iPod 160 GB Please Help! Any Ideas?

Hi, I have an iPod classic 160 gb, its about 5 or 6 years old and its just been sitting in a drawer for years because when I got this as my fourth replacement ipod, mine either melted (twice) or everytime they would send me a new one it would die on me after all i tried to do was sync the thing. I have a pc and the lastest version of itunes and all that jazz, ive dealt with tons of issues for years but this ipod is stumping me. it charges just fine and windows and itunes recognizes it, but when it comes to syncing its slows my whole computer down its almost impossible to do anything, i think it may have even come very close to corrupting both of my usb ports, it takes forever to sync and it never finishes, when it does stop the sync if comes up with 40 different error message, none of my songs are missing or corrupted, my pc is new and ive run a disk scan on it multiple times on my ipod and comes up saying nothing is wrong. i just can't bring myself to throw it away but i certainly dont want this thing to destroy the rest of my computer if it really is that bad.
