my pc just really needs a clean install. I got it from a relative with only 256 mb ram and I have no idea what they did with it before I got it, haha. I have utorrent, chrome and LMMS running. It just takes a bit for them to start up (especially with chrome running. If not for chrome, everything runs faster) Really chrome is the only thing I have problems with, not to mention programs that need better graphics than what my integrated chip can give..
Chrome does use a lot of memory, even with no tabs open, it's got around 4-6 separate processes running.
