There's no beep code, no display or output. My old computer had an MBR problem with no display, all I have as a boot media is a system builder for Windows 8.1. New build to fix that and give the computer to somebody (the old one). I have an i5 4670k with a Cooler Master Hyper 212 Evo cooler,Kingston v300 120 GB SSD which is a bait and trap scheme but whatever, a CX750 PSU, a MSI Z87 GD65, a Seagate Barracuda 2 TB HDD, 3 normal (plain black) Corsaur fans that came with my C70 case and 4 SP120s, an LG DVD drive, a MSI R9 270X, and a NZXT Sentry 2 fan controller.
