So, I keep getting this error when I try to launch CSGO since I installed a Titan Black to my system. I've tried reinstalling my drivers and everything and still the same issue. Not just CSGO either, Fortnite just crashes before getting to the lobby. Anyone have any idea how to fix this? I haven't tried rolling back to older driver versions yet. 

 

Thanks.

I haven't overclocked the GPU yet. And I tried removing my CPU overclock just to normalize the system and still the same issue. Could it just be the GPU isn't getting enough power? I only have a 550w bronze power supply for the time being. I was worried that wouldn't be enough. Should I try under clocking the GPU?

Did you reinstall drivers with DDU?

I didn't. But I can. Should I?

Use Display Driver Uninstaller (DDU) to uninstall the drivers (do it in Safe Mode) and then reinstall the latest drivers from Nvidia's website (in normal boot mode).

I used DDU to uninstall it and reinstalled drivers from Nvidias website (version 391.35) and still the same issue. I'm going to try the second latest version now to see if that's the issue.
