Hello Q/A. Recently I bought a new RYZEN build.. Gigabyte AORUS X-470 ultra gaming,, Ryzen 3 2200g cpu/gpu,,Geil DDR4 pc 4-24000 cl16-18-18-36 Ryzen branded ram 2x8gb 16 total.. Excelvan 750 w psu,, 850 evo 250gb ssd.. everything went fine, I still win 10 64bit and all gigabyte drivers and tools,, + all updates, running fine starting to install software I use nothing that would inpare system.. this was an out of case pre setup for custom case,, everything was working well, had Norton installed.. I used for about just short of 2 weeks all siv showed good. I shut it down to go to store, for back to find it would not start !! Both cpu/dram mobo LEDs flashing back and forth, reset cmos , took ram out switched slots both paired and single on board, pulled out CPU looked fine all pins straight, cleaned reinstalled with arctic silver 5 still won't start... I've been building and repairing PC's and laptops for around 20 years.. This is the first build that for some unknown reason went bad !!! Could use some advice on this....
