Use Windows XP CD to repair the OS.

Yes. Some Windows system files are corrupt. To scan and replace corrupt files,

Start> Run> type "SFC /SCANNOW" and press enter.
Windows will scan for corrupted/missing files and request for Windows XP CD. Insert the CD and proceed.

^^ Am I missing something... You have written that the PC reboots before login screen and yet you have scanned it for viruses?
