How can I activate Vista if...?

Question

Here I go. So, I got a little trojan on my other hard drive, and now vista(ultimate) won't load. I mean, it gets up to the logon screen, but then the computer restarts. Anyway, I can't get in, no matter how(not in safe mode either). So I decided to install vista again on a free partition.And I did. Now I can't activate and I dunno what to do, cause it says the key's being used by another computer. I don't think formatting the other computer will likely do anything, so here I am. Anyone got any ideas?

Answer 1

Vista activation can also be done by phone. Yes formatting the hard drive (assuming you save all the valuable info) will do good.

Vista records information about your computer, that's how it tries to decipher if you are reinstalling it on the same computer, or another one.

Formatting the original hard drive, then reinstalling it will tell it that it is the same computer and you shouldn't have any problems.
