My Xps 420 runs off a wireless card because its downstairs (little usb belkin pos). Anyway, whenever I plug it in, I get this error message about shutting down in one minute. However, when I take the card out, I can start the computer and play solitaire for hours. I looked it up on the Vista forums and what they claimed it would be (some brazilian hot wax thing) was not to be as I never downloaded the file. AVG and spybot all come up negative. Help?
