Motherboard not detecting USB devices (stuck in BIOS)

[Shane Berlinger]

Hello,
I recently bought a new PC off of eBay. It was listed as for parts and I managed to repair it by installing a cheap video card into it. It now boots to BIOS and works completely fine, except I cannot use any of the functions of the BIOS because none of the USB ports will respond to a keyboard or mouse. As far as I can tell, all other ports are functional and the motherboard itself works fine, except the USB ports don't. They keyboards and mice I have tried are as follows: a razer deathstalker wired keyboard, an older apple wired keyboard, an older dell wireless keyboard, a razer deathadder mouse, and a generic wireless mouse. I do have a driver I have not yet put into the DVD drive and let run, I don't think that would fix anything though. I'm hoping someone much more knowledgeable about these things than me could help 😛 thanks. I think I should add that this is an older keyboard that only has usb 2.0 and has older ps/2 ports, but I do not have a keyboard that will go into one of these ports. Can I get a usb adapter for this port and maybe get it to work?

What make and model in the mobo?

Maybe the USB is disabled?

It is a GeForce 6100-m-9 motherboard, according to the eBay listing it was purchased from. I can't un-disable the USB being turned off if this is the case (unless it is a physical mobo switch) as i am stuck in bios and cannot boot it up.

this is an old motherboard. Some of the older motherboards had the USB disabled by default.

So the system just boots into the BIOS, and you cannot move around in the BIOS, right?

do you have a HDD attached? Does the BIOS detect the HDD during hardware/BIOS check?

the only way to check if the USB is disable or the USB is bad would be to test with a PS2 keyboard.
