I just got this computer, (with Windows 8.1) and the 60gb internal drive is filling at an alarming rate. When I first booted the computer, it showed only 20gbs of space, even though I hadn't done anything on the computer and windows only takes up 14.8gbs. I haven't visited any sketchy sites (this is my gaming computer), and I have almost nothing downloaded. I keep running CCleaners, which clears off a little bit (maybe 5-20mbs each time), and I have cleared the restore points. I even run my browsers out of my external hard drive! I cant think of anything else. It's getting quite frustrating. Please help!!!
