PC becomes very "choppy", almost unresponsive during high broadband utilisation. Particularly when downloading/updating.

Checked resource monitor and it shows that the disk activity goes to 100% during high broadband utilisation.
I'm using a HDD.

Issue occurs over wifi and ethernet - seems to become an issue once downloading exceeds around 2-4mbps - then the mouse lags, audio choppy and applications take awhile to launch etc (this also affects anything stored on my SSD)

Not sure what's causing it, it's not a certain application, can be easily replicated by using high bandwidth. Neither RAM/CPU reach 100% during the issue.
If I so much as pause a download/update, or reduce the bandwidth utilisation to about 2/mbps then the issue subsides.

There's really a long, long list of potential issues in this. Some examples:

Hardware (faulty hardware / hardware bottleneck / misconfigured hardware resource sharing)
Rogue Driver
Excessive services and/or processes that try to fight for HDD resources at the same time.
Badly configured Page File
Malware
Anti-virus misbehaving
Windows Update being...Windows Update :)

My advice is to boot up. Take a note of all the processes once the boot has sat quiet for 5-10 minutes. Then try to trigger the problem, and see which process(es) are started, and see if they seem to be taking more resources than expected (e.g. excessive RAM / CPU / HDD page faults / Page Fault Delta).

Get to know what the startup processes are via MSconfig or use...

BB speed when issue occurs is est. 2.5mbps + , this is when the HDD shoots to 100% activity.

My BB possible speed is 100mbps but this issue also occurs when I use hotspotting on my phone which is "only" 40mbps.

Get to know what the startup processes are via MSconfig or use CCleaner (recommend it for cleaning problem systems most of the time anyway). You might find that one process is causing all this.
