Hi. I just got this old computer, it wasn't working, (i posted in a previous thread) and i got it fixed, and now i have encountered a new problem. I have a usb gaming keyboard and a ps2 mouse, i tried to connect it and it light up, but when i attempted to type, it didn't do anything. i plugged in my phone charger to see if the ports were working, all of them work. I plugged the keyboard into my laptop and it works, so the keyboard is not the problem
