Complete noob here wanting to run a full node but having errors.
Bitcoin Core: v0.151
Operating System: Windows 7 Ultimate 64bit
PC: Intel Core2Duo 2Ghz, 4Gb RAM, C:\ 14.3Gb free, D:\ 255Gb free, E:\ (DVDROM), F:\ 353Gb free (External USB - Bitcoin Core and data are installed on this drive), G:\ 809Gb free (External USB drive)
Problem: dialogue box "Error: A fatal error occurred, see debug.log for details"
This error came up one first run of the software when synching the blockchain. It has come up again after re-booting and restarting.
