I'm working on a PC that had some issues recently with a rundll32.exe bug, combofix repaired that, it worked for a few days, now I can't get past the "loading your personal settings" after entering the user's password during Windows startup/login. I tried numerous tricks I found online, like creating a new user account but it also hangs. I uninstalled all my malware-fighting software, including SpyHunter, and uninstalled McAfee. Tried diagnostic startup, no change, tried System Restore but it said I didn't have any restore points (although it is turned on). I can boot and log in to Safe Mode using that same account with no problem. Sometimes it just simply "hangs" after entering the password (loading your personal settings), other times I get the "blue screen of death". I downloaded the "guided steps" fix from Microsoft to repair the registry, it ran OK, but didn't fix the problem. HELP!
