missing files-"winlogon.exe-Entry Point not found"

[Guest]

any suggestions for those of us who got XP installed on purchase of PC? I am getting a "winlongon.exe-Entry Point not found" error and now I'm continually rebooting. Of course, I did not back up )-:
I don't have an XP CD because it came with the pc and from what I can tell, that will be the only way to fix this mess.
