I built this PC a while ago (see: http://pcpartpicker.com/list/Y7pV4C for build details). MB is an Asrock Fatality Z170 i7. MB was purchased in June 2016 and I've never upgraded the bios as there were no problems.
Computer was working fine for several months. Today I needed to reboot it and when it booted back to windows the USB mouse and KB weren't working. Has happened before, the solution is usually to unplug them and replug into different USB port, and then reboot.
This time, when I tried to reboot, it refused. It gets to the BIOS setup screen just fine, but after that it just displays a blinking cursor on a black screen and doesn't continue to OS boot. I can enter BIOS setup just fine. Note that mouse and KB work just fine in BIOS setup.
Things I've tried: Resetting UEFI defaults, switching to back-up bios (Bios A/B switch), clearing CMOS (using jumper), reseating the boot drive (Samsung 950 in an m.2 slot), reseating RAM, leaving computer powered down for a while (in case it's a heat issue).
EDIT to add: Also tried removing graphics card (and running off on-board graphics), removing all hard drives other than boot drive.
None of the above helped.
Ideas?
Thanks.
