Also check that you are not infected with a virus. Applicable software: Norton Anti-Virus, Mcafee, AVG.

Try going to BOOTDISK.com and spend some time checking everything out.
They offer some downloads that can even wipe out an NTFS partition, which for the life of me I've not been able to find how to through MS or elsewhere!
