Basically my computer will start up and run and I will load up a game and it will run beautifully and then about 30 mins in the computer black screen and buzzes really loud for about 10 seconds then goes quiet but the computer still stays running but nothing ever happens I gotta flip the switch on the back of the psu to restart the system I have tired 2 different psus and rma'd the mother board so I am really out of ideas and it's making me pretty depressed lol thanks in advance here are my system specs below
AMD FX 8350
12GB DDR3
RX 470
Corsair cx750m
Asus M5A78-L/USB-3 motherboard
And it crashes on every game I own and my temps are good never goes above 50 celcius
