so my graphics is Intel® HD Graphics is that bad?

my fps is ok with settings on low and no shadows etc. but my computer crashes all the time when im playing the game. it happens like every 5-10 minutes, sometimes i can play for up to an hour but its still crippling. i dont know why this happens but i think it has to do with something overheating and i was wondering if applying the stuff in this guide will help with my problem too.
