Hi there, this is my first post here. A week ago I got the blue screen, I didnt know exactly the cause so I reinstalled windows and recovered my system with a backup i had on an external hard drive. Well, apparently my laptop was ok, but since yesterday I have windows crashes, my laptop reboots when Im uploading music to the cloud with itunes match, it happened twice. I ran de SF diagnostic tool, please I really need your help, Im a novice user and dont know what to do. Tanks in advance.
