I went to cmd admin and enabled driver verifier for all drivers then it said I should reboot. So I rebooted then saw the windows sign and the losing circle beneath it spinning then it says DRIVER_VERIFIER_IOMANAGER_VIOLATION. Then it collects info and I'm stuck in a black screen with an underscore flashing at the top left. Then when I hold down my power button I get the verifier bsod again it collects info then it restarts my pc and I'm in the black screen with the underscore again. I seemingly have to way to cmd or to boot into safe mode. I have windows 10 btw. I have my windows 8.1 disk that my pc came with so if there is no way to fix this then how can I restore my pc?
