I just reinstalled windows and my computer now can not detect my internal 3com PCI modem. In the device maneger it states there is an IRQ conflict which forces me to either disable the Printer port (LPT1 & COM) or my sound card as to free up resorces of one or the other. Also in the device maniger It is unable to detect a PCI communication device because of missing drivers, I think it is possible that this unidentified device my modem but I am unsure. I have not added or removed any hardware sence the reinstall, so I dont know how this IRQ conflict came about in any event does any one know how to resolve such an issue.
