Thank you carwiz
. So I've updated the paging file size like so:
Curious, do I need to set both the Initial and Max at 1024 or would adjusting Max alone be sufficient? And... should I put a paging file on my HDD (listed as D: REX in screenshot).
Hopefully this solves both SYSTEM_SERVICE_EXCEPTION (3b) and MEMORY_MANAGEMENT (1a). Will keep udpated if any errors / BSODs occur.
