    Letting it run overnight is the minimum (unless you see errors befor). And
    even if no errors are reported after many hours, that would be no proof of
    absence of hardware problems (unfortunately). memtest86 does not find all RAM
    defects (but most).

    It doesn't even have to be RAM (RAM is only the prime suspect). It could be
    CPU, cache memory, chipset, IDE bus, etc.

    Having said all that: it doesn't have to be faulty hardware.

    You may want to "play"with the various ACPI kernel parameters such as
    "pci=acpi" or "acpi=oldboot". See

    Go for the default or safe settings there too (after making a note of the
    current settings).
