@AB de Royse777, do you have any new details regarding your problem? You should always take into account that something else can have an impact on Tor, but the only thing that comes to mind is to look in the settings of your antivirus/firewall and maybe restart your modem.
I have tried everything, my last option as you can read is to reset the system. It will be so time consuming for me that I am still trying to find a good time to do that.Instead of resetting everything, I would still (given that you don't have too much time) go in the direction of trying to eliminate the problem step by step - for a start (if you haven't already) try to reinstall Tor, because as far as I can see the new version is available for download.
Also check if your AV/firewall might be blocking some of these things ->
