Thanks for your reply, even though it is not good news. Here is the copy of the Process Explorer data while in safe mode. Do I need to try it in normal mode too? Info about attempts to run Speed Fan is below the process explorer info:

I installed SpeedFan from the File Hippo link you gave me prior to doing the process explorer. All of this was done in safe mode. It looked like Speed Fan installation was complete, but when I clicked on run as administrator, I got an error message "speedfan driver not installed. Is Speed Fan Service installed? OK." So I tried to download again and install from FileHippo thinking something did not complete, but I got the same message. File Hippo said it was version 4.52 and in the list of prior versions it also listed 4.52, so I assume the one I used was the final version and the prior 4.52 was the beta version. There was something about possibly needing to reboot, so I tried that and got the same error message. The Almico website also shows 4.52 as the latest version, but in their question and answer section there was a notation that some tools like Norton may interfere with the download. Could Avast be interfering or the Windows firewall or does it not work in safe mode?
Additional questions: I never had a hard drive fail on me to my knowledge, so I don't have any experience in this area. If my hard drive is indeed failing, can I buy a new internal hard drive like at Best Buy and install it? I found a YouTube video that shows me how to remove the back panel of my computer to access the hard drive and memory compartments. I haven't tried it yet. Online reviews said that new internal hard drives do not include connecting cables. Do I need some kind of new cables or can I use what is already there? Once I install a new hard drive, would I be able to use the recovery DVD's to reinstall Windows 8 and get a free upgrade to Windows 10 from Microsoft. Or are the recovery DVD's specific to my original hard drive, and thus require me to buy new Windows 10 software? Would these changes be compatible with my all in one touch screen? If I had to resort to a new computer, I don't think I could use this screen as a monitor for a new computer. Am I correct?
Thanks for helping.
