Could be left over garbage from a Windows update. Also, do you have hibernation turned on? If so, it could be the hiberfil.sys file.

It sounds like you need to run CCleaner ( http://www.piriform.com/ccleaner ) to clear out all temp and cache files, and then optimize your drive ( http://thessdreview.com/ssd-guides/optimization-guides/the-ssd-optimization-guide-2/ ) with emphasis on turning off hibernation, moving your paging file elsewhere (to a HDD), and shutting off system restore or at a minimum deleting old restore points.

Then depending on your drive do a manual TRIM (like Intel, Samsung, etc that have programs for their drives) or just leave the computer on so that TRIM has time to work, unless of course you have a SandForce controller other than Intel with 5.x firmware that has broken TRIM.

If you had an update it could be that a restore point was created. Your hibernation file could be large, but in which case you can delete it by typing "powercfg /h off". Shadow copy storage filling up? Bloated $TOPS file? Fixes for the last two are at http://nerdsknowbest.blogspot.com/2013/01/phantom-space-used-in-windows-7-windows.html
