Hi, I have asus h110m-cs mobo just got warranty replaced of it and put 8gb ddr4 2133mhz ram and after pwr on, it keeps on turning off and on,off and on and so on. After turning pwr on without ram, this doesn't happen. So is this a ram issue or of mobo's. Pls help me out. Also can i again replace it? Coz it is in a warranty period. Thnx
