Okay, I might just have a solution for you..... First, I see you have the 12.90 dets - that's good. You need the 4.32 4-in-1's - you can get them from www.overclockersonline.com. Next, make sure your soundblaster doesn't have any cards in the slots adjacent (I would recommend putting it in the slot furthest from your AGP slot, and last and most importantly go into your bios and tell it to reserve IRQ5 for a legacy device. That should fix the problem.
