Issue after resetting

Hi,

I have encounter a strange issue on my new sansa clip zip.

After a “Fat error message” I have performed a format (like recommended in an other topic).

Actually my Sansa clip zip show me a blue screen and now I am unable to perform anything (update or format).

Can you help me ?

Regards.

Hi,

Hold power for 30 seconds 

Thank you for your answer, I have tried to press the power for 30 sec, no more blue screen but no more screen.

When I plugged it to my computer windows is unable to detect it
