From your description it's not clear what the problem is. After you see that "streaking line" and the black background screen, do you reach the logon screen - or - is your PC hanging ? If so, restart in Safe Mode. Can you reach the desktop there ?

BTW, by "hotfix 2" do you mean SP2 (service pack 2) ? Anyway, what you see in the first screen on boot is called BIOS POST and that's independent of the installed operating system

Good Luck,
