godlives,
Has this only started happening since you formatted the player?
Does your player run as normal when plugged into your PC?
If you have a backup of your firmware try reloading it to your player.
If you do not have a backup download s1fwx
HERE and extract your firmware runthe repair.bat in the s1fwx folder and then load it back to your player.
You can find instructions on how to do this in the Knowledge Base
