I changed some settings in
msconfig.exe on my computer. Then I booted and advanced. Then I changed my cores from 1 to 4. I'm almost positve that my computer is only 1 core and is an Intel i3. Now Windows won't start and I can't use System Restore.
I have tried 2 system restores and "Last Known Good Configuration".
I am running Windows 7, not Vista or XP.
