So the keyboard I have suddenly the 5 and 6 above the keys don't work anymore. Oddly enough they work in BIOS and when I login to windows, but when I wan't to use it in windows they don't work. I tried a different USB and tried to uninstall the keyboard under device management and plugging it back to to refresh the drivers, but still has the same issue. I'm wondering if there is something going on in some odd setting that caused this??
