So I recently bought new PC parts. Put everything in plugged it all in and powered it on. Only light in the whole case that turned on was an LED line that ran across the motherboard. All the cables are plugged in. Even unplugged them and plug them back in to make sure all the cables are plugged in. Tried replacing the power switch with the reset switch nothing happened. Don’t know what to do I don’t know if something is broken. Please help!!
