Hi... I have a Belkin Wireless USB network adapter. Well, every so often (seemingly at random) The Computer will act like it had been unplugged (even though it hasn't). Then an install new hardware window opens up. Usually If I unplug it and replug it, it'll come back up as normal. I'm thinking that this is a driver problem, as I've had a horrible time with the software for the adapter( I've had to un-install and re-install drivers of different versions several times) Also, something that may be of interest; If I open the hardware menu from the system manager, it somewhat prevents it from happening. BTW... It's done it twice... three times... just while I wrote this.
