The messages are not consistant. Now I can boot to Safe Mode and no Explorer messages or blue screen. I did manage to run the DUN14-95 file, rebooted 'protection error' msg again. I'm a bit rusty on windows, usually use *nix, but does it matter if I warm boot or cold boot on restarts ? Also, the computer I'm using has a number of drives in it, as I use it to multi-boot. But win95 won't worry about that, I think, it will just see it as a HDD. Peter
