Hello,
Recently I put together a new PC DAW system with i7 950 @ 3.07GHz and GA-X58A-UD5 as a base. I must admit that I was surprised when I realized that changing IRQ in WIN 7 isn't so easy (if at all) as in my previous Win XP system.
Now to the description of the problem.
Win 7 have assigned VGA and my sound card to same 16 IRQ number (worst scenario). On top of that, a buch of PCI and USB controllers has been assigned to same IRQ 16. Clearly, that activities is causing much clicks and pops in Cubase 5/6. I had same problem before in old DAW:s. But then, assigned sound card to different, dedicated IRQ - solves the problem on the spot.
I was able to disable some USB controller from that shared IRQ with noticeable better results in audio performance, but unfortunately the side effect was blue screen every time I turned off or restarted PC. Maybe I haven't done it proper way?
Now I think that I have following options and I need help to realize some of them:
1. Assign dedicated IRQ number to PCI-slot sound card; BEST SOLUTION
2. Make as much as possible space on that IRQ so that PCI-slot sound card can work frealy;
3. Assign a dedicated IRQ to VGA card;
4. Re-alocate PCI-slot sound card into PCIEX1_1 slot with this adapter:

5. Replace my current GA-X58A-UD5 MOBO with some from GA-P55 line as they have 3 x PCI slots.
Just to be clear, yes I have done all necessary tweaks and optimized Win 7 for professional audio work.
I would really appreciate your help as I have a tight dead line and need to get this solved. In Win 7 system this shows:
During Win boot this shows in "PCI device listing"
