Our NT 3.51 + SP4 WKS has been running quite happily for a few months. Over the weekend, the BSOD popped up with a STOP c0000218 Unknown Hard Error. I tried re-booting the system - same again. I tried repairing the system using the ERD - same again on rebooting after the repair.
On cold re-starting, the system memory checks ok. It runs the bootloader ok, NTdetect ok and OS loader V3.51 ok. It does its disk check (three dots) and appears to be about to through up the GUI when it falls down.
Any ideas as to the possible source of the problem?
