It has recently started crashing part way during startup and then doing a "power fail reset". It then restarts in Safe Mode.
The problem appears to be related to my Norton Virus program. If I start up in a step by step process when it wants to default to safe mode and then prevent the following file from being run - SYMTDI.VXD - it starts up OK.
Anyone any idea?
P.S. Something that puzzles me is that I have had this before several times and it was then fixed for a while by performing a disk scan and defragmentation.
