Error code 43 on gtx780 after driver update

[terrance511]

gtx780, updated to latest driver cause my dota2 screen/pc froze. after few froze and power restart, the gpu become error code 43 in device manager


history: screen froze happened on older version driver few months ago, but usually goes away with driver update, only happen with dota2, tried another much higher end game like battlefield and it's fine.


note: my monitor output still from the gpu port thou. but only can 1 screen (use to be 2 screen), caues i cant use nvidia control panel, it wont launch.


things i had try and useless:
-DDU clean and reinstall driver,
-update system bios (only manage to update to 1.1 from 1.0 version with msi bios, no response when try to go 1.1 to 1.2, latest 1.6)
-take out gpu and re insert
-windows update
-drag drop vbios flash using nvflash64.exe


what to do next?

thanks !

Does it happen only with DOTA2? Did you try another games besides Battlefield? Did you try some benchmarks to see whether the GPU is stable (FurMark, Unigine Valley...)? If everything else works OK, I suspect that DOTA2 is corrupted and needs to be reinstalled.

the battlefield thing was few month ago when froze 1st happen. did not try any other game.
