Computer locks up when watching a video

My Mac mini goes black then I get three beeps in a loop. Seems related to watching videos or playing a browser based game. Apple Store checked RAM which showed okay but maybe not securely in place. Reset and it started normally.

After running at home for a time it crashed again. After unplugged and sitting overnight, it started but with everything tinted purple. Restart gave a normal screen but went black with beeps in a loop again when attempting to watch a video.

Are you sure you have the 2012 model? I'm suspecting you might have one of the 2011 models. In that series the discreet GPU’s often failed.

If you're sure then your CPU's graphics engine has failed or the CPU's solder joints are heat fatigued (failing) we often call this cold solder joints.

Cold solder joints seems reasonable. It has seemed to be over heated lately. Looks like a new old machine in my future.
