I would try clearing cmos on the motherboard. I can't tell you why this has worked for people but for some it has. For the bios, if you boot to Windows and you hold shift and click power and restart it shows a blue screen where you have options to click. Go to troubleshoot, advanced options, then UEFI firmware settings. This should boot to bios. If this does not work then I would assume its a display out issue.
