So I recently built my first gaming PC and have been having a lot of trouble over the past week with my build. one problem in particular is that my system keeps randomly rebooting. This random reboot usually occurs when i'm playing games however it has occurred once when I was just browsing Google for this issue. Basically I will be playing a game and suddenly my PC freezes, goes on a sound loop of the last noise played and then restarts itself. I have tried many software related fixes all having no effect and today i tried switching my PSU out with another of equal voltage and no luck. This usually occurs within 1-3 hours of gaming, but not during stress tests like fire strike. I've watched my temps while gaming and my CPU does not go over 40 and my GPU hovers at 71(Celsius) all while gaming. My GPU came factory overclocked and this kind of leads me to believe it is not stable. I also have an important update for windows that will not update. I have tried to manually update it, however nothing works. I'm down to the graphics card at this point but am anxious to here any and all solutions to this problem you may have. Thanks.
