|Yes, I did note the space sfc /scannow. I tried it both ways.|
I have gotten it to go into setup and did an over the top reinstall of XP Home. Programs seem to function now but computer is like molassis.
I did go to MS Update and I have now run CCleaner, Eustis registry cleaner. No improvement. Windows Firewall is not accessible. I was able to get into Control Panel and checked Add/Remove but saw nothing strange.
Hard drive light is on full-time.
I have updated Avast and I am going to unplug my internet connection and run a full system scan. This should take 5-6 hours based on past experience. After MS Updates that have just started are done!
I am beginning to suspect that something is running my computer besides me.
As a sidebar, my wife says her computer is very slow as well but she has not experienced the problems I have.
