I recently had to switch GPUs from a Radeon R9 390 to a GeForce GTX 970 because the drivers kept crashing every time I would boot up the PC. For some reason now some of my games crash within a few minutes of starting game play. Could there be some drivers still installed from the old card and conflicting with my new one? I've went through control panel to uninstall the programs, and everything that I could find from the old software. Any help would be appreciated.
