Originally W10 upgrade on W7 - that fell over after about a month.
A clean ground up install isn't much better...................
When W10 imploded - I couldn't repair, re-install or anything. The only cure was to overwrite the HDD by installing Linux, then clear all that out and start over with W10.
Pretty much every application starts off; "not responding", the HDD activity light is busy almost all the time. The cursor frequently changes from an arrow to a little blue circle, either way the response is usually hesitant - if it gets around to moving at all.....................
It was tolerable when I was using freeAVG, someone told me that was the cause of the problems and I should switch to Avira - I did that and now the PC is pretty much unuseable.
When I tried to go back to AVG, the installation failed, so it looks like I'm stuck with Avira.
Thanks for any help.
