I'm having pretty much any sizeable app (browsers, FB, YouTube, etc.) crash after doing very little. Loading images and vids frequently max out the clogged RAM. I can't even scan through half a day's worth of FB postings without crashing several times. I have a couple of utilities to free up RAM (which quickly gets appallingly low), but of course clearing RAM also closes open apps, so you can't really clear RAM proactively.
Any tips or suggestions?
