i need help my computer keeps randomly turning off when playing games this all started when i installed an r9 290 it started black screen frequently and i was using the gpu in the apu i was using which was fine but when i started switching to my new graphics card the r9 290 it started and i sent it back and then got a r9 280x instead it done the same thing so i sent it off to my computer shop where they got rid of a lot of versus and reinstall the infected files after having it back it was much better but after about 2 days it started again but at a much lower frequency at games like dayz standalone planet side 2 batman arkum origins battlefield 4 and some others and when it happens there no windows errors messages but it usually happens after a few hours of gaming 2-5 hour i would say.
it only happens when gaming and not in anywhere else
i know its not:
my power supply because its a 750w moddlar evo labs cranios and check power rates fine.
my cpu runs 20-30c at idle when in games it dose 50-65c in games
my gpu runs 40-50c idle when in games it dose 60-70c
i keep my computer clean of versus and clean it regular with advance system care
