While the old ethernet port is unresponsive, the computer still recognizes it as functioning hardware that's working properly. I tried uninstalling the old port, but it wouldn't allow me, saying that the computer needs it during boot-up. So then I thought disabling the on board port would make the new card work, but it didn't. I also tried putting the new card into a different slot but got the same error. My first impulse was that there's an IRQ conflict from having both ports running, even though the on board one isn't responsive, but I have no clue how to go about finding out.
I've attached a screen shot of the device manager, showing the old port disabled and the new card with an error.
Windows XP Home Edition, version 2002, sp3
Celeron 2.20 GHz
768 MB Ram
New ethernet card:
TRENDnet TEG-PCITXR 32 bit 10/100/1000 Mbps PCI adapter
Any help would be greatly appreciated! This is so frustrating! Please let me know if more info is needed.
