How large is your hard drive? I think that’s pathetic that it only gives you six restore points.
If I were in your shoes, I would pick the oldest point, and try it. If it does not work, you can always undo it.
Also, there is wisdom in a disk imaging program such as Acronis True Image, or Symantec Backup Exec (I think the home version may be called Norton Ghost). When you have a clean install, take a disk image on a separate external USB drive, and then put that aside. If you ever have a major hard drive crash, or just need to get a good, clean ‘drive wipe’ to return your system to fresh it can save you just hours and hours. Then get another drive to do daily restores. Set a monthly full restore point, and then daily incrementals. That way, if you know your machine worked fine last week, you can always roll it back.
Personally I also keep a backup of D:\ (data).
I’m not sure what else to tell you, than just to pray, and try the oldest restore point you’ve got.
I wish I could be more help. Perhaps someone else will have ideas?
