Hello,
First you should consider doing an offline scan of your computer just in case this issue was caused by malware (means boot from a resque CD like UBCD or Hiren's Boot CD).
After that, you can navigate to C:\Windows\System32 and locate rstrui.exe - that is the System Restore app. Double click it directly to launch it.
