Same here I have a Dell Optiplex 3010 with Linux Mint 17 Cinnamon 64bit and it freezes, No nVidia or ITI GPU , I guess intel Integrated graphics , I notice that this happens when there is too much stuff open but its really not that much (browser with 5 Tabs in Chrome of Firefox and a remote Desktop would do it) I know this computer is capable of running many more things (core I5 , 4gb ram) should not sweat it
