Long story, but today I plugged my iPhone into my pc to charge it up. Straight after plugging the phone in, there was a message displayed on screen, but by the time I noticed it, the monitor had gone blue and the pc was running some form of scan search, all that was displayed was a count down timer, after which the pc shut down and then restarted, but once the pc started up the " Compaq" screen bootup/system recovery screen has displayed, the screen goes blank, as it would on boot up, but then a cursor is displayed at the top of the screen, which then goes down a few 'lines' on the monitor, and then the pc just hangs and does nothing. I have tried to get to safe mode, but Im guessing as the pc isnt booting up, I wont be able to get as far as safe mode. Prior to this the pc ran fine, the only thing that I have added to it reccently is a usb wireless adapter, and I left the run disc for this in the cd player on the machine, so would this have anything to do with the problem? I have no XP disc or recovery floppy disc, so I dont know what to do. Can anyone help me please?
