Razer Cortex broke my pc, bsod

This is quit simple, I optimized my computer, cortex fuc**up somewhere with my ram and now I can’t boot my pc, it also boot with cortex settings, witch men’s that I can’t boot my pc, and even I it does, I can barely play, and go on the web before it crash, otherwise I can’t open cortex to restore my optimisation settings because every time I try it blue screen my pc, and I know that even If I uninstall cortex the settings would still be up and still make bsod
