But maybe it's not the OS. Maybe check your memory. Get rid of the clutter. BUT if you do decide to install some other OS back everything up. I lost ALL my stuff on my other laptop because something went wrong when I installed Linux. IT was supposed to run alongside Windows, but instead wiped my hard drive. I had work that I had spent hours, days, weeks on just gone. Of course that's my fault because I failed to take the correct precautions by backing it all up.
