IPod Touch 4th Gen has no songs/incomplete songs after Syncing?

Question

So I recieved an iPod Touch for my birthday:
After syncing the music into my iPod manually, the music is shown to be in my iPod on iTunes, but when I go on my iPod and push on the Music Ap, it says there's no music. When the music did sometimes show up on my iPod it was incomplete and most of the song was cut off. I also cannot restore my iPod it becomes frozen and I have to continue it on another computer.
I can sync apps, etc on to my iPod but not music. I've looked at countless threads where people had this problem, many remained unsolved, I tried what was told where the problem was fixed (playing the music from my iPod on iTunes, then resyncing, etc), still not fixed.
On the other hand if I use my sister's computer and sync her music, it works?
My sister cannot get music off my computer on to her iPod either, so I'm pretty sure it's not my iPod.
I honestly do not want to put all my songs on to a relatives computer just to put songs on my iPod it's too much of a hassle (it works, it's just too much work), I do not want to do that everytime I want more music. I want to sync music on my computer.
Is there a solid solution to this problem?
I apologize for the complain, but I am extremely frustrated.
Things I've tried:
-Reinstalling iTunes, restoring the iPod, resyncing, replaying music on iTunes off iPod, updating iPod, updating iTunes, checking Sync Music box, manually adding music.
I also have Windows 7 if that helps.
Thanks in advance to those who can help!

Answer 1

Try resetting the iPod.
Next would be to restore from backup
Finally, restore to factoery defaults/new iPod.
