I have an older E-Machines system running XP Home which I periodically
update---A couple days ago I was connected to the net and downloading some
Windows updates when the system froze ---I could not  break the freeze with
keystrokes and the power switch wasn't working as well ---My only option was
to cut power ---Now, the following message appears when I boot the system
(both normal and safe modes)

winlogon.exe - Unable to Locate Component

The application has failed to start becasue ole32.dll was not found,  
Re-Installing the application may fix this problem ...O.K. button

Is there anyway to fix this problem without using the E-Machines receovery
software (which will wipe out all of my data)    Thanks   Don
