPU, motherboard and memory in one go. My system worked fine prior to the changes, and after a full reinstall, I've been having frequent issues with BSOD. My system is currently; Intel i5-3570K Ivybridge Asus P8Z77-V LX Motherboard 2x 4gb Patriot memory Radeon HD4870 Windows 7 Professional 64bit Service Pack 1 250 GB Sata Western Digital Hard Drive (Windows installed on this drive) 80GB Sata Western Digital Hard Drive Samsung SyncMaster 226BW monitor @ 1680x1050 LG Flatron W2242S Monitor @1440x900 The BSOD messages I am getting are "Paging fault in non-paged area" and "Video Scheduler has experienced an unexpected fatal error" I've searched across the internet, and there doesn't seem to be a link that I can find between the two. The BSOD occurs most often when I am playing a game (normally World of Warcraft) and watching flash based video in my second monitor. Recently I have been playing a number of single player games, and therefore only have applications running in the main monitor, and have no problems with BSOD, it only seems to be while utilizing both monitors I have an issue. Obviously, ask if any more info is needed.
