Thanks as always for your valuable advice. I've never had a harder time with a OS before, so I am a bit leery. I've found some that I could explain, like ATI display faulting when the screen goes off after 15 minutes. I am basically looking at frequently recurring Administrative Event Errors. Took a while but got rid of a recurrent SASCore failure, due to Windows uninstaller and Revo Free's inability to totally clean, apparently 64 bit programs.
A problem I may be causing myself is that with Advanced SystemCare Pro and doing disk cleanups there are options such as Per user archived Windows Error Reports and System archive Windows Error Reports and Setup Logs, which I had previously been deleting. Also a I've cleaned up system files. Since I don't really know what they are, they may be a part of the issue??
I will certainly check your idea.
