Does it lock up only when running X, or just whenever? If only when
running X, have you tried swapping video cards?

Sometimes a memory swap doesn't rule out all memory-related issues
(e.g., dust in the DIMM slot). You might try memtest86:

Power and heat issues are much tougher to track down, esp. if the
problem arises from motherboard circuitry...
