I decided to build a pc and I made sure that I followed the right steps to build it, I connected every single PSU cable I need to connect as well as the I/O front panel. When I was done building the PC I tested it at night and saw that all the components that have RGB light up. The next day I got my monitor and tried connecting everything, but nothing seemed to connect to the motherboard I/O ports. My keyboard and mouse don't light up and I tried every USB port there is. I've tried other many things like disconnecting and reconnecting. Is there a way my motherboard is damaged, pls help!!!!
