Hello, when I XMP (2.0) my DDR4 to stock mhz (3200) my PC boots up, and immediately shuts down, this does all the time, but, when I unplug the power cord from the outlet, and let it unplugged for few seconds and then plug it again, the PC starts normally. Why should I have to do this process all the time to boot up my PC? It feels like it's a problem with the bios or something.
