Hello, i've recently been driving 80 miles round trip almost daily troubleshooting my friends PC, its a Msi x470 Mobo, ryzen 2700x, vega 64, 16Gb ddr4. Well he bought the Red devil vega 64 some months back and had it sitting around because i refused to even attempt putting it in his pc with a 500W psu, He ended up ordering a Seasonic Prime airtouch 850w Gold PSU (Imo plenty for his system, doesn't overclock or have a bunch of drives just a single HDD). Well i installed the psu and vega, all was well initially then it started going into a "standby" or low power state that require a hard reset to fix aswell as the audio got extremely quiet (Sometimes it would work find for a day then start going back into standby), reinstalled drivers numerous times no avail, i ran 2x PCIE 8 pin cables instead of daisy chain, still the same. Last night i thought it was done (minus the sound issue) however about 5 minutes from my house he messaged me and said it went into the low power state and started to smell like burnt electronics so he turned it off. I'm lost, im going back out there today with my old TT tr2 rx850 psu to see if perhaps the psu he ordered had a faulty 12v rail from the start. Anyone able to give any sort of insight as to the problems? I also thought about bringing the Vega to my place and installing it to see if i had the same issue.
