It could be a problem with your graphics card, try upgrading all of the drivers if you haven't already

If you hear the fan getting louder, it could be a heating issue.
Try checking your temperatures. If it works fine and then it stops it definitely might be a cooling issue. Especially check the video card if you hear its fans going.

If not, then try using the computer without the graphics card. If the problem stops then your video card is bad.

Is the pc just turning off or just restarting? If it is just turning all the way off it is probably a heating issue. If it is just restarting it sounds like a problem that I had a few builds ago. After testing all the hardware, I ran memtest86 and found 40,000 errors in the first minute. Use this to test the memory and make sure it is good.
