Issues with my ASUS ROG Maximus VI Formula

Hey everyone! It’s been a little while, but I’m back because I’ve run into a bit of a weird hiccup with my motherboard. So, here’s the deal: whenever I try to mess around with overclocking settings in the BIOS—specifically when I switch from "AUTO" over to "MANUAL"—the whole thing just completely freezes up on me. Like, total system lockdown. You can't click anything or change a single setting until you force a hard reset. And even then, you're in a race against time to switch everything back to "AUTO" before it hangs again. If you aren't fast enough, it just loops right back into that frozen state. The funny thing is, if I leave everything on "AUTO," it works perfectly fine! Everything feels totally stable. Up until now, I’ve just been tweaking minor stuff like VT settings and other little things, but this headache only kicks in the second I try to push the OC.
Any bright ideas on what might be causing this? Does anyone have a clue or some advice to help me get past this wall?

Here’s the breakdown of my current rig: Intel Pentium G3258, ASUS ROG Maximus VI Formula, 4x4 GB Kingston Beast 2400 MHz, NVIDIA GeForce GTX 970, Corsair RM650x, and a Cooler Master MasterLiquid 240 Pro... Before I upgraded to this, I was running an i5-4590 non-K, so I never really had any reason to dive into overclocking, which is why I'm hitting this roadblock for the first time now. 😵 🤦 🙂 🙂 🙂 🙂 🙂 🙂

Check if there's a newer BIOS version out and give that a shot.

You should also try performing a CMOS reset.
