Vengance 2100 - Problem turning on?

Hi iv'e had my vengance 2100 for a year and 3 month now. it's been working great! until now?



I woke up this morning then i turned on my computer and my headset but it just wouldn't.



The blue light just appears for 3 seconds and after the charge light 3 second (if The charger is pluggen in) if not just the blue light



i tried charging it to 100% but it's still the same...



Anybody know's what to do? :)
