Wow! Thanks for the replies and all the suggestions...I am definately going to try them this weekend but I wanted to give you an update on what I tried on Wed.
As you can read in my response to ^gkiefferjfk ^...the PC will not start in SAFE MODE WITH NETWORK SUPPORT. ...so while I was working on other stuff, I started in SAFE MODE thinking I would do disk cleanup, disk check, defrag...things like that and when I went to the SYSTEM TOOLS folder I was reminded of SYSTEM RESTORE...so I tried about 4 or 5 different RESTORE POINTS in May and none of them worked...so...like I said above, this weekend I'll try the suggestions here and I'll get back with you. ...[hmmm, just realized I don't think I started the computer in May - will it create restore points if it's not on? ...my spouse may have turned it on in May, but I don't think I did..-just thinking out loud-]
Thanks for responding.
