Nobody can help you remotely if you don't provide enough information to diagnose your problem.
And, if you don't know what information to provide, then I advise you to find someone who is willing to have a private screen sharing live, one-on-one session with you and help you solve the problem.
Just never give them direct access to your computer data files!
Screen sharing is enough!
