Having trouble logging into existing accounts and some internet sites

[Patrick1929]

In the past few months, I have been having trouble logging into established accounts I have had and been using for several years. Now I am to the point that two main sites I need to get into one of which is my ISP I am no longer able to get into. I get error messages and messages such as "something went wrong, try again later."   I am also being rejected from various internet sites that I click on when I have done a search.  I am a basic user and do not add external programs to my system.  I have Norton 360 Deluxe since I have this PC and it is always current up to date.  I am convinced that something in my system is corrupted and sending out bad information.  We also have a laptop that operates on Wi-Fi through the same router without any issue which convinces me the problem is somewhere contained in my HP PC.  Any help is appreciated.

Have to ask what browser you are using -- because if it is Edge, that is the source of the problem -- because MS keeps tightening the restrictions on its use all the time -- to the degree that I avoid it as much as possible these days.
