Sometimes, immediately upon power up, my Desktop display shows a bubble error message down by the Notification Area. The message: Local Area Connection - A network cable is unplugged. (Not so) The bubble fades away after a few seconds.
I suspect this may be related to a complete purge and reinstall of my OS last July. I picked up a nasty virus which I could not clear. I tried to work with Dell (in India) for more than two weeks with no success (no surprise to me). Finally took my PC to my local fix it shop.
They cleaned out the bug, but told me that my Dell built-in Network Interface card was bad, so they installed a different interface card.
They left the Dell card installed, but with no cable connecting that card to my external modem. The new interface card now connects to my modem.
Can anyone suggest how to eliminate these occasional error messages upon startup?
