BC;
I've been racking my brains to recall whether anything new, software or hardware, was added to my system just prior to the problem appearing and I can be fairly certain that no new hardware was.
One problem is that there was no sudden great revelatory moment when it became apparent that there was a problem. It just gradually dawned on me that my internet connection was disconnecting rather more frequently and I then realised that it was happening when I clicked on the "Safely Remove Hardware" icon. It was more of a "Well, isn't that odd" feeling rather than a "SOMETHING HAS GONE WRONG" moment. I did not, therefore, suddenly halt everything and go back over the preceding days/weeks to try and identify the culprit. However, as I haven't added new hardware for yonks (the last was an External HDD I use intermittently only for backing up) I have tended to dismiss that as the cause.
I can't exclude the addition of a new programme as being the precipitatant of the problem but that is simply because new ones are being added all the time, especially by my grown-up son who also uses this PC. However, if a newly installed programme was/is the culprit, I know of no practical way of identifying which one of the myriad it may be.
In the meantime I await the pontifications of my ISP - as usual the so-called "Help Line" was nothing of the sort and so they are going to come back to me (eventually). I won't hold my breath for an early reply!!
Thanks all.
