memory voltage 2.1
Make sure that the memory timings are not set to 4-4-4-x but that they are set to the defaults values (5-5-5-x).  Also ensure, that the memory clock speed is not set to anything higher than 400 MHz (=DDR2-800).  The voltage at these settings should not need to exceed 1.95V.  So please lower it accordingly.  In case the freezes still occure, please run memtest86+ to check your memory for errors.

msi dual core center
Please get rid of that tool for all further tests.  Uninstall it completely from your system as it is known to cause crashes and freezes on its own terms when running.
