I can't enter my computer password unless I first go to another account and switch users. Then the computer allows me to enter my password. do I have some kind of setting wrong? This is a recent problem.
Something or someone has messed with your winlogonui and my prime suspect will always be malware. Go to http://www.malwarebytes.com and download MalwareBytes. Install and update it then restart into Safe Mode with Networking by tapping Function 8 before Windows starts to load.
Run the programme in Full Scan mode and when it completes, click on Show results and then on Remove Selected. It won't harm anything you want to keep. The scan will be quicker if you first remove all the clutter that goes with the Internet and general use so download CCleaner from http://www.piriform.com and ATF Cleaner from http://www.atribune.org. Use both to remove different types of clutter and your system will be better for it.
