I've now got a zipped "Complete Memory Dump" and "Eset Log Collector" file. The "Complete Memory Dump" is 1.7Gb in size so will upload that somewhere as soon as possible. Looking at the "Complete Memory Dump" using WinDBG it seems this may have something to do with the "Sage Accounts Control Service V27" service, which stops responding 7 seconds before the BSOD every time it has happened which is 7 times today!
