XP Pro Stop Error

I am getting a Windows Stop error before reaching the desktop on my laptop. Then the computer reboots – this seems to have something to do with a driver (not really sure as the stop error does not stay on the screen long enough to get the information). The error only occured at home where I have wireless DSL. I disconnected the wireless and direct connect with ethernet and the error has reappeared only once but I am concerned next time it occurs I will not be able to correct. Any suggestions —-
