PC restarting by itself

Hello,

About a month ago I bought and assembled my first ever gaming PC. However whenever I play Guild Wars 2 my PC sometimes restarts by itself usually in areas with high activity. I don't think it's a temperature problem since I downloaded a temperature reader and it all seemed cool on the inside. Could it be an issue w/ the power supply not being enough or a problem with the motherboard. Could it also be a problem with the outlet it's connected to?

My system specs are:

stress test your cpu using prime 95, have core temps to see the temperatures. if your system doesnt freeze/crash its not your cpu
benchmark your gpu by using furmark, if you dont see any graphical artifacts then its not your gpu either

550w is enough for your build

you can also check your ram for error by using memtest program (you have to burn and boot from the cd)
