Blue Screen of Death - From the deep levels of hell

I have the worst BSOD I have ever seen. The biggest problem here is that it's intermittent. The BSOD happens a couple times per day The system is totally fine in between. There is no specific event or task that triggers it, seems to be completely random. The error, driver, and parameters are different every time.

This has been going on for weeks. Here are the items tested so far:

Motherboard - swapped
Processor - swapped
Memory - new
Harddrive - new
All USB (except k/m) disabled.
OS reinstalled
Non-essential services disabled.
BSOD occurs in safe mode
Video card - swapped
All temp/fans working and within range

This is a Windows 7 machine - Intel chip, ASUS board.

Here are a few of the most recent BSOD logs:

Changed per superuser question on how this differs from a general question about bsod's

PAGE_FAULT_IN_NONPAGED_AREA, MEMORY_MANAGEMENT and PFN_LIST_CORRUPT are all most certainly RAM problems, new sticks can still be defective, it's actually quite common.

You can run MEMTEST, try removing all RAM sticks except 1 at a time to figure out which one (or more) is the culprit. Or simply request a replacement from the retailer.
