I rcently got a new computer for christmas and with it I have a 250GB Hard Drive (233GB to be exact) and after installing all my programs, games, documents etc. I was left with around 150GB of space remaining. Then yesterday I left my pc for an hour or so came back and there was a bubble from the tollbar saying very low amount of space left on the c drive. Turns out I had 0 space remaining?! Now whenever I check it varies, so far from 2gb to 6gb but where has that 150gb of space gone?
