I've been trying to get the wireless broadband to work on a laptop in my house and after having a little fiddle i turned off the laptop, next time i turned it on it wouldn't load, it sometimes goes to the microsoft windows xp loads screen and the blue bar will just load (scroll) on and on. or sometimes it says there was a problem and gives me the option to start normally, start in the last known good condition or any of 3 safe modes, none of these option load. can anyone help?
