Hi! It's been 3 days since I have completed building my computer. However, just an hour ago, something strange happened. While watching a YouTube video, the screen suddenly went black and the [No Signal] display was shown. Nothing was showing. The audio sounded "stuck" and distorted as if the last sound was stayed on. The computer was indeed running, so I doubt it was the PSU. Then the computer rebooted itself. As soon as I opened Google Chrome, the display disconnected again. This would happen a few times, whether or not a program was open. Since the first one, I had to press the reset button and display turns back on. An hour has passed and everything seems sound now, but I was wondering what could have cause that and if there was really a problem with my PC. I ran Prime95 and a CPU temperature of 72C seems fine. While running 3Dmark demo with the Starcraft spoof thing. The HDMI signal was lost. Sound continued until the end. From there I had the reboot the pc

Reading the logs, the things the seemed weird were
Display driver nvlddmkm stopped responding and has successfully recovered.
The following boot-start or system-start driver(s) did not load:

When connecting the PSU to the motherboard, I had some difficulty plugging in the 20+4 pins. There was no snap. I pushed really hard to the point where I fear I may break the board. It is as far as it can go with my other hand providing counter force to make sure the board doesn't bend.

Some thing you should try: wiggle the plug left and right until it snaps in, if it doesn't, then you have either defective PSU plugs or defective mobo power sockets.

But they way this looks like is as if the graphics card crumbles under load, see if you plugged the cables in properly there... there could also be a problem that your 12v rail on the PSU doesn't give her enough juice. Check your graphics card's power requirements and how much power your 12v rail provides.

I don't know about that. I am able to run Watch Dogs just fine on high, not ultra (probably due to it not being optimized I hope is the problrm) and a couple of other games on max settings just fine.
