greetings,

i really need a hand resetting my bios to default as my pc is stuck in a bootloop. i dont know where the jumper is on this motherboard, or where the battery is. its possible it could be behind the gpu? i have an rtx 2060 and this is my first time dealing with anything like this. i had no issues until i attempted to OC the cpu / ram. any and all help will be greatly appreciated.

It's at the bottom of the motherboard.
If you look at the left edge of metal heatsink which says Asrock on it, and trace the line down to the bottom of the motherboard, you will see two pins which say CLRCMOS1.
I would attach the photo, but work computer does not allow me that.
Alternatively, you can pop the battery out, from the motherboard. battery is held by the clip on left hand side, if you squeeze it, battery will pop out. Obviously follow every procedure explained in the manual.
Actually motherboard manual should have the position of CMOS clear pins visually shown ;)

That is usually a RAM issue, make sure you have the RAM in slots A2 and B2 or just
A2 if you only have one stick. Also make sure they are properly seated in the slot,
if they are not pushed in all the way they can cause this issue.

If that still won't get the system to POST then see if you can try some different
RAM, RAM compatibility can still be problematic with AM4.

Assuming your video card is in the x16 slot.
The battery is near the end and below the video card.
It is a round button batter.
Just take it out for a minute (unplug the computer first :-)).
