Yesterday I upgraded my old PC, I got a new motherboard, a new case and a new PSU. Unfortunetly my mouse and keyboard doesn’t seem to be working with it :/. At startup it says that it recognizes 2 USB devices and specifies them as keyboard and mouse. In windows however, neither works.

I’ve tried with 2 different mouses and two different keyboards that works on my other computer. And I’ve tried different sets of USB ports.

Anyone know what else I could do?
