Should anybody ever look at this thread, the solution was hardware, the exact component at fault as yet undetermined, but almost certainly either a Mobo problem or a failing power supply. I eventually decided this was an excuse for a hardware upgrade, bought a new barebones system and took across the drives and graphics card (the Radeon one) from my old PC. There have been no problems since then. Brian. -- ubuntu-studio-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
