So here's my problem. Sometimes when I'm using the computer the peripherals I have plugged into any USB 2.0 slots freeze up and the ports seem to not work with anything. The USB 3.0 slots work fine even when the USB 2.0 don't, and the mouse and keyboard work fine in the 3.0 slots, so it's not those. Also I should mention that the front case USB 2.0 slots that are connected to the motherboard on the boards usb inputs work fine when the other 2.0 slots aren't working. Also under device manager there aren't any problems being shown with anything. Does anybody have any idea what's going on here?
