I can't find any minidump files or even the location. I've ran the windows memtest twice now, and it returned results both times saying there's nothing wrong. I've encountered three bsod's over the course of the past day, including two cases where I had to restart my pc due to nearly every program I had running crashing and giving errors and numerous alerts. Very strange. I want to rid of these issues asap, so help is extremely appreciated.
Here's pictures of all three bsod's in order of when they occured:
