This is so screwed up... In Hibit Startup manager I found Fortinet and Zemana orphaned drivers (both programs are long gone)...when I delete them, I lose both mouse and keyboard upon reboot (happens with Zemana and Fortinet.) My question is: How can I repair this from w8.1 which is my alternate OS (dualboot)? Anyone have some insight? Thanks ... Sorry for all the edits.
