Screen turning black for 3ish seconds after I turn it on

I recently build this computer the other day and this is the parts.

I7 2600k @ 4.9 GHZ 24+ hrs of benchmarking.
16gb Cas 7 DDR3 1600
H100 Corsair
ASUS Nvidia 570 GTX running @ 980MHz core, 24hrs of benchmarking.
System stays cool in idle or when screen flickers ONCE after I turn it on, under 30c, both CPU/GPU.
ASUS P8Z68-V LE LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
Corsair HX750 Modular PSU

This is a walkthrough of what happens, and when:

At night I shut off the computer, next day I turn it on, and I start a game like World Of Warcraft or Battlefield 3. About 1-2 seconds after I start it, the screen TURNS BLACK for about 1-3 seconds then back to normal.

Please help me fix this or troubleshoot it, its never done this before, I had a very similar rig before and I did the same exact installation steps other than a new i7 with higher overclocking on CPU/CPU!

More about screen turning black 3ish seconds turn
  1. Anyone? I took all the overclocks off, it still does it but not right away, later on while playing
  2. If anyone wants to respond then they will do so in their own time, bumping your thread will just result in its closure.
