PC Shuts off during gameplay

67C is pretty hot. Still, it should trottle , not shut down your PC. I think it is more likely your graphic card overheats. Monitor its temperature.
EDIT: 67C is still under max temperature.

Thermal and Power Specs:
Maximum GPU Temperature (in C) 100C
Maximum Graphics Card Power (W) 116W
Minimum System Power Requirement (W) 400W

This is from the nvidia website. 67C is not rare for a GPU. YOu should worry if it gets like 85 + celcius. YOu should check the airflow of your case maby its messed up and hot air not flowing out of the case but building up inside your case. I would contact newegg if the problem stil persists

My first point of call would be to contact NEWEGG if it's under warranty, don't do anything to compremise your warranty, my gut feel is that it's either GPU or PSU related. If it's under warranty then they have an obligation to address the issue and be given the opportunity to put it right.

If your PC is out of warranty........ Either the PSU is struggling to supply enough power at peak loads under prolonged periods and cutting out or the GPU is over heating. PSU is most likely an issue if you have a no brand power supply or it's a low power PSU and you are running a high power GPU and CPU. What's your venitlation and airflow like through the case? Try removing a side panel and see if that helps. When you do this (with the power off) check your motherboard and GPU for dust and clean as appropriate, note it's also worth checking all case fans at the same time). Run diagnostic software to check the temp of your GPU.

i am supposed to be getting a new video card and power supply, and at the moment i have the side panel removed with my air conditioner blowing cold air in and my fan sucking hot air out. i have also checked for dust and nothing at all, and all fans are working. im not sure what brand the power supply is but its 700Watts. i thought that would be more then enough but then again im not a computer technician  

It is the GPU RAM.

There is no monitor for it. The fact that keeping it cool makes it so you can play without issue verifies that it is a heat issue.

RMA the GFX card stating the GDDR is overheating and describe the problem and solution (A/C helps keep it working).

If you are out of warrenty then you can try to find a 3rd party GPU cooler that has "full coverage" H/S.

I assume your current GPU has a "flower" style cooler. If you already have a full coverage H/S then it is likely a thermal pad is missing and preventing heat from the GDDR transferring to the H/S. You can buy new pads and install them to possibly fix it...

What?, did you guys not hear a thing chinchilla said?. Since this is a Computer still under warranty... newegg should have the ball. Before replacing ANY hardware. Let Newegg trouble shoot. if problem still not solved then take matter into your own hands. Change out Graphics card and Power supply. POwer Supply first. But let me ask this what res monitor are you using Suspect?, I used to run a 550 ti (Disliked it very much) at 1600x900 my GTS 450 did better. when i ran 1920x1080. my 550 ti was still doing the exact same thing your computer is doing, even with a 750 watt Corsair power supply. SO i tryed the GTS 450, and it would almost seem like it was gonna crash and would lagg a little bit it worked better than the 550 ti. SO over tiem i got two 560 ti's and problem solved.

This sounds like it could be a plain ole memory issue, maybe a dimm came loose during shipping. I would try re-seating the memory. If that doesn't do it run http://www.memtest.org/ just to make sure the systems memory is fine.

Those are easy and free options but if those done work I would work it out with newegg or the manufacturer as it sounds like its a defect of some kind. Also, almost every person on newegg has this issue with the PC.

james is right. Read the reviews: 2 egg average, 57% 1 and 2 eggs. That is what we call an "indicator".

Just out of curiosity, S_s, what kind of power supply does the system have?

Your symptoms match those caused by inadequate power.

Umm, Newegg doesn't provide the warranty

Im using my TV its 42" and 1920x1080

at the time i didnt think to read the reviews( dumb i know ), i just wanted a better computer. but after i got it i read the reviews and i re-seated the RAM. cleaned any possible dust. moved to a better area. bought artic silver 5 thermal compound and replaced it to the cpu and video card. still no improvements. and the side of the power supply says " 700W ATX power supply www.buyxg.com "

THE FACT THAT PUTTING AN A/C ON IT FIXES THE PROBLEM CONFIRMS IT IS A HEAT ISSUE

^^^ DUH, GENIUSES.
