I have Windows 7 Ultimate, 64 bit with 6 GB of Ram and SSD. After restarting the comp, the memory use is around 23% (of 6 GB). After working on it for a while, running browsers, spreadsheets, playing a game the memory use just pretty high (with just a few browsers open and Football Manager around 80%). However, the problem begins when I close all the programs, essentially going to fresh, post restart state. In this idle state, the memory use if just over 60%. This obviously seems wrong. This is over 60% use of physical memory. What is the issue here, memory leak or something else. Occasionally, when I have a bunch of things opened, the computer will hang because the memory use is at the peak.
