[SOLVED] - Major Maui Meltdown.

Re the filesystem problems you mention, i'm sorry but i am not knowledgeable enough to know what i should do about those. 

Can you manually run a sudo fsck.ext4 /dev/sda3 to check if it spits out any error message.

Thank you for your various answers. Of necessity there will be delays between my various responses; it will take me some time to try each thing. Hence i will be supplying a series of responses, one issue at a time.

Code:

Z97-HD3:~$ sudo fsck.ext4 /dev/sda3
[sudo] password for moi:
e2fsck 1.43.1 (08-Jun-2016)
/dev/sda3 is mounted.
e2fsck: Cannot continue, aborting.

/sda3 is my encrypted /home partition; did you really intend that one? I did also try /sda1, ie, root, but received the same result [of course]. I hope you didn't actually intend me to try this instead from a live-media boot, coz whilst then my real partitions would be unmounted, i won't have access to /home due to its .ecryptfs encryption.
