Hard lockups are generally a hardware issue. Turn off graphics
acceleration (and if you are using the nvidia binary drivers also
disable the agp support). The ram is a good place to look as well, try
running the memtest feature that is on the boot menu. I always start by
pulling all unimportant cards (that includes pulling all but one memory
stick) and all unimportant accessories and then seeing if I can
reproduce the problem. Also see if there is a way you can cause the
problem to occur regularly, like starting and stopping glxgears, or
running the bonnie++ hard disk and io tests.
Another random thought, look at the voltages displayerd in the hardware
monitor features in the bios. If anything is too far off, or the
temps/fan speeds are wrong you might be able to move towards that, low
possibility though.
