Hello I have been having issues with my go gear muse 8GB since july last year but didnt know who to talk to. its model is SA3MUS08S/02

it hangs indescriminately. recently it has just packed up. it is not recognised by my laptop as its power source. it sometimes comes on and it just stays on the philips welcome screen. it does not respond to the power button.

right now, i dont even know its working any more as its not charging.

i seriously need help
