    and remove all the harmful files in my computer the bsod
    (blue screen of death) appeared and it restarted!!!
    then i used smitfraudfix and halfway throught the process the bsod appeared.
    it does that evertime i try to scan for files...
    i then tried to reinstall windows using repair...
    halfway through the process the bsod appeared again...

    alex rubio,

    You're probably infected with a corrupted program. To try to get into safe mode, start hitting F8 key. If this doesn't work:

    1. Boot to the Recovery Console: Put in your Operating System CD > Reboot > Press any key when prompted > Press 'R' (when setup is done loading) > Login

    2. C:\Windows prompt is presented > Type Listsvc > Press Enter

    3. Locate the filename ntio256.sys (which causes BSOD)

    4. At C:\Windows prompt > Type Disable ntio256 > Press Enter
    *If you receive an error, check spelling and if the service/driver was under Listsvc.

    5. Type Exit

    6. Boot Operating System again
