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!
