try checking thermal paste on pro- update Bios to latest, try previous titals like bf3 etc and see if same happens , if not then your issue is with graphics card and ram. either change ram settings in bios to default and role back graphics to latest offical and work up to beta then latest.
Do this with graphics card first and let me know if yo have any issues with bf3 / titan fall or others , testing on diff graphics settings in game can also help , dont go max at start just play on Med-High. This sounds like a heat issue to me on card with latest update .
