errore rundll32.exe - win xp pro sp2

[Vampire]

Ho bisogno di aiutooo, questo problema mi sta facendo impazzire

Ogni volta che apro le proprietà dello schermo funziona tutto ok,ma se cliccko sulla scheda "desktop" l'applicazione si blocca e devo forzare la chiusura... il che mi porta alla finestrina di errore di rundll32.exe (con relativa richiesta di mandare le info a microsoft... l'avrò fatto un centinaio di volte oramai..) .
Con il task manager ho notato anche che il processo mi usa praticamente tutta la memoria .

Ho analizzato l'hd con ad aware, spybot e con l'antivirus.. mi hanno trovato qualche cookie cretino ma niente più: nessun spyware, malware o altro.

Ho anche provato a sostituire il file con la versione presente sul mio portatile (che funziona benissimo) ma senza successo.

Faccio presente che ho win xp pro sp2 e come scheda video una ATI x550 da 256mb



aiutoooo!!!!!!!

ps. non ditemi di formattare, preferisco provare l'impossibile.. prima.
