Can someone tell me how to troubleshoot an issue I'm having with my NIC?  The card may be completely dead, but I'm not yet convinced of that.  

Here's the issue:  I have a Dell Studio 1737 Laptop.  The network card is not responding to any Ethernet cable that I plug in.  I've tried several different cables, 3 different routers, 1 hub.  Nothing.  No lights when I plug the cable in.  The device manager says the device is working properly, and I've uninstalled the NIC and Windows automatically re-installs it.  No luck.

Ordinarily I would think that the NIC was dead, but I had this problem before, and then suddenly after a reboot everything started working fine.  In both cases this trouble started after I switched from one router to another.  Yesterday, I was able to have some success with plugging my computer into one router, but then I would get nothing when plugging it into another.  Then it started working again, and now it's dead again.  

Does anybody have any idea as to whether there is anything else I can do?  As this is a laptop, I believe the NIC is integrated into the motherboard and cannot be replaced.  Perhaps I'm wrong?

Any help is appreciated.
