Windows 10: Windows 10 not rebooting after blackscreen

Have been using Windows 10 for about a week without any major issues. Today while in IE screen went black for a couple seconds, then returned to IE, but cursor didn't respond. Then screen went black and stayed black with "DVI", "HDMI", and "VGA" icons appearing sequentially in upper right hand corner, then "no signal". Large white cursor arrow on screen responding to mouse. CLT, ALT, Delete did not work. Manually powered down and repowered. Initial blue HP screen appears, but nothing further. I am a "basic" computer user, so simple directions would be much appreciated.

Blend test with Prime95 causes BSOD

Hello,

I just built an high End PC with Win 10 and get Blackscreen when I'm playing and when I'm doing a blend test with Prime95.

The Blackscreen its just black and then reboot. No message or something. After reboot everthing is fine.

So I got out that just 1 of my 8gb DDR4 Ripjaw 5 is running all properly (with the non working one Windows is still booting and without blendtest or games everything is fine). So I tested the RAM with the Windows Utily and with Memtest86 and everything seems
fine.

Tomorrow I'll give other RAM the try (4x8gb DDR from Corsair).

Pecs:

Asus Z170 Pro Gaming

Intel I7-6700K

Nvidia GTX980-ti

G-Skill 2x8gb DDR4 2133 MHz Ripjaw V

Samsung 850 Pro 512gb
