Blackscreen, No Signal, Condensation, Help please.

[OddGreen]

Yesterday I played Battlefield 4 and all of a sudden it froze. The audio failed too and could not see anything on the screen. Tried ctrl+alt+del but to no avail, so I restarted the computer manually.
It started up as normal, and I tried bf4 again, this time I was able to play a bit longer session. But then, crash again. Tried F.E.A.R 1 too, it crashed. I rebooted and got a blackscreen "No Signal Detected!"

My system is only 1 month old, I have built it myself and it has worked fine until now. If I remember correctly, I ran "Heaven benchmark 4.0" some time before I started playing. Maybe this had something to do with my problems? but im pretty sure not.

I use GPU-Z. CPU-Z and HWMonitor to see temps etc, and havn't had any high numbers so far.

Here's my specs:

* BenQ XL2411T monitor
* Corsair C70 Case
* Asrock Z87 Extreme 4 mobo
* Intel i7 4770k
* Corsair H100i CPU-cooler
* Corsair RM 750W PSU
* MSI GTX 780 Gaming
* A-Data SP900 SSD 256gb (OS and BF4)
* A-Data 8x2 16gb 1600MHz
* Seagate 1TB HDD (Games etc)
* Samsung writemaster DVD-burner

NOTE: None of the above are overclocked except the factory OC on the GPU. The H100i is in push and I have 3 Corsair AF fans installed in the case.

Things I have tried so far, but still no signal, is:

- Checked so that there's no bent pins and defect cables.
- Booted the PC with one stick of RAM
- I have reset CMOS as well as taken out and in CMOS battery.
- Tried a different DVI-cable and the second DVI slot on GPU.

The monitor is working fine and it works fine when plugged in to the onboard GPU.
I hope it is some sort of software problem, but I am not surprised if it's hardware related... this is so effin' annyoing...

So, what do you guys think? Should I do a full reformat of the OS? what else can I do? come with suggestions. RMA it? hope not....

One more thing! I noticed some condensation on the GPU fans, as well as on a part on the motherboard. Here's some pictures of it:

Condensation? Are you moving your system from a really cold place to a really warm place? More likely, that Corsair water cooler sprung a leak!!!!

AND, water anywhere in your system will KILL it......

There's no leak in the water cooler. As shown in the pictures, there's only condensation at the GPU fans. Im sitting in my warm room, and it's winter outside. I have openend my balcony door a few times.

Well, in your place you can Not open that balcony door as it causes condensation in your computer.... any water will cause damage.

Unplug the computer, dry up that condensation.... even the smallest bit of water is no good.

You might try relocating the computer to avoid the condensation....

I think it is an oil leak from the GPU, from the fans or heatpipes.. f**k! RMA is probably the only option

Whoa, not cool.

I though CPU & GPU cooler heat pipes were water filled, but, they might add a little something to reduce corrosion....
