Hello. So back at the very beginning of October I started getting blue screens. I've 7 since then (possibly 8, may have been one during the night but I'm unsure). It's always PAGE_FAULT_IN_NONPAGED_AREA and mentions MDFSYSNT.SYS. I never really took note of what I was actually doing when they occurred (haven't seen once in many years and they've all given me quite a shock) except or the most recent three that I witnessed; each time I was either moving, editing or deleting a file. Just random files in Pictures or Documents. Not sure if that's important or coincidental. I've also added in two photos I took with my phone of the actual screen, I doubt they add anything useful but thought I may as well. For whatever reason they most recent 2 (or 3, if there was an extra one last night) did not create dump files and the usual window that pops up after rebooting didn't appear. I've done some searching but I'm pressed for time and there's a lot of different information that can be overwhelming. I've followed the instructions in the "How to ask..." thread, but if there's any other information needed please let me know. Thanks.
