CMOS checksum error. Can't use my keyboard.

[marc9603]

I'm having a CMOS checksum error. And I can't use my keyboard. It's on a gigabyte GA-H61M-S2PV. I took out my CMOS battery. https://imgur.com/gallery/O7Byjp8. This is a image of what my screen says. I really need help, thanks.

usb keyboard? you may need a PS/2 keyboard (purple round plug) to access the defaulted BIOS as the USB support may not be enabled.

a ps/2 keyboard cannot be connected while the system is on. turn off, connect keyboard, turn on
