PC Suddenly needs restart?

[McKennan McCall]

Well I just built my PC, and everything was going fine..Until last night..I tried to play Watch_Dogs. I tried to plug in my head phones (Using HDMI for sound/video), and so I had to bring my tower closer. As soon as I moved it, my display went out, along with my sound. (I'm using a flat screen Sony TV as my monitor) I tried doing my on board VGA. Nothing. After I restart my PC, things go back to normal. I was just on chrome listening to music, and then I moved my computer the slightest bit, and then it happened again.

sounds like a bad/loose video cord.

I would upgrade the PSU also at a later date.

I already said I tried VGA and HDMI on my motherboard too

Yes, I've heard that these PSUs aren't that great in lasting, but I've only had it for almost a week.
