My iPhone is not syncing and iTunes is going wack. Can anyone explain what's happening?

Question

I guess this could constitute mainly as an iTunes problem, but there is disconnect with my IPhone 5. I have just recently added new songs to my iTunes and when I plugged my iPhone in, it didn't sync. At first I really didn’t care much about it. It usually does the same thing to my younger sister’s iPod touch. I assumed that all I’d have to do is go to my song menu and check the artists and songs I wanted to add. After doing this, I clicked apply and then sync and still the music didn’t download. Again, I didn’t worry much about it (and this could be my mistake) and I tried another solution that helped me with my old iPhone. I just checked off of music as a whole, clicked apply, synced, and then waited for iTunes to tell me the sync was over. This was unsuccessful. On iTunes, under ‘On this iPhone’ it said I had no music, however my iPhone still had all of my songs and playlists. This confused me so I took it a step further and caused more damage. I rechecked music (this time clicking add entire music library as opposed to only checked items), applied the changes, plugged my iPhone back in, and synced again. My iPhones library did not change. The number of songs I had remained the same. However, this time on the computer, iTunes told me I only had three songs under ‘On this iPhone’ but the capacity bar below told me a completely different number of songs than the ‘On this iPhone’ section and the number of song read on my iPhone. At this point I gave up meddling with everything and ejected my iPhone. I don’t want to delete and re-upload iTunes to my computer unless I absolutely have to (because I will lose all of my purchased music, apps, books, etc.). Does anyone know what’s wrong with my devices? Is there an easy fix, and if I have to delete and reload iTunes is there a way to do it without losing all of my stuff? I’m desperate for help, I don’t want to mess with it any more unless I’m absolutely sure the next time I plug my phone in it won’t experience and ultimate malfunction. Anyone with a solution is greatly appreciated.

Hey DaddyPaycheck and Japamac,
Thanks both for your replies.
+You are a tenacious one, that's for sure! :-)+
I don't know if that's a good thing in this case.....;)
I do agree with the statement that it cannot handle dual processors. I swapped the the "original" working CPU with the "original" one I thought was giving me problems. It is now running (although showing as single) with the CPU I thought was bad. Both sets, original and untested, will work together and register as dual, but will be unreliable and randomly freeze.
+The defining bit of data would be if you could determine that one socket or the other is continually working, or if one is sporadic (thus explaining the occurrence of the pair working).+
I'm having trouble narrowing down that part. I can swap them back and forth and get the same result-so both sockets seem to be working. But like I said when both pairs are couple together, it shows as dual, and it works for a certain amount of time. So I know they are working to a certain degree. But when they're mixed, only one (don't know which one) is being seen.
Yes, I've run thermal calibration and everything goes fine. Even with the diagnostic disc, when the CPUs are mixed, hardware specs show one CPU. But when the original pairs are coupled, it will show both.
This is like a splinter that I can't get out. It runs great as one CPU, and I could let it go like that, but knowing that it could (and should) be dual is driving me nuts.
Is there anything either of you can think of that I can try?
