To both of you: I've downloaded Speccy. Thanks for the reference. I want to thank you also for comforting me about my CPU. Old or otherwise, it's good to hear it is dependable. I might have gone out and spent a lot of money on a new one I don't need. It won't do any spiking of individual sections that I can detect in the graphs of CPU activity. They only show one, overall, graph.
Now I know I've got to look elsewhere for the cause of my problem.
I will use Speccy, but worry about publishing it. It's already easy enough for hackers to get a few intimate details about my system. Giving them access to the whole kit and kaboodle sounds unwise. It doesn't mean I don't trust those who maintain the site, either. It means I can't know what might be done when other people control or access the site. Once it's up on the web, it never gets off. My equipment will probably croak before any danger occurs, but I'd still like to know about this unique site mentioned. Particularly how the data can be relied upon to NOT be abused.
Maybe I'm being a bit paranoid, but I've been hacked several times, requiring format of C and reinstall of the OS. I'm used to it, but it's a nuisance. Once, while in an offline game, I got a popup from Windows apologizing that it couldn't open "Email+Passwords.doc." Of COURSE it couldn't! I hadn't reinstalled Word after the last hack! So I did something naughty.
I installed Word, then removed the contents of the file to another .doc with an obscure name. Then I refilled the file with language that would ionize the atmosphere if spoken. Not ladylike, I know, but I just couldn't resist. Then I hoped they'd try again. Tee hee.
I await a response about the security of the unique site before publishing Speccy results. And THANKS! Your site has always been responsible, and I have great respect for you.
