I have a Lenovo Yoga IdeaPad. Recently I have had error messages saying my computer is "low on memory" and that I need to shut everything down and restart it. It especially gets bad if I am trying to stream something on youtube, or if I am reading Manga online. My shockwave has been "crashing" and there have been a few times now where my entire internet browser has crashed. I am using Google Chrome. There is no sign of a virus, I have run multiple scans. Anyone has any idea on what is going on with my computer? I have only had it for about 2 years now.
