I recently overclocked my CPU too much, and now my PC won't power on. I know I need to reset the BIOS, but I can't find the two pins on my ASRock 320M motherboard. I'm using a Ryzen 5 2600, and the problem started right after I was prompted to restart by Ryzen Master. This is my first time attempting overclocking, so I could really use some guidance.

Check the bottom left of your motherboard; there are three pins there that you might need. And for future reference, always consult the manual before making changes. Here’s a handy link to your ASRock A320M manual, which you can use to get detailed instructions: [ASRock Manual](https://download.asrock.com/Manual/A320M.pdf).
If you can’t access the BIOS, here’s how to clear the CMOS: First, turn off your PC and unplug it. Then, locate the CR2032 battery on the motherboard and gently remove it. After that, hold down the power button for about 15-30 seconds to clear any leftover power. If your motherboard has a jumper for clearing the CMOS, like "CLRMOS" or "Jbat," you might short those pins with a screwdriver for 5-10 seconds as well. Finally, put the battery back in, plug your PC in, and see if it boots up!
It sounds like your motherboard might not have a BIOS reset button, but you can reset the BIOS by using a jumper. Check your motherboard manual to find the right jumper. Alternatively, you could unplug the PC and remove the CMOS battery for a bit to clear the settings and then put it back in. Just be careful with overclocking; many AMD CPUs come pretty much maxed out, so simple tweaks like setting PBO to auto and enabling XMP/EXPO is usually enough for most setups.
