Rover owners: Help Needed! Car Wont Start

My car seems to have died! Was fine until I got home then the lights went really dim and the radio switched on and off. Then the ABS and handbrake warning lights came on (see pic) then the dials stopped working altogether including no reading on the ODO. now the car wont start and just beeps, as if the battery is flat (its not) I have tried to jump the car it still wont start, see vid for idea of what im talking about.
