Games crashing after new GPU install

Hello

I recently purchased and installed the KFA2 GeForce GTX 770 LTD OC 2048MB GDDR5 PCI-Express Graphics Card in my rig and everything works fine except when playing games such as Assassin's Creed Black Flag or Arkham Origins or even World of Warcraft after close to an hour of play the screen turns black saying there is no signal to the monitor and it wont respond to any input. Sometimes it will simply crash to desktop and I can hear the sound from the game through the speakers as though it was still running. It doesn't always happen and it and i can't say for sure what might be triggering it. Once when it crashed to desktop I noticed, while i was running MSI Afterburner, that the GPU usage spiked up to 100%. I have tried using MSI Afterburner to increase fan speed thinking it may be overheating but that doesn't help and it has happened shortly after start up before. Can anyone suggest what might be happening here or something i can check/test or try?

I am pretty sure it is caused by overheating. I would manually set your fan speeds and monitor you temps (with HWMonitor)

Hi Quasty

Thanks for your suggestion, i tried it last night with my fans on 75% and i set the graphics options on a lower setting playing Black Flag to see if that helped but it still crashed after about an hour of play, the inside of the rig seemed pretty cool to the touch as well. Just as a side question, are there any negative implications with putting my GPU fans on 100%?

WAIT, I just realized that you are still using the stock cooler !? No wonder you pc is overheating! You should look into your temps on your i7 (they should never exceed 70 degrees!! And if it heats up fast, get an aftermarket heatsink.

Ok so after much investigation and testing i found the problem. Turns out the card was factory overclocked and due to the GPU being faulty it could not keep up with the higher memory clock speed. I figured this out by down clocking the card and running as normal. After it stopped crashing with the down clocked profile i asked the manufacturer (KFA2) for advice and they said to send it in which i did and they confirmed that the GPU was faulty (apparently it died half way through their benchmark process). So that answers that question but now i have been in the unfortunate situation of being without a card for over a month as KFA2/Galaxy don't have stock of my particular model and don't know when they are likely to get more. I have been in constant contact with them and was even told that i could have an upgrade instead of my original to compensate me for having waited so long but since that none of my communications with them have been answered. It's kinda sad as i was really impressed with thier customer service up to that point. Anyway hopefully this can assist someone having a similar problem and serve as a warning about KFA2's RMA process.
