Computer turned itself off, wouldn't power back on, but now working?

Hi, roughly two-months ago I built myself a new gaming PC, something I have done in the past, as my current laptop wasn't able to properly preform the games I wanted it to. All was going well since then, until today, today I was playing TERA, and suddenly my PC shut off. I wasn't quite sure what caused the issue, so I attempted to reboot my PC. When I pressed the power button I saw my fan-light start up, and it began to spin for about 1-3 seconds, but then stopped spinning and its light turned off. I then tried turning it on 3 more times, but each time ended with the same results. This lead me to believe it may be a power-related issue, so I then waited about 5 minutes and tried it again, and now it is running again. I am quite dumbfounded as to which part caused the problem and needs to be replaced. I THINK this is a power-supply related problem, since the fans would light, start spinning and then stop, however, it may also be possible that this is some other issue all together.

I am really unsure of what the problem is at this point in time, and I was hoping someone could try to enlighten me as to what they believe may be the cause. If anyone has any suggestions or information they would like to share, it would be much appreciated.
 
Solution


I ran 3DMark11 and my CPU peaked at 68.5 C and my GPU peaked at 77 C. I wasn't able to recreate the problem, though.
(I used Open Hardware Monitor for the temperatures.)


I'm still running with the stock cooler, maybe that's why? I'm not so sure, do you have any advice?
Could be a short (part of the case touching a part of the board) that caused it. Could be a sign the PSU isn't powerful enough and you caused it to fail when pushed. I would say Video Card overstressed and overheated the case possibly too, since it took a while (cool down) then was working again.

So I would run a benchmark and monitor CPU / GPU temps and see if you can recreate the problem.

I'm going to try running 3DMark11, check my temps and possibly recreate the problem. (If there is a better benchmark or method of testing this, please let me know.)



I ran TERA again, after this problem happened earlier, and didn't run into any issues, but my temps at the time were around:
CPU 65-70 C and GPU 70-75 C.
