Thanks rshaffer61 for continuing to help.
I completed all the steps you recommended and ran a Malware scan with minimal performance results, although I did find some Malware, so all is not for nothing
Interestingly, I continue to have the computer freeze up and the screen go blank - only a re-boot gets me back going. Reviewing hardware in Device Manager, I noticed a yellow indicator on the Promise FastTrakController. The error I see in System Event Viewer that corresponds to the freezing issue says it is a fasttx2k error saying "Internal error in data structures for . (no words between "for" and period).
Driver details on the controller states "This device cannot start. (Code 10).
I tried installing the driver from the MB disk and also from the floppy, but get a message during the driver search that windows cannot find a better driver than the one installed. Troubleshooting suggested uninstalling then reinstalling the driver. Should I use the disk, floppy or try to find one on the internet?
As background, because I was getting the fasttx2K error, I have changed BIOS for IDE (not RAID) configuration as my OS is on an IDE HDD. I disconnected the backup HDD (SATA) from the MB and the freezing didn't occur for about three days, but has now returned.
Any other advice would be appreciated.
