The base Memory address listed falls directly in a commonly used memory range for Network adaters. This may or may not be an issue as Network cards can be found at adresses of c000 to dd00, and even into the E000 area. It would probably be best to move the sound card to IRQ5 which is the legasy IRQ for sound cards. My reasoning for this is that your system probably has 2 Serial ports and posibly a modem. In Pre Plug-N-Play times, Serial ports 1 & 3 referred to as COM1 and COM3 shared IRQ 4 while Serial Ports 2 & 4 referred to as COM2 and COM4 shared IRQ3. If you have 2 serial ports, it is most likely that at least one of them is using IRQ 3 thus causing a resource conflict. If you have an internal modem, then this can further complicate the issue as it will provide it's own Serial Port, placing itself usually on IRQ 3 or 4. With the introduction of Plug-N-Play (PNP) IRQs and Base I/O Addresses and Base Memory Addresses are now up for grabs. Modems can find themselves on virtually any of the non-reserved IRQs, etc... Long disertation to basically explain that you could simply disable your second Serial port in CMOS and remove any modems to see if the issue resolves itself. Ultimately, you will want to move the Sound card to IRQ 5. This may be possible thru the CMOS setup utility burned into your BIOS or by using the driver/utility disk that came with your system/system board. I hope this helps. Thanks, Jeffrey A. McCright
