Hello, I recently upgraded my computers power supply and graphics card to brand new ones. When I oot my computer up, it is now stuck on "windows is starting" screen. When I try to boot in any of the safe modes, I load up to atipcie.sys then my computer freezes and never continues to load the rest of safe mode. When I click repair computer, I get stuck at the Blue windows screen, and as soon as it starts up a cmd box pops up then quickly closes before I could even read it. I also tried loading last working configuration but no luck. Even when I load boot recovery mode, a cmd box comes up quick then closes and continues to be stuck. Any help?
