Sound Card/Graphics Card Problem

I have a problem with shared IRQs. I have a Jaton i740AGP video card, and a Soundblaster PCI128 Sound card. When I boot to Windows 2000, it locks up trying to load the sound driver because it insists on sharing an IRQ between the sound card and video card. I tried disabling the assign IRQ to VGA in the BIOS, and it still hangs. I tried locking out that IRQ, and it just assigns both to a different IRQ. Is there any way to tell Windows NOT to allow ANY shared IRQs?

I'm not sure if this will help but have you tried taking out the sc and then booting up,shutting down reinstalling sc in differnt slot this may help.
i read somewhere that the slot next to the agp port is the same IRQ and 3 and 5 are the same(not sure of this)as each other,i have a simalar prob but mines with the network card and SC, i shuffled the cards around for a while until there was no conflict that i can tell.
hope it helps a little.

This kind of helped. I ended up just changing motherboards in the end. When I shuffled slots, I ended up with further problems.

First I would try switching cards around in different PCI slots. Then I'd look for a jumper on one of the cards to see if there was a manual IRQ setting on the card itself. If you set this you might need to manually configure the IRQ in device manager to the new IRQ you just set on the card. I'd also make sure I have video first and then get the sound going...Don't do both at the same time.

Good Luck

There are no jumpers, so that won't work. As for the PCI slot, I'll give that one a shot.

I had a similar problem on a PC I built. I finally went into the BIOS and disabled the PCI slots I wasn't using and assigning a static IRQ to the remaining ones. You might have to play around a little to see which ones are usable by your soundcard, but doing this in the IRQ section of your bios has a good chance of fixing the problem.

Since they're PNP, I can't disable the IRQ. It just assigns BOTH to a different IRQ, as I said in the question.
