What may be of significant info is once my system shut it self off last time and I turned it back on again - I noticed the back-light on my Logitech G110 keyboard and G9x mouse didn't light up during boot as normal. I unplugged both for a moment and reconnected - I haven't had another incident since yesterday...

I remember this occurring to my keyboard back-light during my first bout of random system shut offs and after updating my video drivers I did unplug my keyboard and re-connect (which I forgot to mention) - could a fault with my keyboard/mouse be forcefully shutting my system down?

So... after using a different keyboard, my system is still randomly shutting off! At least I can rule that out though

On the last couple of occasions some shut-off were mid-way through playing games, I've had HWiNFO64 combined with MSI afterburner to display GPU and CPU temps whilst gaming for around an hour and my temps were all well within safe limits!

I decided to run Windows 7's Error-checking tool on my HDD incase that was to blame? I set one up to run before boot to automatically fix file system errors and to scan for an attempt recovery of bad sectors. Strangely enough my system shut off shortly into stage 4 of the process. I have a Samsung HDD and downloaded and ran a Samsung Tool for scanning and diagnosing issues with the HDD before boot, oddly my system also shut off shortly into the scanning process.

I scheduled another Windows 7 disk check to run later on and it managed to complete - after looking at the log in windows there were no bad sectors mentioned or anything but it did still say at the end 'Windows has made corrections to the file system.' However my system is still randomly shutting off!

As it managed to shut off during disk checks before the OS loaded, am I right in saying its a hardware issue and not anything software related? I need your help diagnosing what's up with my system soon as I'm about to resume my University studies and need a stable system to work from! Any help at all is greatly appreciated!

Here are my most up to date logs to assist you guys!

First, you can not rule out software You can not rule out hardware. I wish life was so simple.

Does the samsung disk check program run within windows or do you burn the program to CD and run the program from CD?

Haha, oh - I also now wish life was this simple!

It's something you download and burn to a CD which you then run at boot. It's something I'd had a while and used a long time ago. It doesn't seem to be prominently documented on Samsung's website no more - it looks to be the 'ES Tool' mentioned here.

When I ran it a long time ago it was on the very same drive to scan for any issues and everything was A-Okay.

That the system hung while running a disk test is not a good sign, regardless of your chkdsk results.

On each and every "drive" on your hard disk, run:
chkdsk x: /R

where you substitute the correct letter for X:

Don't worry about capturing the results.

When you are finished, I'll give you a script to run which will give us the info from all chkdsk commands that you have run.
