Greetings!
It appears you may have something wrong with the application...Have you attempted to start the computer in "safe mode"? I would recommend trying that and then seeing if you can uninstall Origin. After that, see if you can log in normally to the system. If everything seems hunky dory, then see about a fresh install of Origin. Hopefully this is all you will need to do, as I don't think there is anything wrong with your computer itself. Try these steps and then let us know if there is any improvement. If not, we can dig deeper, but I would start with this easy troubleshoot first.
Hope this helps!
