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" 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. 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.

Update: Just an update. 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:

Probably a motherboard or psu problem. The psu could be randomly having wattage fluctuations. You could replace the psu or plugging the psu directly into a wall socket.
