Guild Wars 2

Ok. So, built my own new comp, everything was working fine for awhile, then my video card started artificing and turning off suddenly, freezing the computer.

Sent it back, got a new card. Still kept shutting off suddenly, making a noise like the fan was turning off (a wheezing sorta slowly down). But after that initial stutter, it will play for hours afterwards.

Company was kind enough to send a THIRD card, and still getting the same problems as the second card.

GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130826

Power source: http://www.newegg.com/Product/Product.aspx?Item=N82E16817159126

Since the power source is 700w, that should be enough to run the video card and the processor, so any help as to why it keeps just turning off suddenly, then working fine for awhile?

Note: When the screen locks up after I hear the noise inside, the screen turns either all white, all black, or (once) all green. Then the card shuts off (monitor says loss connection) then turns back on.

Have you considered that the PCI-e slot might be bad on your motherboard or that your power supply might not be functioning correctly to output the correct amount of power?

You can check what voltages your power supply is supplying by using HWMonitor, which can be found here:

At this point, I would say that you have a defective power supply. Coolmax is not a good reliable brand to be using and is probably shutting down before it should be.
