Will it still power up with nothing installed? I know it won't post, but I'd expect it'd at least give a code. Is every motherboard different for this? Does doing this harm it them in any way? What's the process to properly test a motherboard and it's hardware being installed? Is there a standard step by step procedure? Can defective hardware damage a motherboard or vise versa? I'm breadboarding a Asrock Fatal1ty 990FX Pro and want to take care not to damage anything.
