I'm sure I fastened all cables correctly, and referenced multiple user guides for each individual part, and my new computer is not going into BIOS at all. It's an MSI Z87-G45 mobo with a Rosewill Capstone 750w PSU, 2x Corsair 8GB RAM. Fresh pieces, all of it, so there's not even an operating system on the hard drive, which still wouldn't affect the ability to go into BIOS.
If there's other information needed I'd be more than happy to give it.
