have you ever used those headphones on the system before? i would hate to think that the people that made your pc jacked in your front audio ports into the wrong pins on the motherboard. if you get it to boot up try another pair of headphones on the pc. BSOD like that usually points to faulty ram though.
the only other thing i could think of is if you are plugging your headohones into an addin sound card behind you pc and the card is slack or not correctly placed into the pci slot. that little movement could short circuit pins in the pci slot.
