Thursday, then, I was able to restore my computer back to Windows Media Center Edition. As soon as that was done, I installed the video card and then transferred all of my files from the SATA drive I'd copied them onto. And as soon as that was done? Yup! Time for my fix! I played City of Heroes for an hour or so and enjoyed it immensely.
Ever since then I've been tweaking the computer to get it back to where it was before (or better). I'm currently deciding on skins & desktop colors. I'd been using "Brick" from Winders Classic (we use that at school) but wanted a change. Before then, I had a Seventh Doctor color scheme (lots of red & yellow like the logo). But now I'm going with black/white/gray. I have a few skins for QCD that work with it (one even has purple on it - yay!) Now to find something for Trillian that does the same.
(Hmmm, you know, I really like tweaking my computer. I'm glad I've now got this restore disk so that I can do this all over again when things get unweildy. Heh.)
