When I start my computer up everything seems to be running fine. The fans, the RGB strips, everything is on however there is no display to my monitor and everything in the back doesn't seem like it is working (usb and other ports). Every time I plug a mouse in it does not turn on. I don't know what to do because the other day my PC was working fine and i was able to use it but this morning I turned it on and there was no display at all.

AMD Ryzen 5 2600
MSI Radeon RX 580
