Cant access BIOS with Keyboard, I think i messed up

[thansen971]

I'm building a PC for a friend of mine and when I initialy started the PC up i used my Corsair Keyboard and mouse and it worked fine. I was planning on installing windows 10 from a USB so i switched the boot order to USB first. Now when I turn the PC back on it doesnt recognize my keyboard or mouse, nor will it boot from my USB. any tips on how to either fix this or reset the BIOS?


Im using a MSI Z270 SLI Plus MoBo and i cant seem to locate the jumper on it. would my best option be buying a PS2 keyboard? would that even work? Any and all help is appreciated thanks!

The MB has the jumper, which is next to the CMOS battery, JBAT1. Also you can remove the CMOS battery too. Check the manual. https://www.msi.com/Motherboard/support/Z270-SLI-PLUS
