Suggestion: set pagefile.sys to ZERO, reboot, defrag, set pagefil.sys to 12228MB min and max, reboot - should give you a single permanent monolithic pagefiile.sys

Other than that I would look for more about the freezes in Mirrors Edge as it is the more severe case of poor performance. Is there a forum related to the game?

Done No Change

In your situation, I would pursue a fix on the Mirrors Edge problems (ME support, etc) while paying close attention to HDD (SMART, etc - it might be failing) and RAM (overnight Memtest86 - it might be failing).

Good luck - keep us posted about what you learn.
