I am currently running Windows 2k on an A7V motherboard with a 1.1 GHz AMD Athlon. In addition, I am attempting to install two different PCI sound cards. However, I am encountering major IRQ conflicts. I have attempted to manually change the IRQ of one of the sound cards to 5 and 12, the only two IRQ's which appear to be available on my system. However, on IRQ 5, my comptuer hangs on startup and on IRQ 12, my computer no longer recognizes the sound card. Any advice would be greatly appreciated. Thank you in advanced.
