Selecting an option to use only a small box around the guide star completely rectified the issue, which I believe has something to do with the new laptops USB ports.

Absolutely right - and Terry fixed this issue to with the new firmware (he sent me a copy of the beta, which definitely fixed the issue on my new laptop). Never had the issue on the old laptop, and I continue using that same laptop (9 years old). My original Lodestar is incredibly "clean" with very few bad/hot pixels. I use 4 sec guiding and get an almost perfectly dark sky if I subtract darks.
I find MaxIM 6's guiding absolutely perfect, so not overly sure how it behaves in PHD2 these days. MaxIM uses a TINY subframe that is VERY tight around the selected star.
