Hopefully someone will be able to help me as I am coming unravelled trying to fix this problem.
I built this PC myself and it has run without issue for months, up until a week ago. At that time I started receiving random BSODs although only when the computer was not being used actively (i.e. I'm not at the keyboard). I can play games for hours or browse without issue, but if I leave there is a good chance of a bluescreen when I get back.
Most of the bluescreens have been MEMORY_MANAGEMENT, although there have been a few PFN_LIST_CORRUPT as well as my personal favourite, IRQL_NOT_LESS_OR_EQUAL also making a guest appearance.
I have run Memtest overnight (10+ passes) with 0 errors, as bad RAM was my first suspicion. I have run extended tests on both of my hard drives using SeaTools and neither one had any errors (or any SMART warnings).
If anyone could take a look at the dumps and give any further advice I would appreciate it, since I am close to being out of ideas.
