I can't really help you with the System Restore issue other than offering generalities.
I would consider all of the following:
Running system repair several times with a windows installation disc.
Using your recovery discs or recovery partition to restore your PC to the way it was the day it arrived, after backing up my data.
Reinstalling Windows completely using install discs if you have them.
I don't know which of those things you can do or are willing to do.
I do know that System Restore is valuable and works well for me.
The major lesson here is to get a good Windows installation, back up your data, and don't bother with "optimizations" as they can get you in trouble as you have learned.
Good luck.
Maybe someone else has other suggestions.
