Artifacts in game and system crashing

[Pankaic]

So recently, my computer has been having some really bad crashing problems. This only occurred when playing cs:go, which is honestly the most intensive game I play. At first, I though it could be my components overheating, so I turned off my overclocks on my CPU and GPU, and began monitoring their temps. Not being that straining of a game, my temps were fine, never going above 80 C for the GPU, and 70 C for the CPU, but my system was still crashing occasionally. What else could be the cause? My card is still under warranty, so should I try getting a replacement?

 

System specs are in my sig.
