Okay so I'm in dire need of help and I'm almost sure it has something to do with my graphics cards but I'd rather be safe than sorry so first here's system specs
CPU: Intel i7-6700k
CPU Cooler: H100i V2
Motherboard: ASUS ROG Maximus VIII Hero LGA 1151
Graphics Cards: MSI R9 390 Gaming
PSU: EVGA Supernova 850 G2
Storage: Samsung 750 Evo 250GB, Western Digital 1TBHD (x2)
Memory: G.Skill 16GB (2x8) 3200MHz DDR4
Case: Corsair Air 540

Okay now I know some of that stuff is unneeded but I included them just in case. So what's been happening is strange to me, first I started the computer in UEFI mode and it was fine for a while so I walked away and came back and the screen was black, I assumed it went to sleep but if wouldn't wake up so I hard reset it. That was the day I finished building it back in October, it happened again so I turned off sleep mode to see if it was that and that was when I noticed what was really happening. I changed the bios settings all back to default and I hopped on and it seemed to be fine and then I was watching a YouTube video and the screen flickered black, the audio played for 3-4 seconds and then the audio started buzzing like it was frozen so I hard reset, updated graphics drivers, no luck. Sometimes I can play for hours and it will be completely okay, others it's been on for 30 seconds on the home screen and it goes out. If there is no audio playing no noise is made but when there is it stutters on the last noise and buzzes until I hard reset. So yeah if you need any more details but please let me know if there's anything you know to fix this. I've run MemTests and it all checks out but tonight I'm gonna try to run integrated graphics and see if it still happens. Just in the mean time let me know if I'm wasting my time thanks!
 
Solution
Is anything overclocked? Did you check for temperature issues? Clean out the case, re-seat heatsink with new thermal paste, re-seat RAM and video card?

If everything looks good, it may be a power supply issue, video card issue, RAM, Motherboard. Test RAM one stick at a time, easiest and free. Then contact EVGA and go from there, if a new PSU does not help, try the video card.
