Hello, I am trying to use Samsung Magician to wipe my SSD. I would use DBAN, but I heard it's not good for the SSD and it doesn't fully remove everything.

I created the bootable USB, everything is OK. I go to restart my PC and I select the bootable USB as first priority. Keyboard won't work, but LED's turn on. The keyboard literally worked right before I select the USB as the bootable device. I've tried unplugging my computer, switching USB ports, I've reset the Bios to default settings, I've made sure USB legacy was enabled. I was going to DBAN and that worked at first, then I reset my PC and it doesn't work. wat do. This is urgent, please help
