Is it possible that I blew a fuse somewhere? yes it should. no there's no fuse. you'll need a multimeter, be *careful*. i suggest taking the Card out. if it's really borked you can power it with a 5V USB "charger" cable (into the 2 standard USB sockets). also, check you inserted the Card correctly: not one row along or one pin along, and make sure no contact between the two PCBs. > Apart from that, I currently can’t get the system to boot.
