You may recognize that your system gets slower and slower when playing and working a lot with your pc. That's cause ur RAM is full of remaining progress pieces you do not need any more.
So create a new text file on your desktop and call it .. uhm.. "RAMcleaner" or something...
Type
FreeMem=Space(64000000) in this file and save it as RAMcleaner.vbs [ You may choose the "All Files" option when u save it ]
Run the file and your RAM is cleaned Of course you can edit the code in the file for a greater "cleaning-progress".
