Everytime I try to boot up my pc, it runs into a bsod that says critical process died. I've tried doing a startup repair, a sfc scan, completely reinstalling windows, starting in safe mode, but everytime I try to do any of these things it just says something along the lines of windows can't complete this request or this request failed or something like that, and then just returns me to the advanced boot screen. I really need help with this, I can't access my pc at all, I recently installed a new CPU if that makes any difference?
