So im very new to this. Built my own pc last week and it keeps restarting on me whenever i play games (modern warfare). At first i thought it was the game because of all the server problems its facing but i recently noticed that whenver it restarts, my mobo red light will turn on in this sequence. DRAM, VGA then boot. these are my specs. Everything is in warranty.
Aorus B450M pro wifi
Ryzen 3600
Crucial Ballistix 16GB DDR4 3200MHz CL16 Non-ECC Dimm Desktop Gaming Memory
Gigabyte RX 5700XT Gaming OC
Seasonic 750W Focus Gold Plus
Everything is brand new except the psu. Thats still on warranty for another 6 years.
