I have a Dell, Windows 10, i5-4460 CPU 320 Ghz, 8 gb, 64-bit operating system. For some reason, after I start my computer and don't use the Start button for a while, it becomes inoperable. I can right-click on it and get it to shut down, and when I restart it, it works fine. Also, I have never had a computer that I had to type a password to use it and this one has it. Is there any way to bypass that and just turn the computer on and start using it? I have looked at settings and everything I can figure out (not computer savvy) and am scared to change anything since I'm not sure about it. I know these are small things, but they are bugging me, especially the Start thing.
