Well, if you use IE, have you disabled smooth scrolling.
No, I have not disabled it and don't feel I should have to.
And another thing, ACPI takes care of IRQ's. What you should check is that little nice table in the Mobo manual that states which slots share which adress lines, then reinsert the cards so the live doesnt share with any other card.
It was already in a non-shared slot.
And i cant believe Creative is that Bad.
Something specific to my configuration is the cause of this problem, otherwise I'm sure we'd see more of the same reports. I did a clean install and don't run any CPU intensive tasks in the background. I cannot believe my luck on this
