I'm having a strange problem that I can't find an answer for, or any similar posts.
I just revived a Vista Home Premium PC from the dead after simply cleaning the internals. Runs good now, nice addition.
The problem is, the router port (#3) that the "new" Vista machine is plugged into is showing activity, even after the PC is completely
I have eliminated the router and the #3 port from the equation. The port light shuts off when other PC's and PS3's are plugged into that port and they are powered down. If I plug the Vista desktop into other ports, those lights stay on indefinitely.
I have eliminated some kind of weird short ??? or something in the ethernet cable by swapping others in, same problem.
If I unplug the Vista desktop's power supply, THEN and only then does the router LAN port activity stop. As soon as I plug the PC power supply back in, the router port flashing light comes back.
Light stays flashing, even when desktop ethernet adapter disabled, and then uninstalled...
Keeps flashing thru reboot, and reinstall of ethernet adpapter driver, and then shut down as well.
Basically this Vista machine is talking thru the router at all times, no matter which router LAN port I choose, or cables I use, even after full OS and tower shut down.
I have no idea where to begin to look for a solution to this as I don't even have any idea of possible causes.
Router/LAN ports: eliminated
Ehternet adapter: eliminated ?? (not sure, but my logic sees it as eliminated)
Any help would be appreciated. Thanks ahead of time.
