Monitor problem

[Tech Wizard]

Hey,

 

Sometimes when I try to launch a game, my PC/monitor freezes. If I have music in the background I still hear it playing, but the monitors are not showing any display. Tried turning them off and on again, but get to the same "no display" screen. I manually have to hold power button untill PC turns off. When booting, I get "overclock failed message" --> "boot windows normally" option. My overclock is stable, already tested it with prime95, CPU-Z etc. Do you perhaps know why screens lose signal after launching games? Thanks in advance

Here are my specs:
GTX 1070 (+100MHz overclock on core. Memory clock untouched)
i7 4930k (4,2GHz OCd @ 1.225V =65c under full load)
24GB DDR3 @ 1866MHz (First 16GB running in quad channel, last 8 running in dual channel)
ASUS X79 Deluxe MOBO

 

OS: Windows 7 - 64bit

2x 24" monitors (ASUS + BenQ)

how are these hooked up, dp, hdmi? did you try going into the nvidia control panel and swapping primary monitors? which monitor is the primary?
