how can i make my usb mouse and key board work when i plug them into the front slots of my computer and not just the back usb slots? idk how this stuff works >.<
Yeah, usually there'll be a cable running from your motherboard to the inside of the front of your case where they connect to a small PCB board for your USB slots.
If they are connected, you might have to check if they're connected correctly, or it may just be that you need to install USB drivers which you can usually find at your motherboard manufacturer's website.
