Black screen silliness

[honegod]

In windows 10 the entire screen started jumping up and down a pixl or two, a white line appearing and disappearing at the bottom of the screen.
Then the screen went black.
I pushed the power button to shut down, waited a moment then pushed it again to restart.
Up came the bios screen.
Into the windows login screen, logged in.
And it went black again.
Shutdown, pulled the videocard, plugged the HDMI into the motherboard.
Restart, bios fine, login fine , black screen.

So I do not think it's the videocard, cable, or tv.

Does this sound at all familiar ?

since I did a backup of the os onto a separate drive last week, I rebooted onto that drive and os, and presto the screen is back.
so it sounds like a software glitch.
since both OSs have the exact same software
is there a nvidia software that takes over video when windows is logged into ?
login screen works, then goes black upon hitting enter.
it did the same thing using the intel video on the motherboard though.

hmm, since it seems to be happening with both IGP and discrete GPU it's bit strange, did you try booting into safe mode? should not load drivers, see if that makes a difference.

You could also try a xlear CMOS to see if that does anything, make sure to note all changes you made b4.

I have two m.2 drives, each with a clone of my C drive.
the original on a 960evo, and the clone on a 970pro.
I did the cloning a week ago and have been running the clone 970 as C since.
it is the 970 that is doing the black screen thing.
so I changed the boot order to boot into the original 960 and it worked as it should.
so either the 970 is broke or the clone is broke.

so I REcloned the 960 onto the 970 and am running it now just fine.
so it looks like it is a Windows problem.

unless it happens again in a week.
we'll see.
