    Hi, I have same problem, Vista not using both cpu's,
    I have a D490 Intel Duel core, both are listed in device manager but
    if I click task manager and view performance, there is only one graph
    for CPU and I cannot change it to two
    Yet when I reinstalled XP Pro onto other HD last weekend and ran it,
    sure enough there was two graphs for cpu's
    Re your instructions above?
    What DVD?
    Vista Ultimate 64bit is what I have.
    I tried that
    Found ACPI x64 based PC, update drive, chose let me choose and browse
    my PC, but nothing was found.

    Did anyone fix this problem?

    if so, please post reply or email me at

    Thanks

    Have you gone into task manager performance view cpu history and selected
    one graph per cpu?

    Is your MOBO BIOS up to date?
