|"tried 3 different keyboards. 1 wireless, 1 usb, 1 thru the mouse ports"|
You will not be able to use either a wireless or USB keyboard before the operating system has booted unless Legacy USB support was enabled in BIOS at some time in the past. Then only a wired USB device would work since wireless needs drivers that only load up with the operating system.
You do not connect a PS/2 keyboard to a "mouse port"
It connects to the appropriate PS/2 keyboard port ( Usually purple)
I've never heard of logging in to SafeMode via msconfig.
Shut down the system. Connect a PS/2 keyboard. Press power button and while it is booting tap F8 key until the boot options menu shows up. Arrow up/down to select Safe Mode then Enter.
