the DPC issues come from GPU issues:
Please try the 14.2 Beta driver:
Ah now i'm really worried about the plug socket my PC is plugged into I had one GPU in my PC and the sound issues were present and not too bad, but then my other GPU arrived and I've added that in too and now the issues are really noticeable as you can see.
This was on the 13.12 drivers. So one thing I did was I downoaded the 14.2beta drivers yesterday before I made my post here and so those 14.2beta drivers are the ones I am already running http://i.imgur.com/85xMCVa.jpg
To give a small bit of background I have got a refund on three (!) prebuilt systems because of various bluescreen problems and PSU's dying (and poor service) but this fourth computer I build with my own two hands because I was sick of poorly build PC's from these companies but its starting to look like these plug sockets are the problem, they were not
put in by a qualified electrician and could be the entire problem with not enough wattage or power draw.
I'm think i'm going to disconnect my computer now before any damage is done and read your next reply from my laptop while I see if I can use another room in the house
A couple of examples of why I suspect the plugs, if you've ever used some of these "home plugs" before for internet http://i.imgur.com/7I8QWO0.jpg
the plug sockets in this room at the only ones where I can't get anywhere near my full speed (1mb instead of 75mb) and also If I try to charge my laptop up here I get a error onscreen that says "unrecognised AC Power, Plug in somewhere else"
