Well, some of those BSODs I think were resolved by other things. For instance, when I updated my network drivers the athrx.sys BSODs stopped and when i reinstalled my audio drivers the cmudax.sys BSODs stopped. When I reseated the RAM, cleaned out the DIMM slots, and reset the pagefile the PFN_LIST_CORRUPT errors stopped. This is what I mean when I say that it keeps coming back.
It acts as if the problem was resolved but then something else starts crashing it a few days later.
