I just built a PC with my girlfriend for her, for Christmas with some pretty good hardware, she got it early as we are gonna be away over Christmas. The build went really well but now when she plays sims 4 (and yes at the moment that is sadly almost all she is using this PC for...) an hour or so in the PC sometimes freezes and if she keeps pressing any buttons or click the mouse, a blue windows screen with the sad face comes up and it says Machine_check_exemption. it has happened four times now but it has not happened once whilst playing Jedi fallen order which we have played quite a lot as well, My girlfriend says she saw an "A2" code on the motherboard when it crashed, however I cannot confirm that. It does however say "A2" every time we start the pc but the pc starts fine every time no problem.
Specs bellow and any help would be greatly appreciated.
