itunes broken, got new machine, how deauthorize old itunes?

Hope somebody can help...I have a Mac Mini. After a few years of trouble-free use, and lots of music in my tunes library, all of a sudden I-Tunes wouldn't open. (Also couldn't open IDVD). In the meantime, I decided to get a new IMac because it's way more powerful and I wanna run Adobe CS4, and have more space, etc...But I never resolved the Itunes problem on my Mac Mini. Now I want to deauthorize that computer's Itunes so when I set up the new IMac there won't be another computer already registered to my Ipod, downloads, etc...But how can I do this if I can't get into Itunes on the Mini? Also, if I want to sell the Mini or give it away, I definitely want to wipe all authorizations out. Can I do this merely by reinstalling the original OS Install discs? Would this repair any problems with Itunes? And would I be able to then deauthorize it on that computer?

I'm not very computer savy, but can follow directions if they're specific.

Thanks.

Here's what you need:

Thanks. So I see I can deauthorize the old computer without even having direct access to it. Great. I'll go ahead and wipe it clean now.

Thanks.

FYI... I believe you can do the batch de-authorize only once every 365 days.

Correct. Our family had to batch deauthorize 4 iTunes accounts, and you have to wait one full year, as stated above, to batch deauthorize again.

So just be careful.
