Guild Wars 2

Maybe try uninstalling the driver, go into safe mode and run a tool like Driver Sweeper from guru3d.com and clean up any residual registry and file entries then reload from scratch. It may be some leftover settings that are not kosher with the new card for some reason. I suppose it is possible that power is the issue, but it seems odd that it would be a factor when you aren’t pushing the card at all (3d gaming) and that it works fine when using a default VGA driver.

I would boot to Safe Mode and run the uninstaller for the current drivers you have. Being you have a card with several generations difference, it may be trying to run those old drivers with the new card and failing. After you uninstall in safe mode, reboot to normal mode and it will likely come up in VGA mode ready for you to install fresh new drivers. The power supply MAY be an issue during gameplay for stability, but that small difference shouldn’t be a factor when running in non-3d mode.

Well it may not be the fix in your case, but for me I was running out of options and figured I’d try it. I’ve had my system a while though so I’ve upgraded video drivers many times. You run it under safe mode so that only native VGA drivers are loaded, not the specific video card drivers and since you already have done the step to uninstall the current drivers before running this, it will scan for rogue files and registry keys related to the brand of driver (NVidia/AMD) and clean them all out. You then boot back to Windows normal mode and reinstall the latest drivers fresh. Hope it helps, as it did for me, but I’m sure it’s not necessarily the same issue with everyone, seems too easy for that. Hopefully though some that try it are successful like I was.

If some of the other suggestions like underclocking, cleaning the fan/heatsinks from dust, re-seating the heatsinks with new thermal paste, etc don’t help, try this, I had the same problem and nothing worked until I used this tool.

Follow the steps as instructed. Won’t hurt to try even if it isn’t the fix. Make sure to run it as administrator if on Vista/7. After you’re done, reboot to normal Windows mode and reload the current newest drivers.

I had the same issue with an ATi/AMD card and I used this driver sweeper and the problem has gone away.

Hope it helps, it may not be the global fix for everyone, but it definitely worked in my situation after trying tons of things both software and hardware related.

I had the same black screen issue, sometimes it would come back , sometimes not and the game would crash and force me to restart it to play. I tried tons of stuff related to heat, clock speeds, voltage, etc., no luck. Reloaded drivers, went to lower versions, etc. Nothing worked. Decided to give Driver Sweeper a shot and wow it worked. 3-4 days now with no black screens at all (Was multiple times a session previously). Try it out, might not be the answer for everyone, but it totally worked for me.
