  1. I haven’t been able to confirm one way or the other that the Vostro 400 mobo G33M03 supports a 64bit OS. Can you please help me here? Thanks

  2. I have installed a 64bit version of windows 7 on a vostro 400 G33M03, Q9550.
    Currently attempting to install windows 10 64 but stalls at the first splash display.
    It moves on with the 3w bit version with no problems.. but am not interested in 32 bit OS installs.
    Any idea how to move forward on a successful setup?

    1. There are some issues with Windows 10 Version 1803/1809 that have been addressed. I had an issue with the Realtek Audio on my Latitude 7350 causing it to freeze on the first boot. It has been resolved in Windows 10 Insider Preview Build 18343. 18343 needs updated to 18453 before installation of drivers to prevent a freeze. I know nVidia cards have also been problematic with Windows 10, does your system have one?

      In any case can you try Windows 10 Version 1903 Insider Preview to see if you get stuck on the same screen?

      1. After a bit more digging around there seems to be a problem with the G33M03 motherboard that does not support CompareExchange128, a key component or requirement of Windows 10/8.1 64bit the 32 bit versions dont require that instruction set so it will work but at this age 32 bit os will no longer be supported.. what a bummer! I appreciate the time you took to reply!

        And for anyone else, it may be time for a newer PC..
