Suddenly Getting Frequent Boot Failures?

[Aleksbgbg]

My PC is relatively new, about 4 months old. My boot drive is a Samsung 850 EVO 250GB SSD, currently with 72GB free space.

 

When starting my PC from sleep a few days ago, I got a boot failure message. The PC restarted and everything was fine. Following that, every few startups, the PC will not give any video output for a few minutes, which is when I would restart it, and then it boots as usual with 10 seconds of boot time.

 

Why is this happening and how do I fix it?

I don't remember that well now, but it said that there was a boot failure and that I could either (from options on screen): keep settings; reset BIOS; shut down

 

and I will try that
