I used the Glarry utilities today and could not restart my computer.
Repair options were to use system restore, but it would not work.
I tried with the Win7 dvd, but all I could do is reinstall.
Installed fine, but I noticed there is about 60 gbs used on my c drive.
I know before any of this happened I had about 40 gbs used on C:
I see I now have restore points going back about a week.
What would happen if I tried one of these restore points from before I crashed?
