Thank you Shane. Thank you Boggin. Your inputs are most appreciated. Yes, Windows 7-32bit. No, I am not in possession of the original Window disc. The computer was given to my wife in an unusable condition and it was my project. I approached these upgrades with a lot of caution, mostly because of the time and effort already spent in the running restoration, a total learning for me. When I took on AVG Internet on a trial basis I decided that now was the time to proceed with SimpleTweaking and Tweaking.com. I eliminated several programs I felt were superfluous, possible conflict, or unused. I scanned and cleaned consistently over a 4 day period, including CheckDisc and File, each time after eliminating or changing I would scan again, with everything. All came up clean. Considered everything I did and approached it with a meticulous mind-set. When I applied SimpleTweaking it became immediately apparent that the utility had done a fine job, absolutely no doubt about it. I decided to proceed with the main Tweaking. I did not go into this totally blind. If I didn't know what was being done I researched it and based my decision(s) in part on that research and partly what I had accumulated knowledge-wise and if there was any doubt stayed with the defaults. I did (through Registry Backup) two registry backup, then two file, and 4 restore points. At points along the way in running the utility I was flagged for missing or corrupt files, my hard drive was almost full, SOL(?) file missing, losing Homegroup, sporadic Internet (I'm wireless. Cable, but broadcast inside house and was now getting connections to weaker signals when before I had a solid '5-bye-5', no ability to update anything, and a BUNCH of other flags that came and went too quickly to write them down. If any connection to Internet was made it was SLOW and usually would not take any redirection. Toward THE END I found that AVG had done something to my firewall and had a death grip on everything. The Wdo's settings for the firewall were correct, but AVG would not let go, even when disabled. I finally uninstalled AVG, but did not get firewall back or stable connection to the Internet. The offline performance continued to deteriorate until I was left with nothing but a forced shut-down. After restarting, which took inordinately long, I went into Safe Mode (no Internet) and again ran all scans and checks. Nothing showed up. Tried, progressively older, 3 restore points. Made it worse. Then I made probably my final misstep and tried a registry restore. That did it. After (now always) a forced shut-down I have tried successively to boot in Safe/Safe with networking/cmd/normal. After the Pentium logo it goes to loading Sys32 files, hesitates, then blackscreen with an active mouse and no cursor, although the cursor does appear momentarily in the upper left. I have tried all that you suggested (and more) at different times in the boot process and the only thing that produces anything is ctrl+alt+del, which takes me back to the Pentium logo and we start all over again. Ooops. Looks like I'm gonna need a bigger boat....
