[ommmishra]

Justa week ago I built anew computer. while gaming just after a cutscene the screen goes black but the sound keeps on playing normally, it happens both in witcher 3 and gta 5. The case also seems to be somewhat too hot. I am having this problem from day one.
my specs are :
intel core i5 6600 processor
gigabyte z170x gaming 3 motherboard
corsair vengeance 2400mhz RAM
zotac gtx 1070 amp extreme graphics card
corsair cx600 psu
corsair 100r case

Have you tried other games ?
Did you get the "display driver stopped responding" message ?
Also, what is the temperature of the GPU & CPU while gaming ?

I didn't get a message like that. But arter it turns black, I switch the monitor off and then back on, and the screen appears normally. Also the screen flickers before going to a loading screen. I am using a 1600x900 resolution monitor with a hdmi to vga converter.
