I only installed the files from my recovery cd, did a fresh install couple of months ago and installed latest AMD from Windows update, ended up with blinking black screen
AMD 7650 card and Intel
I got tired of using cds that didnt work so i grabbed a 8.1 iso and installed right away.
Otherwise i had to sit and watch the cd hardly work an finally end up with 8.0
This laptop came with 8.0 and also bought a license for my old win7 laptop
