PC restarts when playing games

So about a week ago, I installed Bioshock and played it up until you enter rapture when my pc suddenly restarted. I played it again a few more times and the same thing keeps happening. I tried to play Bioshock Infinite (a newer game which I have played and finished before in the same rig) and the pc immediately restarts when I start a new game. I don't think that it's a temp problem as I've been monitoring the temps as I'm playing these games (all below 50 C) and they restart my pc immediately before I can even play long enough to get the temps that high (if they even get that high).

I cleaned out my pc of any dust in the fans and after that, for some reason, my 9800 gtx+ gpu stops working. Therefore, I believed that it was an issue with my gpu, so I bought a new 770 gtx. After installing it, monitoring the temps, the same issue happened when I attempted to play the same games, and even on my other existing games that I've had no issue with before. I've updated my drivers to the latest ones to no avail.

Here are my specs:
-Intel i5 3570k 3.4 ghz
-G.SKILL Ripjaws Series 8G 841 mhz
-Seagate Barracuda ST1000DM003 1TB 7200 RPM
-motherboard: GIGABYTE GA-Z77-D3H LGA
-770 GTX nvidia
-PSU: Rosewill Green Series RG630-S12 630W Continuous @40°C,80 PLUS BRONZE Certified

I have a feeling that it might be my PSU not being able to handle the new graphics card, but it was happening with my old graphics card anyways so I'm not sure. Any suggestions?

  1. Ok first download "WhoCrashed" and when it happens again, run this program and it will tell you exactly what the error is and what might have caused it. Try to install it right now and play bioshock, then after restarting the computer run the program.
  2. Its probably the cpu getting hot. Maybe poor cooling. maybe poor voltagecontrol - from psu or mobo.

    Have you overclocked the cpu?

    What cooler have you got on the cpu?
    If its not a custom cooler think about getting one eg coolermaster hyper 212 evo.

    Can you download and run HWInfo - Sensors and post the results? usually 3 screenshots on TinyPic or similar. Then I can see voltages etc

    Have a look at - to see how your psu is rated.
  3. Mojojojo - I installed and ran the program right after my computer restarted and it did not identify the restart as a computer crash, so I'm guessing that it's not a driver problem

    i7baby - like I said, I don't think that it's a temp problem as I've been monitoring the temps as I start my games and have seen nothing go over 50 C. No, I have not overclocked anything, and I don't have any extra coolers for my cpu. I will try the HWInfo and post the info. My psu is a Rosewill brand and was not specifically stated by the list you provided.
