My pc will run then turn off

Did you get your RAM replaced? I've had this issue with my board (Gigabyte Z790 Gaming X AX) where last time after only a week of normal use, my PC would start switching between CPU and DRAM lights and the RAM stick in slot B2 was dead for the 5th time. Try getting your RAM replaced and put them in slots A1 and B1 as B2 apparently causes regular failures
