Hey, guys - first time posting here. I'm fairly new to building computers and purchased an MSI N770 2gb video card, like the one pictured here: http://www.amazon.com/MSI-GeForce-PCI-Express-N770-2GD5-OC/dp/B00ENU2K7O/ref=sr_1_3?ie=UTF8&qid=1411440009&sr=8-3&keywords=MSI+N770

The problem is that when playing certain games my monitor will turn black and the sound will stutter for a moment before shutting off. I'm then forced to manually shut down the computer, which only takes a tap of the button at that point. I've tried uninstalling and reinstalling the drivers numerous times, and I've monitored the heat of both my CPU and GPU and it's well within the boundaries of safety for both components.

Specs:
MSI Geforce N770
Intel i5 4670k
Kingston 120gb SSD
EVGA Nex 750G power supply
MSI Z87-G41 MOBO
G.SKILL Ripjaws X Series 16GB (2x8gb) 240-Pin DDR3 SDRAM DDR3 2400
OS: Vista

Everything is at stock settings. Most games run fine with little issue, but some of the heavier ones will run totally fun all day, but crash within 30 seconds or a few hours on other days.
For the 14-pin video card, should I run two separate cables from the PSU? Or should I use the same cable that has both an 8-pin and 6-pin connected to it?

Thanks for any and all help.

Blafrom, you mention the problem happens on 'certain games'. What games? Have you checked the actual game site forums to see if there is a history of complaints about problems similar to yours? It is not uncommon for games to be released before they are ready for prime time and have problems with video especially. Usually, the gaming site will tell you to update your video drivers which may or may not just be a delaying tactic to give them time to figure out the problem. Also, are those particular games kept updated? If they're on Steam, make sure you have updates turned ON, if they are boxed games, check for updates. Another thing to check is your memory. D/L memtest86 and check your RAM, it will take several hours to...

I currently have a 770 with a 750w power supply so the wattage isn't the problem. I do recommend to run two sepperate PCI-E plugs into the card itself. One 8-pin and another 6-pin. If that doesn't work always make sure the card is firmly and correctly placed in to the PCI slot on the motherboard. Also, make sure that the HDMI is in correctly (Should have nothing to do with it).

Thanks for the responses, guys. I actually use a DVI-D cable to connect my monitor to the card, and it seems to be firmly in place. Same with the connections to the PSU and GPU. I've updated my OS to Windows 8 and have uninstalled and reinstalled the drivers and a series of different fashions. Nothing seems to alleviate the problem. Can I be sure my graphics card is getting ample power?

The 770 recommends 600w to run. You are using 750w which is an awesome amount for your rig. If your sure its something to do with the power source, make sure the PCI-E are plugged in correctly from the PSU to the Graphics card.
Also remember, there is a 4-pin connector and a 6-pin. Don't forget that 6-pin. If that doesn't work it must be faulty. Hopefully you can RMA it for a new one. (I would personally just RMA it now)

D/L memtest86 and check your RAM, it will take several hours to run but it COULD be a source of your problem. http://www.memtest86.com/
Also, check your sysconfig startup to make sure you don't have unneeded, extraneous programs running in the background when booting up.
I've done all of above and eliminated a few problems by these methods.
Good Luck :)
