Guild Wars 2

I have the same issue and I tried everything.

I’ll clean my fans.

By the way, I forgot to tell you the sound isn’t looping during the black screen. I can hear the sound in the background like normally.

Lexandro.1456:

Out of date, corrupted or incorrect drivers / Overheating GPU / Defective power supply / Defective GPU and last but not least incorrectly overclocked hardware.

Out of date, I dont know. My config seems OK to play. I saw some people with the same config.
Drivers: I tried 3 different drivers
GPU temp: 60°C at full load
Defective PSU: I thought as well and I changed my PSU 1 week ago for a good one.
And it’s not overclocked.

Maybe defective GPU but I can run OCCT or FurMark for a hour without error or crash.

And last but not least, I can play Hitman or Skyrim in Ultra without crash…

(English isn’t my first language)

Again and again I get this black screen. For months now, I get some black screens while I’ playing. What exactly happens:
-The game freezes for 2 sec then I got a black screen for few seconds and then there are two cases: First my game back to normal. Second my screen stays black and when I check the task manager it says no response and I have to stop the process.
The more I increase the graphic settings the more the crashes are recurrent but even when I’m playing with low graphism I get some crashes. The frequency varies, I can get 5 crashes in 1 minute or 1 crash in 5 hours.

I’ve tried:
-I tried different GPU drivers (old, recent and beta) with a clean uninstall every time
-I disconnected and reconnected my video card.
-I tried overdriveAMD ON and OFF with different parameters
-I updated my motherboard chipsets.
-I did a memtest, I got no error.
-I did a OCCT GPU, CPU, Power Supply, I got no error, crash or extreme °C.
-I tested the 12v of my PSU with a multimeter and at full load I got 12.01v.
-I tried all the advices from technicians. (the settings of ATI, AA, use application mode, …)
-I deleted the file local.dat
-I did a repair-
-I think I tried other things but I don’t remember.

My config:
- HD7770
- Windows 7 64 bit
- Intel E8400
- 550W PSU with two 12V rails 30A (440W max)
- 8GB of ram

I’m running out of ideas, patience and it starts to be really annoying to have to play in low to be able to play as much as possible without crash.

If someone has an idea, I’ll try with pleasure
