Let me guess, you set it to 0. That just clears out the paging file. It will revert to a default afterwards (windows control). I dont think you can or would really want to disable paging file.
Altough u have a big amount of RAm, u still need paging file, cannot totally dont want, Window by default with set back a bit if u off it. U can decrease the size of the paging file, but makesure u turn on the largesystemcache.
