    Extract the Kaspersky TDSS Killer tool onto a USB drive, and then use your Windows DVD to boot the laptop. Select "repair my computer", and open a command prompt. Enter the path of the tdsskiller.exe
    file, and press enter. Let it clean out anything it finds.
    For some reason I did not think that a USB drive was accessible from the repair console. So I've learned something. But at any rate, when I go to the path on the flash drive and type tdsskiller.exe I get the following msg:

    The subsystem needed to support the image type is not present

    I even tried copying the exe file to the windows directory and running it from there, but I got the same msg.

    Are you using a 32-bit or a 64-bit Windows DVD? If 32-bit, download the 64-bit Windows Repair Disc ISO and try using that instead.

    Don't know how I can tell - it's an iso disk I created about a year ago for someone else. I simply made 2 copies and gave them one. The guy whose PC is having the problem did find a Dell Reinstallation DVD - 64 bit - Home Premium. I'll give that a try.

    I also notice that the time seems to be constantly off by an hour or 2 or 3 every time I go into the BIOS.

    Got the same msg when trying to run TDSSKiller
    The subsystem needed to support the image type is not present
    using the 64 bit Dell DVD

    And I typed in Time on the recovery prompt and got 21:30 instead of 18:30 (we are in Eastern Time).

    I have to go out for the evening - will check back in about 4 - 5 hours

    Can't you use System Restore and restore to a point before the problem started?

    System restore now gives an error, no matter what restore point I choose.

    Have initiated BIOS change to ATA (as per the Dell article), and also downloaded the Intel Matrix Storage Driver (using my old reliable Window XP PC - a quality OS - why didn't they just leave well enough alone?) onto a USB drive, but when I put the flash drive into the Windows 7 laptop, and boot that PC using the Dell Windows 7 64 bit disk, and get to the command prompt, and type in R130119 (the driver previously downloaded).....whew....

    I get the same old msg:
    The subsystem needed to support the image type is not present


    Later today I will click on the Load Drivers option from the CD boot and see if I can get it to work that way...
