It seem like it's overheating. The card is getting to hot and when it reaches a certain point/temperature it shuts itself off to prevent further damage.

+1

Check ventilation and airflow in your case and/or upgrade the heatsink on the video card

If you have any other old PCs laying around, you could scavenge case fans and mod you case up... I can't get a better shot now, but check out below:

2 power supply fans (one in case blowing out, one in bottom of PS blowing up)
1 case fan at back
1 processor fan on heat sink (ducted, DELL design)
1 front case fan infront of HDDs
1 mid case fan behind HDDs

For now you could take the vid card out and clean out all the dust. Blast it with a can of air. I also use a soft brush (paint brush or makeup brush) to remove dust from the heat sink/fans. Taking the cooler off of the card if you're skilled enough would be better. easier to clean that way. Do the same for the CPU heatsink and fan and any other case fans you may have. I bet you'll see a big improvement.

Removing the heatsink on the CPU and the video card, cleaning it, and using arctic silver may work for a bit, but if there are any underlying airflow issues, it would only be a temp fix.

Check your cable routing
Make sure you have ample airflow
Make sure you have plenty of fans
And if you can, upgrade the heatsink to the videocard

Yeah, that's why I said "for now". But usually, when everything was running fine, and it starts gradually having overheating symptoms over time, it's a sign that there's an accumulation or build up of dust on either the case vents/fans and/or the CPU/video card heat sinks and fans or all of the above.

Another thing to consider, and I'm not sure about the card's capabilities, but to manually control the vid card's fan speed when you're playing your game. If the card is capable Dan, you can access the fan speed control in the Nvidia Control Panel under advanced/performance/device settings/cooling, provided you have the latest drivers. I use an external program to control my fans, but you can do it this way too. Again though, I'm not sure if your card supports variable fan speed control.



As far as adding case fans goes, yes it will help. Make sure you have an equal amount of fans pushing hot air out of the case as you do fans pulling cool air in.

Anyone ruled out the power supply taking a dump? Or maybe the CPU fan not working? Maybe open the case and make sure ALL the fans are working?

True. Good point. A bad PSU can definitely cause random shutdown symptoms, especially when the system is under load (playing games). Yeah a fan not working wouldn't be good either lol

Agreed, and I was not saying otherwise or saying you were wrong or bashing you, just that the symptoms sound like it's overheating due to airflow/cooling issues. Normal oem coolers are terrible compared to the aftermarket stuff available. I ran into this issue when I was running 2 Nvidia cards in SLI mode. It would 1st start to slow down and then shut off all together. Once I got the case fans up to snuff, the airflow corrected (push in front/pull in back), and worked on the cable management, the temps dropped but also Changing the stock coolers also helped considerably.

Now someone mentioned the power supply, and yes that could be suspect as well depending on the max load it can handle. Just depends what the manufacturer recommends to run the card for minimum specs. Always go over if you have the avail. cash. :)

I didn't see it mentioned but do you have the CPU over clocked? I remember my friend haveing the excat same problem he thought it was the video card, but it turned out that he had over clocked the CPU and forgot about it and it was getting too hot. he turned it back to where it is suppose to be and it has been just fine.
