I have a problem with my strix Vega 64, Randomly under load or not under load my screen will go black with a few random thin multi colored lines going across. The sound will play for 10 or seconds after the black screen, They leds and fan keep running.
I sent the GPU back and received a new replacement and still have the same problem, I also tried my RX 480 and a friends GTX 1060 with no problems.
When i built the pc I installed a RM750x and was told by AMD that sometimes a 750 watt in not enough so I got a new RM1000i but the problem is still present.
I used two separate cords to connect to the GPU, I seen a YouTube video and it said you have to plug them into connections not close to each on the PSU, this made no sense to me but I dont know much about PSU's so i tried it.
I still have the same problem 3 or 4 times a day and don't want to throw anymore money at this if i can.
I have a large case with many fans and leds and a Noctua NH D15 cooler, I removed all Overclocks and still have the problem.
I have also done a clean install of windows 10 with all new drivers
The GPU does not get above 75c and a lot of the times its in the 50's when it crashes
any ideas or anything I can try would be greatly appreciated
