I decided to install XP again in Standard PC mode.....it is now running absolutely as it should: Pulsar 2, SRB and UAD-1 all working hand in hand. [I found ,after all that ACPI mode was not the Holy Grail, and is much more prone to glitching/crackling etc....bit disappointing because of course, you can't use Hyperthreading in Std PC mode, but as Scope is the heart of my system, I have to prioritize it.]
The MOST IMPORTANT factor seems to have been updating the Chipset Inf.[EDIT: I must add, IF you need to do this,it MUST be done before installing any hardware drivers....best done immediately after a fresh OS install, and with no peripherals attached too, in order to prevent Windows from automatically trying to install hardware in the middle of the BIOS update]
I couldn't believe it when I saw this was not installed (by loading the Mobo CD that came in the box)....you see I bought this thing from a 'reputable' music shop (naming no names erDIG er ITAL Village or something), believing it to be totally set up for music, and I have gone through sooo many tweaks to get the damn thing settled....Bloody shops eh? (I knew something wasn't right when I told the guy I was into Creamware stuff, and he said 'Oh I don't like them...over-complicated & unstable').
Anyway, I've finally come out the other side, with what I set out to get in the first place...the Dog's bo**ox...

A few key steps were:
Disabling Graphics Acceleration and write-combining;
Setting PCI latency to 64;
Various tweaks found at pcaudiolabs.com ;
Disabling unneeded services;
Ignoring bozo shop attendants when they slag Creamware off,
And MOST IMPORTANTLY, Being a member of the coolest forum on earth...that being the mighty Z.
Thanks to all you guys, this place sure is a wealth of knowledge.
