A client has win 95 and installed a modem and sound card. The first modem didn't work, bought a new one which did work. She then installed a sound card which had problems. While re-installing the sound card the modem started having Error 602 (port already open). I checked the IRQ's and none were doubled up. I switched from com 4 to com 2 which solved the 602 error but now 630 pops up modem not turned on. I have taken out both cards and the ram - reinstalled, but am still stuck. Any ideas
