1st why post in tips and tricks?
2nd if the Larian launcher error reporter popped up then it has detected a error report and will ask you to send that to Larian... that report should give better clues to what is actually going wrong
3rd as a side note are you: using mods, have some other software also running like discord or YouTube & if the system is crashing to desktop/ not blue screen then the base problem is more likely to be Ram not heat
