Electrical Problem???
 

On my way to work today, all of the interior lights and the flashers (hazards) started blinking in my 2000 Boxster S. The car made it the remaining couple miles no problem, but when I turned off the car, I couldn't get the car started again. Any ideas???

Sounds like either the alternator died and the battery followed or the battery just died. Get a new battery if that one is 3 too 5 years old. Or try charging the old one. start the car and check what your alternator is putting out with high beams, a/c and all on. When the voltage drops to a certain level the ECU and dash goes bonkers. I do not think it is to serious.
