Hmmm??  A page fault is not a "crash".

The things I usually suspect first are memory, power supply and cooling.  MemTest86  http://www.memtest.org/  is a good exerciser / diagnostic for memory and the related chips & buses.  Download the iso, burn it, boot it, run it.  The other stuff I don't have any easy suggestions for, but memtest is a good start.
