I am running Debian v-8.4.0 and have encountered a problem with my

crashed due to fan failure about a month ago. I automatically set up
the internet connection during the installation and it worked until
several days ago when I had need to reboot the system.

Now, however, the internet connection is not started on booting the
system and it is necessart to run 'dhclient eth0' as root.

ifconfig returns:

Further, /etc/NetworkManager/system-connections/Wired Connection 1 is:

[connection]
id=Wired connection 1
uuid=53ac3b1f-4121-41d3-a303-45b1b75577e9
type=802-3-ethernet

[802-3-ethernet]

[ipv4]
method=auto

[ipv6]
method=auto
ip6-privacy=2

I am, however, loathe to edit the file as I don't know what I would be
doing.

A solution to the problem would be much appreciated as my wife uses to
compute for Ebay

Thanks in advance.

It sounds like either dhclient is not running as part of your boot process, or it's running too early in the boot process.

Since you mentioned you are running 8.4, which is Jessie, I assume you are running systemd. That being the case, run as root:
journalctl -b > log.txt
And post it somewhere we can see (it could be long) so we can see what happens when / if dhclient is run at boot. You may want to look through the log for dhclient relevant stuff if you don't want to post the whole thing, or go through it removing personal stuff eg fixed ip addresses, as posting the contents of the boot log can sometimes be a security risk.
