    I tried booting it without the XP cd in the cd-rom drive, and it kept giving me the BSoD
    With the cd in the drive, it boots fine.

    Hmm. Not sure what to think about that.

    Have you changed your boot order?

    what was the bluescreen error code?

    can you get into the recovery console via the CD and run fixboot,fixmbr, and perhaps a chkdsk /f for good measure.

    This can occur when NTLDR, NTDETECT, or one of the other core boot files is corrupted or missing on the HD. I've only seen it with floppy disks and those three files, but I imagine it applies equally well to CD drives since they can be higher in the boot order then the HD.

    How about this, for looking at the BSOD error:

    Get a video camera, and record the portion of the startup where the BSOD appears. Then play it back frame by frame to see if you can get a good look at the BSOD, and report it here.

    ???

    or use F8 and "disable automatic restart on system failure"...

    That sparked a thought. And since we are dealing with a malware issue it could be the MBR Rootkit.

    Download mbr.exe to your Desktop.

    • Doubleclick mbr.exe and follow prompts.
    • When mbr.exe is ready, it will create a log.
    • Copy and paste contents of that file to your next reply.

      That's all it does. There should be a new log file on your desktop called mbr.

        Stinking rootkits are going to be the death of me man I swear. Sneaky b*stards.

        Thanks BC, your diagnosis tipped of the perps location ;D

        OK, here we go...

        Copy the MBR.exe on your desktop and place it in the C:\Windows folder

        Now click Start > Run

        Type in mbr.exe -f <- Note the space between mbr.exe and -f

        Then click OK.

        Should fix it.

        I should have had you put that in the C:\ directory so unless you have already started just put it there.

          Look where you placed the MBR.exe and there should be a mbr.log

          Please post that log.

          I think your comfirmation will be your computer starting up without the disk.
