IRQ conflict involving sound card. Software issue or bad hardware?
Posted on 2004-10-22
I recently built a new computer and am having problems that I have narrowed down to "something" involving my Sound Blaster Audigy 2 ZS. When my sound card is installed and enabled I get random BSOD and have to reboot. If I uninstall my sound card (or even just disable it in Device Manager) then I haven't noticed a problem. The BSOD would give me these kinds of errors:
***STOP: 0x000000D1 (0xF7020DD2, 0x00000005, 0x00000008, 0xF7020DD2)
However it would list any specific driver that caused the crash. I only have two PCI components, my sound card and my wireless network adapter, so I went into Device Manager and looked at my IRQ settings. I noticed immediately that IRQ 16 was being used by my video card, my sound card, and my scsi driver. I assumed this was not good so I went ahead and moved my cards to different PCI slots. Now I still get the random BSOD, but the stop message is now IRQ_NOT_LESS_OR EQUAL (no DRIVER in front, not sure if this is important or not) and it also lists different drivers (seems random) like psched.sys, ctaud2k.sys, and hap16v2k.sys. I searched the web and found that all of these drivers are related to my sound card.
I have Windows XP with sp2 and all the updates, and I double checked to make sure that all my drivers and my motherboard bios are all up to date. I also put my sound card in a friends computer and it ran stable for over an hour, so I don't think my sound card is physically defective. So right now I am at a wall because I don't know if this is just some stupid Windows IRQ issue or possibly my motherboard (or something) is physically defective. Any help in figuring out what the actual problem is and a solution would be greatly appreciated.
Almost forgot my system specs (doh)
