I have a build here that's being really odd. The concerned components are a Gigabyte GA-Z87-D3HP motherboard with an i3-4130 on it. Windows 7 is installed and running flawlessly. I've burn tested (prime95, fur mark, etc...) the heck out of it for a few consecutive days now, and not a single error, lag, bluescreen, or otherwise. The problem I have is that I can cold start the computer, I can shut down the computer, but I cannot restart. If I attempt to restart, Windows shuts down, then I get a black screen, and it just hangs there indefinately. If I hold the power button to force it to shutdown, then cold start it again, it starts as if it had expected to continue its restart. No errors, no bluescreen. Its almost as if Windows is sending the command to restart to the motherboard and the motherboard is just ignoring it. Windows having done its part no longer exists, hence the dead black screen. That's what I can tell anyway. Has anyone experienced this? Anyone have an idea? Maybe I need a Microsoft hotfix? Or maybe I just need to sit it out and wait for Gigabyte to release a BIOS update?
