Why does my PC turn on and off multiple times before eventually booting to bios on startup?

This just started happening about two months ago. Just before this, one of my RAM sticks died and I replaced it with one from a different company. Both RAM sticks that I have are DDR4 and 8gb but one is a gskill trident z and the other is a gskill ripjaw. Does having two different sticks of RAM cause my computer to constantly post to BIOS and the on-and-off power cycle on boot up?

It can be, depends on the specs for each RAM stick. Generally, you'd clear CMOS and let the stick with the looser timings train, then tweak as necessary. The on off power cycle sounds like memory training, which shouldn't be occurring every time. It sounds like you're in some fail safe settings with MRC disabled so it's training every single time. Load your defaults, load XMP. See if the problem resolves, then test for stability.

Depends on the board, should be on the Tweaker tab. ASUS calls the menu AI Tweaker. Gigabyte calls it MIT. Asrock calls it OC Tweaker. MSI just calls is OC. Sounds like you're already in that menu if you found the MRC setting. Should be in the parent menu for that. Extreme Memory Profile.

@PowerSpec_MikeW Thank you for your help with this. In BIOS I am able to find MRC which was set to auto, I changed that to enabled but I am having trouble finding where to load the XMP. Also, does clearing the CMOS mean removing it from the motherboard and replacing it? I am also not sure what training the stick with looser trimmings means. I'm not too knowledgeable about this stuff so any help is much appreciated!

@PowerSpec_MikeW Thank you so much. It is back in working order!
