Black On Occasion, happens certain times

[Razor]

Using windows 10 for months, this problem has only being happen with in the last few weeks.

The problem is the when i turn on the computer it Bios menu where if you press a delete you ever the bios menu not the problem this is what it should do, but it only shows for about a second then screen goes black for about a minute then your at the lock screen. That's the problem it doesn't show windows logo just goes straight to lock screen.

It happens other times too one example that i can recreate is when in the Netflix app when i go to switch user screen goes black again have been able to fix this issue by switching hmdi cable from display output from GPU to integrated intel graphics. That fixes that particular issue but not the first.

Any help would be great

Press Windows key + P

Choose another projection, press Windows key + P again, then choose your default projection.

I would also check to make chipset and video drivers are updated.
