My main rig will no longer boot into windows. This started happening after upgrading from a FX 8320 --> FX 8350 and forgetting my password . The PC gets the the windows logo then the screen turns black with just a mouse cursor. Everything is stock & default. I really don't want to do a fresh install as i have a lot of files/apps i haven't backed up that i don't want to lose. Could someone please help me.
