I ran spyware (ewido, Microsoft messenger, spybot, spyware, ad-aware and ccleaner) and found passe partout.exe and trojan diamin.t.  I removed them but my sound and cd drivers are somehow corrupted and wont reinstall.  Sometimes I just GET error 39 message and sometimes the system crashes.  I have a dell dimension 4600c windows xpOpen Device Manager and uninstall the existing device drivers. REBOOT and Windows should start the "Found New Hardware" wizard. Point it to your new drivers.Yes - i have done that.  I get an error Code 39 message that a driver is corrupted.  The Catch-22 is I can't put my drivers back in because my cd doesn't work.Can you just download them? A CDROM doesn't really have drivers beyond what Windows USES. Did you try the Windows update site for a source?I can't see to find the right ones.  I have a soundMax sound card and when I try to download I get an error message.  Then when I restart I am told there is an "IO" error and a little box appears  "No ADI codec driver is installed"Can you remove them in Safe Mode?Oh yes.  I have removed them and TRIED to re-install them in safe and regular mode.  I get Soundmax installation AUDIO driver failed message - I get "No AD1(or I) codec driver is installed message" and I just noticed my plug and play software is messed up Quote
