As such, IMMEDIATELY create a second user account/profile with admin privileges. In fact, create a third admin account also, as a backup. Once that's done, login to the second account and see if the same problem occurs. If not, then start copying all the files, documents, and personal folders from your previous account to the new account. Once that's done, operate out of the second account for a while and when you're comfortable using it, delete the first account.

Hope this helps.
