MSI gtx 780 lighting causing pc to crash please help

here are the specs of my build
-mb: asrock extreme 4
-ram: 2 8gb crucial hyperx 1600mhz
-cpu: i7 4770k
-graphics card: msi gtx 780 lightning edition
-psu: xfx 850watt 80+ gold rated fully modular power supply
-case: NZXT phantom 410

i am not really too sure as yo why this is happening im guessing it maybe overheating and shutting down the pc to prevent damage but it only happens while im playing games sometimes i can be be in a game for 2 hours straight with no issues what so ever then all of a sudden it'll just crash. the way i figured out it was the video card causing the crashes was because i did a stress test with msi kombuster and after being about 5 seconds into the test the screen goes gray the fans get extremely loud and fast then it just restarts.

    Have you attempted to overclock the card, because overclocks that are too unstable tend to be the reason for things like that.
  2. have you checked the current (amps) requirement of your GPU vs the current (amps) rating for your PSU?
  3. I would suggest making sure drivers are fully updated, and underclocking the card a bit to see if it works.
  4. too be honest i tried it once but assumed since that caused a crash it went back to it default settings im new to the whole overclocking thing so how would i reset it back to its factory settings ? besides it was fine for like 2 weeks and then when i had tried overclocking it, it only happened like a week ago and these crashes only started about 3 days ago thats what doesnt make sense and it making me think maybe the card is defective or something ?
  5. do i underclock the core clock ? or memory clock ?

    There should be a big button with Default written somewhere..... If not have a look on Google. And its probably not a faulty card, its just when the stress on the card becomes a lot it crashes to prevent it breaking :).
  7. okay i hit reset so now do i just restart system and see if it still crashes during a stress test ?
  8. okay so i just tried to run a game and the system crashed and as it came back on after restart on the screen there were graphical glitches of bright green and pink on the screen which leads me to think that there is something wrong/defective with the card

    Ok well in that case I would contact MSI customer support and explain the problem. Sorry I couldn't help, but now you've said that it does sound faulty.
