I am sorry to hear about that problem. My name is***** am a computer expert with 17 years of experience and I will be trying to help you as good as I can.
You say you are not comfortable with someone login into your computer, but without this, I think no one of the experts here will be able to help you, since this needs to be seen & analyzed in order to be fixed. So may I remotely connect to your computer, so that I can directly analyze and resolve the problem for you while you can relax and watch me doing it on your screen? This is a very safe option too, because JustAnswer is a A+ accredited business with the BBB, you will be watching your screen and we will chat there as well, so that you will always know what I will be doing next while fixing the problem.
Thanks for your patience and best regards,
