  1. Tough one this. Can you test the card in another PC?
  2. what's the temperature of your video card?
  3. Might be that your motherboard's PCI-E lanes are going down the drain.
  4. It is possible that your board could be the problem and I have had it happen once my self but I am leaning towards the card being faulty. Did you overclock the card and game for long periods of time? XFX used very cheap low grade SMD mounted ferrite shielded inductors and they degrade fast especially when fully loaded and overclocked.

    no i dont overclock it.but while playing i select the graphics overdrive option to keep the fan speed at 100%.the other clocks remain at factory settings of 1025 and 1150

    okay
  11. it sounds like its running hot mine doesn't usually go over 53c 100% load with my fans at 50%. id download msi afterburner and monitor your gpu usage temps and fan speeds there. are the drivers updated?

    that temp is normal. i always run my hd7770 at 60 degrees celcius when gpu at load and never had a problem for many months now.

    who is your card manufacturer?
  18. My video card is Sapphire Vapor X HD 7770 OC edition. Try disabling the overclock option. Everytime i change one of those it made my video card unstable. Well its because mine is already OCed.
