Could be numerous things.. you said it's a new computer so I'd send it back, just to be safe. Also, that computer must have cost $3000+.. what in the world could you use all of that hardware for? I'm running Phenom II X6 1090T @ 4.0GHz, 6GB DDR3 @ 1600, 120GB SSD + 1TB HDD Raid 0, and a HD 5970 @ 1GB GDDR5; I can run every game on max (including Crysis and Metro 2033 @ a solid 50FPS).. x2 580's is overkill, along with 12GB of DDR3 RAM, because I (running W7 Ultimate 64-bit) don't ever get past using 5GB of DDR3.. and that was when I was testing the RAM, opening as many programs as possible. You i7 is nice, but you could have saved $1000 and went with a i7 4-core, then when you needed an upgrade (years from now) instead of spending $500 on another processor you could just overclock to 4.0GHz and it'd be equivalent. I'm not sure why people go overkill with their home computers.. I've seen a YouTube video of someone that had x4 580's, x2 Intel Xeons, 32GB DDR3, x2 1100W PSU, full watercooling. He overclocked each GPU and CPU, along with the RAM. Why? He says: "so I can run Metro 2033 on max settings with 100+FPS". My question: "How is $10,000 ($1,500+ for that matter) worth playing 1 game on maximum?" However.. I guess if you have the money, you might as well; but $10,000 can buy a decent new car along with a pretty strong computer.. my computer was only $1200 and I can run everything on max settings like I said.. I also won't need to upgrade for years to come as more programs will take use of all 6 of my cores in the future.. Anyways, sounds like hardware failure.. I'd return it but if you don't want to waste time (understandable, my PSU was back ordered so I had the whole computer built a month before I could use it) I'd recommend getting your own water cooling system and installing it yourself, depending on how experienced you are you could also go with Best Buy.. they'd install it for $30-50 and give you a few months warranty (if it ever broke again).

since its new and covered under warrenty instead of running any risk at all damaging just send it back i know you are probally god with computers but just send it back to be safe
