    The CPU is not getting warm.

    It sounds like it's beyond repair then. If it's run too long with bad
    caps it will damage other parts on the motherboard. Unless it's
    something obvious like an overheated resistor, there's no practical
    way to fix it.

    The first thing to check is that the capacitor replacement was done
    properly -- polarities were honored, no solder bridges were created
    where they didn't belong, the board wasn't shorted when it was put
    back in the case, etc.

    Then debug as if it were a new motherboard. Start with nothing more
    than is necessary installed (e.g. just a video card and some memory).

    Since it was out of the case, something else may have been disturbed.

    There's still hope, check the voltage regulator sections, if you look up a
    datasheet of the regulator chip you should be able to find a reference
    schematic which will likely be very close to what's on the board. Not really
    cost effective when you factor in time but if you like fixing things it
    could be fun.
