i uninstalled my webcam central from my dell 1737 with vista, i did this as it never worked. i go to the site on dell that says my dell downloads, i clicked register my system but it goes no further. it says examining your compter please wait.

I have an Inspiron 7520 that originally came without a msata card. I've changed the daugtherboard and installed a 128Gb Crucial mSata Card. My idea is to use the msata as an individual Unit with SO and common applications and the Original 750gb HDD for the rest of the data (Not an Hybrid disk).
