Facing issues with BSOD on PC in Emsisoft Anti-Malware Home Posted May 19 · Report reply @MJmusicguy - when the OS dumps, it has to write a copy of everything in the in-use memory, to disk. It's not safe on a system that's hurt to use usual files for that (the file system may be in a mess because of whatever has gone wrong) so the OS instead writes the info to the pagefile (which is a private file only ever used by the OS). When the OS is rebooted the dump data inside the pagefile is then copied out and put into C:\WINDOWS\MEMORY.DMP It follows that the pagefile needs to be big enough to hold a LOT of data. You maybe don't normally have a very large pagefile, but to allow this dump process to work you'll have to make a big one. On the webage about pagefile changes, do you see the screenshot at "F" in section 6? Follow the instructions to get to the same place on your system and screenshot it or make notes of what it says - how many drives, what sort of pagefiles any of them have, and tell us what the values are. Don't change anything for now, just Cancel out of that pane.
