Hello dear tech people i have a question i bought a Ryzen CPU&MB back in march and i had to flash it (which i did[even if i was totally scared from all drawbacks that i heard that can happen]) because i had very big stability problems after the flashing since then i had 3 RX 480 in tri-fire and there worked fine no failed boots or that only temps where the problem and my problem is since i´ve sold them (mining hype) and bought 2x RX 580 XFX 8GB Dual CF (both watercooled [AIO]) in this summer beginning of september they work fine temps are fine and performance is good though i´ve noticed that my primary 580 sometimes or rare, happens to be stopped detected when i boot up my PC. And i see a red LED lighting up (near by my ATX-24PIN) on my motherboard that tells me that my GPU is either not detected or damaged and i took it out of my PC and checked if there are some scratches or something broken but it looked fine. Then i put my 2nd 580 on the primary PCIe it worked without any problems and the 1st 580 i´ve put it on my 2nd PCIe slot and there was the same thing too that it doesn´t being detected after some start ups, then i tried it again with my 1st 580 in the 1 PCIe slot and after 4-8 failed boot it booted up and worked though after 1 1/2 months it started having stability issues during GPU intense application or games (yes i´ve had it OCed and after some crashes i just let it on the default profile to prevent any serious damages) when i´m playing GPU intense games like DOOM, Crysis 1-3, etc. at some point after 1-3 hours my monitors they just turn off and my PC shuts down but not entirely the fans are still moving then i have to restart it and know that i need to boot it up multiple times like 3-8 times to make it run again and then everything is normal again i dont have any graphic issues or something flickering this happens like it is a trigger there are days or weeks when this doesnt happen that my PC just shuts down when i´m running some intense GPU application (except failed boot that happen everytime i boot it up which is annyong sometimes[BUT it only started to happen those failed boot ups since i´ve got the 580 before them i had 3 RX 480 which i sold during the mining hype and with the 480s i didnt have any problems at all when it comes to boot but triple crossfire was mostly more like hell than heaven reason lack of support and scaling.) And i thought that my 1st 580 something is wrong with it but after a video from a tech-tuber (jayztwocents) he had the same issue as i have he had 2 the same titan Xp´s the one titan booted up without any problem but the other one had to be booted up like multiple times and he had 2 rigs right next to each other both of the titans worked fine on the intel system but on the ryzen system that one titan had some issue to booted up and after that i had another idea i had my old FX-8350 rig and i´ve tested it out and found it that both of my 580 worked wonderful without any problems. Can it be that my motherboard needs to be flashed again? Which i´m scared of flashing because of all the negative things that i heard what can happen. On the MSI website there are a lot of new bios version which a lot of them are for system stability improvmend and memory stabilitys and here is my 2nd problem can i flash a motherboard again and do i have to flash all those updates or just the newest one ?
If someone can help me i´ll be very happy about it.
sry for bad english
