Oops! meant 2TB HDD of course.

Agree with hornet re- imaging your c: drive. This is a thing I've always done, even before using SSD's.

Best program to do this, that I've found so far, is called Macrium Reflect. The free version is all a home user needs. It's very simple to use, extremely fast, and makes efficient compressed images. I've restored images with it, and it worked flawlessly.
