Hi Pse, wow, what a long post 
AV apps tend to stress the filesystem, the harddisk controllers and the memory, so that may have triggered the BSOD
I second that. I’ve seen a number of crashes (crash dumps) where an AV was the main suspect but at the end of the day, it was concluded to be a HW problem. The crash was indeed near the AV code but that was only a coincidence - not much of a surprise though as AV’s are usually one of the most active pieces of a system [unless a complicated model is just being rendered in 3D-Studio ;D])…
Those errors might be linked directly to the memory (as a Page Fault in Non Paged Area is usually caused by a driver that doesn't have enough physical memory, right?).
Not really. The real cause of PAGE_FAULT_IN_NON_PAGED_AREA is usually quite difficult to debug. In most cases, it is simply a driver error. A driver uses a pointer (accesses a memory location) that is invalid. True, in some cases, this may be a hardware problem - but usually not. In any case, the system should be able to handle low-memory conditions without a crash!
Actually, given a full crash dump, I have some tricks to tell you (with a reasonable degree of reliability) whether the problem is caused by a faulty (or low-voltage) RAM or not…
Cheers
