My PC has only 12.2 of 19.1 GB of free space available. Because of this, I believe, my computer lags and is often somewhat slow. I have done everything I can to free up space (i.e., disk clean up, constantly erase cookies, defrag, always removing programs, etc.) AND my PC hardly has any music, games, or programs saved on the harddrive. Also, the other day it seemed like I had 13.0 free space and all of the sudden it is down to 12.2 and I swear I haven't added a single program. I fully do not understand how I have taken up so much space and would really like to know how to free up as much space as possible. Does anyone have any suggestions? I'd really appreciate any help. Thanks!
