It looks like the ntkrnlpx.exe is the problem, a quick google search showsthat it is some sort of program to remove the ram limmits on windows, and should probably be removed.

Next I notice that your version of windows is missing service pack 1 please update to service pack one, i contains a number of security and stability fixes:
