Question Overclocked ryzen 5700 black screen afterwards

[AstraNova]

Dual channel ddr4 motherboard biostar m450, 32gb ram, m.2 drive, unsure about the battery, ryzen 5700 cpu, 1660 super GPU.

I decided to overclock my cpu it was set to auto with no number so I changed it to 45 after someone suggested it and I turned my pc back on and now it's not turning on. My motherboard has no cmos battery. It has a jcmos1 3 pin set up I took the cap off after unplugging pc, turning it off and then I think unplugged battery and then connected the pins with a screwdriver as said online. I then plugged pc back together completely and then turned it on and it didn't work. Please help!

Clear the CMOS by disconnecting from the wall and display, then removing the CMOS battery, press and hold down the power button for 30secs to drain any residual power, then replace the battery after 30mins.

You need many other adjustments beside just setting permanent multiplier because most automatic settings are disabled and have to be done manually to match frequency,
