My philips go gear SA60XX 8GB player is frozen and when i turn it on, the Go Gear logo comes up but it won't go any further

You can find description about how to repair your player using this link:

If the PC doesn't recognize the device try recovery mode:

Player Recovery

Sometimes, problems still remain even after you reset the player. You need to use the Repair function in the software. Just follow the steps below:

Important: Content stored in the player will be erased after player recovery. We strongly recommend you back up your data before you perform this function.

1. Press and hold the volume plus button (VOL+) and then connect your player to your PC until the Philips Device Manager acknowledges your player and enters the recovery mode.
2. Release the volume-plus button (VOL+) button and then Click on Repair to start the recovery process.
3. Follow the information on the PC screen to disconnect your player when recovery is complete.

I hope this helps you.
Thanks.
