Other option to consider that will extend the life of your current hard drive:
Turn off System Restore if not used:
System Restore has always been a mess (from my experience) and, many times does not fix your reported problem. Alternatively, you can do a periodic System Image backup as an alternative method of recovery.
Run without a paging file:
Your specs indicate that you have a whopping 16GBs of RAM installed; yes? If so, you do not need a paging file and there are many that have opted to run without one. In fact, I haven't had a paging file since the old XP days and, even then, I ran without one when I upgraded to 3GBs of RAM. However, there is a slight downside to running without a paging file; in that, your crash dump initialization may fail on boot and you may not be able to capture full kernel dumps. This inconvenience has never been an issue for me personally.
