BMW 325xi Starting problem

problem with my bmw it was died on me on free way last winter. The meter go up show over heat, all light flashes. I towed it home sitting in the garage, when i try start its not starting its show all lights pop up. After i let it park there for few months i start the car no headlights, no lights on at all, like the battery drain out or something, i havent jump start the car yet...

I'm assuming can be a battery or something overheat problem? the battery was changed 1 year ago or over 1 year. Please help before i take this thing to the shop it will mean alot :)

So what was wrong with your car?

I've got the same problem. Any issues ?

Ignition switch? There can be tons of problems really
